7.6              Geometry in module Point fixing

7.6.1 Standard editor

 

 

In module Point fixing the number and position of the plate or clamp holders can be determined. There is a standard input editor and an expert editor available.
For calculating a point-fixed disc, only single glazing is possible.

For the simple, symmetrical arrangement of plate holder in the disk, the number of holders will be selected from the list, and the distance (ex and ey) of the plate holder to the glass edge in X and Y direction can be set.

 

With the symbol  following window will appear:

 

The characteristics of the intermediate layer, marked yellow in the image, can be changed under support condition glass. be changed are modulus of elasticity, and thickness the material. These fields are preset with experience values.
The support conditions point fixing refers to the characteristics of the point holder. The diameter of the bore and the clamping plate often differs from the default values. The input fields cz,x,y contain the spring stiffness of the point fixing.

 


 

 

7.6.2 Expert

 

 

 

The Expert editor is separated in four parts:

1.    Installation angle

2.    Polygon

3.    Storage

4.    Point fixing

 

For 1. à The angle of installation can be set here

For 2. à Geometry of the glazing is defined here by the coordinates of the corners

For 3. à Here you can choose the support of the glazing between free, clamped and fixed

For 4. à Point fixings can be added with the icons, or by defining the coordinates of the drill holes. The point fixings can be put positioned at any place

New corners or point fixings can be added with the symbol

To delete any position, press      

 


 

 

7.6.3 Grid input for point fixing

 

A grid input is available for positioning point fixing:

7.7              Clamp mounting

 

Clamp mountings can be added with the button  (next to the field Storage).

The following window will be opened:

By selecting the sides top, bottom, left and right, clamps can be added on the glass edge. They will appear in the sketch. In the box e [mm], the distance of the clamp holder to the glass edge is defined. The number of clamp holder on one side can be changed via the arrow symbols. The distance of the clamp holder is displayed in the column Distance.

 

The geometry of the clamp holder can be changed with the symbol  in following window:

Input values here are:

dE = thickness of the interlayer from glass and clamp holder

E = E-modulus of the interlayer

a = length of glass in the clamp

b = length of the clamp holder

 

After you submit the clamp mounting, they will be added to the glazing.

The rim is divided into sections, and the support of the parts is set automatically. In the field Polygon you can see the coordinates of the coordinates, where the mounting changes.

7.8              Geometry in the module Walk on

7.8.1 Standard editor

 

The disk assembly may according to DIN 18008 part 5 consist only of VSG with at least three layers of glass. Therefore under disc is only single glazing adjustable.
As installation brackets are values from 0 ° -79 ° for selection.
Geometry and storage are selected from the list, and the dimension is entered in millimeters.

 

7.8.2 Expert editor

In the expert editor, the geometry of the glazing can be entered with the coordinates of the corners.
The sides can be supported individually (fixed, free, clamped).

 

 

7.9              Membrane stress

 

 

The calculation with membrane stress is only available under the following requirements and approved according to DIN 18008-1:

·         Add-on „membrane stress“ was activated

·         Shape rectangle

·         Four-sided support

·         No taking into account shear coupling with laminated safety glass

 

The consideration of the membrane stress is quoted in the proof::

By right-clicking on a layer of the drawing you get this context menu.

The menu entries correspond to the points described above.

Additionally there is the possibility to modify the thickness of the marked glass by choosing the feature „change thickness“, whereby the new thickness can be typed in directly:


 

8.1              Define pane

 

 

 

8.1.1 Type of glass

 

 

Set the type of glass here.

For laminated security glass only float, TSG (float) and TVG are available.

 

 

8.1.2 Single glazing

 

 

  

Specification of the thickness in mm


 

8.1.3 LSG

8.1.3.1   LSG symmetric

 

 

  

Specification of the thickness for the single glazing panes in mm

 

Thickness and type of interlayer

 

Number of glass panes and the consequent LSG structure

 

Substitute thicknesses for the calculation of the deflection (dw*) and the stress (ds*)

 

 

8.1.3.2   LSG asymmetric

 

With the new FEM-calculation it is possible to calculate asymmetric multilayer safety glass. The glazing can be made of max. 8 glass panes.

 

Therefore you just have to set the material and its thickness:

You can consider a shear coupling with asymmetric LSG, too. The thickness of the glass pane can be different by the factor 1.7 according to the standard. Otherwise the Thickness factor will be displayed red but a calculation is possible


 

 

8.1.3.3   Shear coupling at LSG

 

When the hook is set, the specification of the shear coupling of the interlayer in N/mm² can be made.

 

Requirements:

·         Only rectangle

·         No membrane stress

·         Number LSG panes = 2 in module Standard and Fall protection

·         Up to 8 glass panes when calculating symmeric LSG

·         For FEM-calculation:  8 glass panes with asymmetric structure possible

 

Please note

·      Additional to “total bond” and “without bond” the LSG will be calculated “with thrust module”.

·      The calculation “with thrust module” has no influence on the results of verification (OK, stress/deflection too big).

è In individual cases the user has to decide, if a fulfilled proof “with  thrust module” replaces a not fulfilled proof „without bond“.

The button sets the wind and snow loads to "manual" and the loads to "0,00":


 

10.4          Buildings

 

 

Building dimensions

Determination the building dimensions

 

Internal pressure

The internal pressure will only be considered, if it is a hall-like building. Please quote the amount of apertures on the walls 1 to 4 each time under “Wall open”.

With “Opening height Zi” you quote the reference height for the calculation of the internal pressure.

When you choose “Hall-like building”, there appears an additional result window for the internal pressure on the tab “Analysis”.

 

 

10.5          Unit/roof

 

 

Unit

Here you choose the unit, in which the window will be built into.

The roof pitch will be set to the installation angle from “Geometry”.

 

Position of installation

Position of the glazing inside the unit

 

Jump in height

Specifications to the determination of the snow load at jumps in height at roofs according to DIN EN 1991-1-4, 5.3.6.

 

b1        Width tall part of the building

b2        Width low part of the building

b3        Width of the load from that the snow can slip down to the low part of the building

hH          Height of the height difference

αH        Roof pitch of the taller part of the building

ls          Length of the drifting

            ls = 2 * hH

            whereby 5 ls≤ 15 m

µ1        = 0,8

µs           Shape parameter for slipping snow

µw        Shape parameter for snow taking account of wind

 

µ2           = µs + µw

 

Calculating µs

αH≤ 15°:

            µs = 0

αH> 15°:

µshas to be calculated by means of an additional load of 50% of the largest entire snow load on the bordering roof pitch of the upper roof area. This entire snow load will be steadily set with µ1 = 0,8, also for roof pitches >30°, so that there will not be calculated a load, where several parts of the snow load are already slipped down.

It is accordingly clear:         0,5 * b3 * 0,8 * sK  = 0,5 * µs * sK * ls

And here from:                    µs = 0,8 * b3 / ls         

 

Calculating µw

HH 0,5 m

            µw = 0

HH> 0,5 m     

µw = (b1 + b2) / 2hH≤  2hH / sK - µs

 

Margin µ2

Generally:                 0,8 ≤µ2≤ 2,4

For b2 ≤ 3 m:             0,8 ≤µ2≤ 2

For sK > 3,0 kN/m²:   1,2 ≤µ2≤ 6,45 / sK0,9

North Ger. Plain      2,3 * µ2≤ 4  which indicates  µ2≤ 1,74


 

10.6          Add-On Porch

 

In this add-on canopies/porches according to DIN EN 1991-1-4 / NA, Attachment NA.V can be calculated.

To obtain the maximum wind load with a canopy, the edge distance must be set ux= 0.
The calculated wind load is independent of the wind direction and is equal for all wind directions.
Intermediate values in DIN EN 1991-1-4 / NA, Table NA.V for the proportion between hv / h and hv / dv (upward load) are interpolated

 

To determine the snow load, the height difference can be considered.

 

10.7          Analysis

 

 

The parameters for the wind and snow loads will be summarized here.

1) Payloads in factories and workshops are considered predominantly static. In individual cases, often repetitive loads are classified         

   according to the circumstances as not predominantly static loads.

2) These values are minimum values. In cases with higher loads, the higher loads apply.

3) For the transmission of loads in rooms with ceilings without adequate lateral distribution on supporting components, the specified value can de decreased by 0.5 kN / m².

4) With the combinations of actions, the effects of the use category of the building or building unit must be assigned.

5) If the proof of the local minimum carrying capacity is required (e.g. as in components without adequate lateral distribution of loads), the proof has to be performed with the characteristic values for the concentrated load Qk without superposition qk with the area load. The area for Qk includes a square with a side length of 50 mm.

15.1          Load case glass break

 

It is possible to define an own load case to calculate the case that an upper glass pane will break in an insulated glass and the shards will lay on the pane below. The load cases for a glass break are preset. There is also the possibility to define such a load case by the user. Therefore you have to select a load case B1 to B3:

Afterwards please click on the button  to add a new load case. A window to enter the psi-values will be opened.

The case “break of the outer pane” (DIN 18008-2, 5.8) is an out of the ordinary load (EN 1055-100, 9.4, Gl. 15).

With Ad = own weight of the shards, following load cases (preset in GLASGLOBAL®) are resulting (OW = own weight):

 

Height under 1000m

 

B1: OW + OW shards + snow (psi1=0.2)  [+ wind (psi2=0)]                                   kmod = middle (0.4)

B2: OW + OW shards + wind pressure (psi1=0.2)  [+ snow (psi2=0)]           kmod = short (0.7)

B3: OW + OW shards                                                                          kmod = constantly (0.25)

 

Height over 1000m:

 

B1: OW + OW shards + snow (psi1=0.5)  [+ wind (psi2=0)]                                   kmod = middle (0.4)

B2: OW + OW shards + wind pressure (psi1=0.2)  [+ snow (psi2=0.2)]        kmod = short (0.7)

B3: OW + OW shards                                                                          kmod = constantly (0.25)

 

15.2          North German lowlands

 

Another load out of the ordinary, north German lowlands, can be set in the field wind and snow load. The load cases are shown in the load case combinations with the designation “S1” – “S4”. They are added automatically. Own load cases can be add with the symbol , like described in chapter 15.1.

17.2          Edge seal - edge load

 

 

Here the maximum edge load for the edge seal is determined. GLASGLOBAL® determines the edge load on the safe side with the coefficient for rectangles. For square formats there would be lower edge loads.

 

18   DIN 18008-2:2020-05

 

In GLASGLOBAL® the proof has been updated according to white print DIN 18008:2020-05.

According to DIN 18008-2:2020-05, the partial safety factors on the exposure side and partly also on the reaction side may be reduced for multiple-glazed units (MIG) with a surface area of ≤ 2 m².

It can be assumed that this is a "rule of technology". However, the application must be discussed with the client.

18.1          Requirements

 

MIG up to 0,4 m²

or

MIG up to 2 m² with the following minimum thicknesses:

- 4 mm for monolithic single glasses

- 3 mm for monolithic single glasses made of TVG or ESG

- Laminated safety glass made of 2 mm single panes

- 2 mm for monolithic single panes of TVG or ESG in the inter-pane cavity of triple MIG

 

 


 

 

18.2          Settings

 

The specification of the underlying standard is defined in the specifications:

 

 

 

 

 

DIN 18008-2:2010-12

Previously used and currently still valid version of the standard

 

 

Draft DIN 18008-2:2020-05

18.5          Glassthickness 2 mm

 

According to DIN 18008-1:2020-05, an increased partial safety factor γM must be applied for the thickness of the individual glass sheets of 2 mm.

 

è Thermally toughened glass (DIN 18008-1:2020-05, 8.3.6)

γM = 1.6 (instead of 1.5)

 

è Glasses without scheduled thermal tempering (DIN 18008-1:2020-05, 8.3.7)

γM = 1.9 (instead of 1.8)

 

The increase of the values for γM is taken into account by GLASGLOBAL®.

24      Sound database

24.1          Glossary

 

Evaluated sound insulation dimension R¬¬w

Rw is the sound reduction index of a building component, evaluated on the basis of a standard curve (to take human hearing into account).

It is given in dB.

 

Spectrum matching values C; Ctr

According to EN ISO 717-1, the spectrum adaptation values C and Ctr ("tr" for road traffic "traffic") denote a value in decibels that must be added to the singular Rw to take a specific sound spectrum into account.

The complete specification of the sound insulation of a component is given as follows:

Rw (C; Ctr) = 40 (-2; -5) dB

 

 

24.2          Product search on the main screen

 

The sound database can be called up in the main mask by clicking the following button:

 

 

You will receive a list of the deposited products for sound insulation:

è  The available functions are described under point 2

24.4          Determining Rw from database

 

When searching the database, the type of gas in the SDR is not taken into account.

To determine the sound insulation value for an existing glass structure from the database, proceed as follows:

 

è  Call up product search

 

è  Display of the products that match the current structure

 

For products to be displayed with a sound insulation film (e.g. "..|PHON..NC"), the design must also include a sound insulation film (e.g. Trosifol® SC Monlayer or Multilayer) in the specification.

 

1 Default = current structure

 

2 Larger SDR allowed: products with a larger SDR (orange) are also displayed. Check is off by default because the comparison is on the insecure side.

 

3 User-defined only displays only products that have been saved by the user.

 

4 Legend for the individual colors

The nature of the gas in the SDR is not taken into account.

 

The structure is identical to the specification, i.e. all thicknesses (glass, SDR and composite layers) are the same.

 

All thicknesses (glass and SDR) match. The composite layers are not taken into account. For laminated safety glass, monolithic panes of the same thickness are also determined without taking the composite layers into account.

Only monolithic panes of the same thickness are determined for monolithic panes.

 

At least one glass thickness or SDR is less than the specification. The composite layers are not taken into account.

At least one SDR is greater than the specification and the glass thicknesses are less than or equal to the specification. The composite layers are not taken into account.

25   DIN 18008-6: Accessible and fall-through resistant glazing

25.1          General

According to DIN 18008-6 the addon "Betretbar" was implemented in GLASGLOBAL®.

In DIN 18008-6 the following types of glazing are distinguished:

 

-       Accessible glazing

Glazings which can be entered for maintenance work (e.g. cleaning)

-       Crash-proof glazing

Glazings that are not accessible to pedestrians and are located near areas that can be entered for maintenance work.

 

25.2          New project

 

The Addon for DIN 18008-6 is called up in the main mask via the following button:

 

 

 

In the following, only the entries that differ from the basic module (18008-1, -2) are described.

25.2.1           Geometry

 

The geometry is limited to rectangular discs supported on all sides.

According to DIN 18008-6, values from 0° to 100° are possible for the installation angle.


25.2.2           Product

 

Specifications according to DIN 18008-6:

- The regulations of DIN 18008-2 or 3 apply

- Use of wired glass is excluded

- ESG or VSG should be used for the top pane of multiple-pane insulating glass

 

 

25.2.3           Accessible/fall through

 

 

Accessible with snow

Glazing should also be walked on in snow

Single load is superimposed with snow load when the load-bearing capacity is verified (Ψ0 = 1.00)

 

Accessible without snow

Glazing should not be stepped on when there is snow

Single load is not superimposed with snow load when the load-bearing capacity is verified

 

Fail-safe

Glazings that are not accessible to pedestrians and are located near areas that can be entered for maintenance work.

 

Single load

According to DIN 18008-6, the static proof for a substitute person load of 1.5 kN distributed over a contact area of 100 mm X 100 mm must also be provided.

25.3          Printout

25.3.1           Inputs

 

The entries for accessible or fall-through resistant glazing are made on the first page:

 

 

25.3.2           Verification of bearing capacity

 

Following the standard load cases, the load cases for the individual load are displayed. It is not necessary to check the serviceability here.

 

 

 

25.3.3           Verification of load resistance and residual strength

 

The verification is carried out according to DIN 18008-6, Appendix B.

If the mathematical verification is not provided, the results text refers to the necessity of an experimental component test.

 

The results of the verification according to Annex B are given at the end of the printout.

 

In the case of multiple-pane insulating glass, only the bottom pane is always to be verified here.

25.3.3.1Accessible glazing

 

 

Lower pane

è Intact glazing: P = 12.7 kN (basic energy 225 Nm)

è Upper disc broken: P = 8.5 kN (basic energy 100 Nm)

 

 

 

 

25.3.3.1 Crash-proof glazing

 

 

Lower pane

è All VSG layers are applied

è P (basic energy 225 Nm) for installation angle = 0° (horizontal)

è P (basic energy 100 Nm) for installation angle 90° ± 10 ° (vertical)

è Intermediate values (0° to 80°) are interpolated linearly

è Multi-pane insulating glass, ratio thickness upper to lower pane

è ≤ 1.5: Point load with 50% of the base energy

è > 1.5: Point load with 100% of the base energy


è  

 

25.3.3.2 Addition under "Break “

 

For the category "Accessible", the load case for "Weight + single load" was added under "Break":

 

For "fall-through proof" no individual load must be verified under "breakage".

 

25.3.4           Result display

 

The result display has been changed as follows:

If the verification of load resistance and residual load capacity according to DIN 18008-6, Appendix B is not fulfilled, this is now displayed more clearly:

 

 

 


 

 

25.3.5           Size matrix

 

The verification of impact resistance and residual load capacity according to DIN 18008-6, Appendix B is now also taken into account in the size matrix.

If the ultimate and serviceability limit state design has been performed for a dimension, but not the impact resistance and residual capacity design, this is indicated by ">>P" for "pendulum impact".

 

 

 


 

26   General design approval Z-70.3-267 (DIBt)

 

According to the general type approval number Z-70.3-267 (DIBt)

https://www.dibt.de/pdf_storage/2021/Z-70.3-267%281.70.3-9%2121%29.pdf

values for k­mod deviating from DIN 18008-1 may be used for linearly mounted glazing made of multiple-pane insulating glass.

2.  Set settings:

 

 

 

3.  A note on the changed kmod- values is made in the results overview:

 


 

 

4.  A note appears on the printout and in the editor:

 

 

 

 

 

Notes

è The processor is responsible for defining the kmod- values

è Only for extreme cases (almost no temperature stress) applies:

kmod(medium) = 0,43

Example: SZR temperature differences in summer < approx. 2 K and in winter > approx. -4 K. For this case, the stress from air pressure change can become greater than from temperature change. Otherwise applies  kmod(medium) = 0,58.

è The adjusted values in the defaults remain until they are changed again.
