Load Bearing Behaviour of Laminated Glass Under Static and Dynamic Load

Dr. Norbert Wruk, Prof. Dr.-Ing. habil. Albrecht Schutte, Dr.-Ing. Werner Hanenkamp

Although the increased rigidity of laminated
glass is widely recognised, the regulations in
many countries do not allow to take into account
the shear strength of laminated glass while
designing the glass thickness. On the other hand,
it is economically important to determine the
optimum glass thickness for a given application
depending on the expected load. Therefore, the
behaviour of laminated glass under static and
dynamic loads has been examined systematically
between room temperature and 60°C. It could be
shown that laminated glass is significantly more
rigid than two single glasses of equal thickness
without any coupling. The dependence of the
rigidity on temperature and load duration was also
determined. A simplified method of designing
the thickness of laminated glass using a load
depending shear strength is proposed. [1]
