Calculations

Is it possible to calculate the Ucw value with WINISO®?

With WINISO® you can calculate all the detailed values of the façade (U-values of profiles, Psi-values of glass edge, Psi-values of all-glass corner, Psi-values of jamb door transition, etc. pp.), as well as isothermal curves of the connections. The values determined in this way are then added together in terms of area and length for a Ucw calculation and related to the total area of the façade. The latter is usually done with Excel or other tools.

How do I calculate a Uw value with a rain track?

In principle, 2 Uf values are calculated – side/top and bottom with rain rail.

How can the proof of equivalence be calculated for the example shown According to DIN EN ISO 4108 Supplement 2?

The mathematical proof of equivalence is carried out with the Psi-value and frsi-value calculation. The calculation is based on the standards DIN EN ISO 10077-2 in conjunction with DIN EN ISO 10211. The frsi value is calculated according to DIN EN ISO 4108-2.

Which settings have to be changed if the "convergence requirements" are not achieved?

The error message appears if the drawing has very small geometries in seals or corners. For this, increase the number of passes and the number of calculation runs depending. First increase the max. number of passes to 2. Also check whether any small surfaces in the drawing can be combined or deleted.

How are isotherms displayed in the printout?

In order to display the curves in the printout, you must show the isotherms in the “Evaluation” tab after your calculations by clicking on the icon marked in red.

How to edit the rectangle for the assignment of indoor or outdoor air ?

In the program, select “Options”, “Settings”. In the window you can now edit the rectangle under “Areas”. In your case you would have to check the boxes “Top” and “Bottom”.

How to apply the line function?

You can only draw individual lines in the CAD tab, a line is dropped with the Enter key. From the Project tab onwards, you can no longer draw individual lines with the “Draw polyline” function, but only closed polygons or areas.

I cannot find the material "Adiabat" in the material selection list in WINISO®.

The “material” Adiabat is ALWAYS in the material drop-down menu and in the project in the context menu with right mouse button

Can wfe files be converted to the old format?

The WinIso formats are not backwards compatible. This means that wfe files from the new WINISO® cannot be read in the old WinIso2D.

Is it possible to model the temperature in the panes due to solar radiation with WINISO®?

In WINISO® you set the absorption as “area power” in W/m² on a surface of a material (boundary condition on edge).

The result doesn‘t show different angles, but you can help out with a simple method.

Further information:

What is the difference between the Uw-value and the U-value and where is the U-value defined for a glazing?

The Uw-value considers the whole window. If you just take the glass, you define the U-value just for the glazing without the frame.

The Uw-value includes the frame, glass and also heat bridges.

The U-value is just a coeffizient for the glass.

Which values are used for the different deposited float glass?

The values for the deposited float glass are original spectral data from the suppliers.

Is it possible to export glazings to a *.spc –file, or to see transmission/reflection of the different wave lengths as values and not in the graphical curve?

The export of *.spc –files and publishing the spectral data values is not allowed by us. We guarantee the producers to keep their spectraldata. Software users are not allowed to extract those informations. If you need spectral informations, please contact the producer.

The impoft of *.scp-files is possible in WINSLT®

WINSLT® schows a window where only allowed combinations are visible. Now I can insert the different objekts. A calculation can not be executed, but the producer actually produces a coating on the given layer.

We got the combination rules from the several producers and can’t change them by ourself.

We allready sent a request to the producers to check the given data. If we receive changes, this will be changed in the next software update

WINSLT® Standard

I need a template Excel file for importing a special glass, so that the import work properly and without any problems. How can the spectral data of particular glazing be imported?

Instructions for the calculation of the load-bearing resistance Rd can be found in the instructions below.

The lower/innermost pane of an insulating glazing in horizontal installation (e.g. 30°) should have safety devices in order to be able to absorb the entire loads of the upper pane(s) in the event of glass breakage. Is this case integrated into GLASGLOBAL's background calculations?

The “Break” load case is integrated into GLASGLOBAL’s calculations.

For further information, please refer to the document below.

How are the load shares on the individual panes of insulating glass calculated and can these be specified in the printout?

The load components are calculated according to DIN 18008 or secondary literature from the standard.
It is not possible to output them individually.

Yes, the header and footer of the printout can be adjusted. This also includes the possibility of depositing a logo. Instructions on how to do this are given below.

The load components are calculated according to DIN 18008 or secondary literature from the standard.
It is not possible to output them individually.

Sample calculation

In the following instructions you will find a sample calculation for a vertical double insulating glazing with an all-round linear bearing and a dimension of 2000 mm x 850 mm.

What amount must be set for the line load?

The line load is regulated in EN 1991-1.

For more information on the line load, see the information below.

The program provides an indication that the detection of deflection could be omitted. Does this mean that the glass can be used even if proof has not been provided?

Yes, DIN 18008 allows for some exceptions.

See below for more information:

What are the specifications for the calculation in GLASGLOBAL®?

GLASGLOBAL® is a software for the static verification of single and insulating glass. Based on DIN 18008 and the concept of partial safety factors, the risk of breakage and the deflection of glazing under load from wind, snow, climate fluctuations, differences in altitude and traffic loads are determined. Optionally, the membrane stress effect can be taken into account for discs mounted on all sides.

What are the functions of the proposal module?

For glass thicknesses, the degree of utilization of different glass thicknesses is displayed. The number of discs and the geometry are not changed. The size matrix shows the different degrees of utilization for different dimensions of the pane. The glass structure and the loads are not changed here, only the dimensions for width and height.

How can I print the information from the proposal module?

You will find instructions below.

Can GLASGLOBAL® also be used for calculations for conservatories or post-and-beam glazing?

Yes, this is possible with GLASGLOBAL®, please find instructions below.

On which layer is the sun and heat protection located?

The coating is marked with an asterisk on the respective layer.

Why is a line load specified although no load has been entered in the "Line load" tab?

In GLASGLOBAL ALL load combinations are always calculated and output which are theoretically possible and could be decisive. This is also the case if a load = 0. Since Gamma*Psi*0.00 naturally returns 0.00, this load is not included in the calculation of deflection and stress, but the combination of the other loads may be decisive.

How is the modification coefficient kmod in GLASGLOBAL® taken into account and can it be changed?

The modification coefficients are regulated in DIN 18008 Part 1.

In DIN 18008-1, the modification coefficients kmod for thermally non-preloaded glasses are defined as a function of the exposure time. These are specified in Section 8.3.7:

  • permanent effect kmod= 0,25
  • average exposure time kmod= 0.40
  • short exposure time kmod= 0.70

You can also enter your own values. These then appear in red and no longer comply with the standard specifications. The “Default values” button can be used to reset the values in accordance with the standard settings.

How do Rd values come about?

The Rd values are based on the fk values (charct. strength, N/mm2) e.g. of 120 for ESG and 75 for ESG enamelled to DIN 18008 (see preset values under Settings). Depending on storage or use in laminated safety glass etc., however, there are also various factors – in addition to the partial safety factors gamma.

It must be ensured that monolithic ESG panes are not permitted for point-fixed vertical glazing and that these are not even calculated in GLASGLOBAL. It must always be laminated safety glass from ESG or TVG.

Are the data updated by the listed suppliers?

The product data is compared with the manufacturers at regular intervals (quarterly) to ensure that it is up-to-date with regard to new or obsolete products and updated in the program. For some products from the manufacturers’ portfolio (especially coatings with special, consulting-intensive properties) the manufacturers do not want to pass on technical details without consulting the user/processor and do not make them publicly available for WinSLT.

In this case, you, or your customer, contact the manufacturer directly to get spectral data. You may also be able to find the spectral data in the WIS database, export it and import it into WinSLT.

How can I export calculation files from GLASGLOBAL or import them to another workstation?

In GLASGLOBAL you will find the program menu “Import/Export” with these program functions you can export and import calculations.
Please find detailed instructions below.

GLASGLOBAL® Standard (DIN 18008-1+2)

How can a possible snow accumulation be calculated for horizontal glazing?

To do this, activate the option “Glass installed in the lower part of the building” in the wind and snow load window under “Component/ Roof”. In addition, the geometry data of the main roof must be entered.

This ensures that drifts and snow from the main roof are taken into account.

What does the "res.SZR=0" on the printout mean?

“res. SZR = 0” means that in a certain LF combination the deflections are so high that the panes touch each other, i.e. the “resulting space between panes” is 0.0 mm.

How is it possible to define manually defined load cases?

If you define your own load cases under “Load combinations” in addition to the existing load cases, these are also specified in the printout with the same sequential number as under “Load case definitions”. When defining your own LF, the desired Psi values must of course be defined, as otherwise the load x gamma x Psi = 0 results.

Is the "serviceability (deflection mm) f" as a result taken from the centre or edge of the pane?

DIN 18008 and thus GLASGLOBAL assume sufficiently rigid supports and the deflection is determined accordingly for the centre of the pane. In the case of double-sided discs, this is of course equal to the edge of the disc.

How is a three-sided glazing calculated?

Glazing mounted on three sides is calculated like glazing mounted on two sides (in the Standard and Crash module).

If a glazing in the point bracket module is calculated and “Three-sided” storage is selected, the FEM core calculates the utilisation for the actual, three-sided storage (for single glazings).

It is possible to enter single panes with a thickness of 2mm into GLASGLOBAL®. Are 2mm glasses also allowed according to DIN 18008?

DIN 18008 regulates glazing with single panes between 3 and 19 mm thickness. 2 mm panes can be entered and calculated on request by some customers. DIN 18008 allows thinner glasses to be calculated with the values of a general test certificate issued by the building authorities.

Does GLASGLOBAL® also provide information on the dimensioning of the support / storage of the glass?

GLASGLOBAL® calculates the static proof of the glass according to DIN 18008 with the load assumptions according to DIN EN 1990 and 1991 – 1-3/-4. A proof of the holding construction of the glass is not part of these standards and therefore not contained in GLASGLOBAL®.

How is the verification facilitation tested in the program?

The test whether a static verification can be omitted is carried out in accordance with DIN 18008 Part 2, Section 7.

Please refer to the instructions below for detailed information on simplification of verification.

Can a simple one-sided linear calculation also be performed (e.g. clamped railings)?

Yes, you can easily perform one-sided linear calculations with GLASGLOBAL.

Instructions on how to do this are given below.

Is it possible to calculate a barrier clamped at the bottom with vertical load?

Yes, this is possible in the GLASGLOBAL® Standard module.

To do this, select a vertical glazing in the geometry and store an installation angle of 90°. Now set the bearing support to “clamped at the bottom”.

Where to enter the roof pitch for the roof panes in GLASGLOBAL®?

To back up the roof pitch of your roof panes, go to the geometry. Select the “Horizontal glazing” and set the “installation angle”.

GLASGLOBAL® Point-fixed (DIN 18008-3)

Is it possible to calculate point holders smaller than 50mm with the module?

No, DIN 18008 Part 3, 5.3 only permits a radius >= 25 mm.

Kann man mit dem Modul Punkthalter auch kleiner als 50mm berechnen?

Nein, die DIN 18008 Teil 3, 5.3 lässt hier nur einen Radius >= 25 mm zu.

GLASGLOBAL® Walk-on (DIN 18008-5)

Is the shear modulus of GLASGLOBAL® also integrated in the Walk on module?

No, because the shear modulus only works for 2-fold laminated safety glass and at least 3-fold laminated safety glass must be used for the walkable panes.

GLASGLOBAL® Accessible (DIN 18008-6)

Do the calculations with GLASGLOBAL® Accessible (DIN 18008 Part 6) replace a comparison report for the residual load capacity?

In GLASGLOBAL® “Accessible” the calculated proof of impact resistance and residual load capacity is carried out in accordance with DIN 18008-6, Appendix B. If this verification is fulfilled, an experimental verification/comparison report is no longer required.

Membrane stress

According to which formula/ literature/ table is the membrane stress determined?

The basis of the calculation models is the cooperation in the standards committee CEN TC129 WG8, documented in “E DIN EN 12474-2:2000Glass in Construction – Dimensioning of Glass Panes, Dimensioning for Uniformly Distributed Loads”.

The results of the calculation of a project with and without membrane stress do not change. What is the reason for this?

The membrane tension effect is most effective on large format discs with an almost square geometry. For small formats, the effect of membrane stress is zero.

In the case of rectangular vertical glazing (linear mounted on the reverse side, no consideration of the shear bond for laminated safety glass, category A), the design is only fulfilled for some glass formats if the membrane stress is taken into account. Now GLASGLOBAL® stands "only for area load", which is not the case for category A (line load 1kN/m). Can the membrane stress also be applied to the line load by category A?

Yes, the membrane stress can be taken into account.

For detailed information on how to apply the diaphragm stress, please refer to the instructions below.

When may the membrane stress be applied?

The approach of the diaphragm stress is limited to linear bearings, area loads and rectangular discs on all sides. There is no distinction or restriction between horizontal and vertical.

Sound-database

How can products be recorded that are not stored in the sound database?

You can save your own superstructures in the sound database and supplement the sound values.

How does the calculation of a structure with the acoustics database work?

The acoustics database is searched for data on the current structure or a similar structure.

Own superstructures can be stored in the acoustics database, and the sound values can also be supplemented.

Do the data of the products stored in the sound database come from different suppliers?

Currently, the products stored in the sound database are only available from UNIGLAS GmbH & Co KG.

Further suppliers have already agreed to store their products in the sound database.

Wind and snow load

If insulating glass is used at the edge of a house, a wind load surcharge of factor 1.7 or 1.4 applies. Where in GLASGLOBAL® can this surcharge or the position of the window in the house be taken into account?

According to DIN 1055 and EN 1991, surcharges do not apply directly at the edges, but rather the exact position of the pane in the wall or in the roof is taken into account. For the
Different cp values are defined for different layers/areas. These result in
the program by defining the building geometry and the position of the pane
in the building in the wind and snow load module. This can be operated under “wind and snow load”. In the demo version, however, this module is deactivated and set tomanual entry is preset.

How are the building dimensions, wind areas and installation heights taken into account?

In the “Wind/Snow load” menu item, you can make precise entries for determining the wind load in the subitems.

Refer to the instructions below for more information.

How are the load assumptions for Switzerland treated?

The loads are stored in GLASGLOBAL® according to SIA or manually. This requires the “GLASGLOBAL® Snow Load Switzerland” add-on.
