For vertical glazing, according to DIN 18008-2:2010-12 section 7.4 or
DIN 18008-2:2020-05 section 6.1.5, the decisive criterion is not the deflection criterion 1/100 of the span (or 1/65), but the remaining support width with existing chord shortening.
For this reason the standard display Proof OK appears with additional information on the maximum chord shortening:

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.
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
A grid input is available for positioning point fixing:

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.
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.
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).
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::

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

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. |
Display of the load cases for the procedure of furnishing proof:
Adds a user-defined load case. The input will be made on the following interface:

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)

Proof (FEM Images)
If you calculate a project with the module Point fixing or Walk on, due to the FEM calculation, there is an additional result printout. This includes for each load case a color gradient image of stress and deflection.
On the last page of this printout is a FEM-sheet that represents the main characteristics and the generated FEM grid.
Please note:
· Will be calculated automatically
· Specification of the load case whereby the maximal deflection and therefore the maximal string shortening occurs.
· max. string shortening = 8 * fmax² / (3 * supporting width)
Output at the proof (result, 1. site):
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.
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.
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
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
White print of the standard. Its use should be agreed with the client.
The user can also determine the depth of verification:
The set detection depth is indicated in the result display and in the printout:
If calculations are carried out according to the new draft standard, this is clearly indicated in the mask and on the printout:

Notification upon verification according to 6.1.4 2) and 6.1.4 3)
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®.
Here the possible glazing thicknesses outside and inside will be detected, for whom the static proof with the recently lodged loads is fulfilled.

In FEM images in the navigation, you can show the results of the calculation graphically when you calculate in Point fixing or Walk on module. Therefore we choose in the navigation from the list "FEM graphics".
In the
header of the graphic interface the displayed load case can be selected. You
can choose between stress and deflection, and which disc you want to display.
Using the mouse wheel can rotate the graphic freely in any direction, and the
deflection can be increased by any factor.

In GLASGLOBAL® FEM a new calculation kernel was implemented.
So far version 05 was used here.
Now the used version can be defined in the defaults (default = 08).
Version 08 leads to better results due to the finer meshing.

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
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 Setting the filters and searches
è „Rw", "Rw + C >=" and "Rw + Ctr >="
The required sound insulation value is taken as the minimum value and all products with a sound insulation value higher or equal to the specification are listed.

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.

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.
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.
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.
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
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.
The entries for accessible or fall-through resistant glazing are made on the first page:
Following the standard load cases, the load cases for the individual load are displayed. It is not necessary to check the serviceability here.
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.
.
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)
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
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".
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:
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".
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.
1. Menu -> Settings -> Defaults
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.
