Glass calculations


IBS regularly conducts glass calculations based on the Eurocodes (NEN-EN 1990 – Basis of structural design). For the application of glass, it is necessary to validate the occurrance of maximum tensile bending stresses and deflections, as a result of the various loads.

Sample Projects

Some recent projects for which IBS has conducted static calculations of the glass are:

  • Municipal Office + Railway Station – Delft NL
  • Officebuiding Valina – Amsterdam NL
  • Officebuilding Exact – Delft NL
  • Officebuilding European Patent Office –Rijswijk NL

SJ Mepla

Non rectangular geometries can not be calculated using tables or simple formulas; they require the use of finite-element calculation methods.

IBS can offer glass calculations using SJ Mepla; a finite-element computer program for structural glass calculations . With this software package, calculations can be conducted to determine the tensions and deformations in the plate-like structures under different loads.

Besides glass calculations IBS also performs various other structural calculations of components of the facade construction such as balusters, (frame and / or curtain wall) profiles and aluminum and / or steel plates.
