Stability & Resistance of Hybrid Glass Structures under Seismic & Temperature Loads

Abstract

Glass structural members usually have thinner cross sections compared with other construction materials. This raises stability and failure issues. This paper examines numerically a glass one-storey pavilion in high seismicity zone. The stability, seismic and temperature resistance of the structure depend heavily on the brittle nature and the type of glass. The structural body of the pavilion consists of moment frames assembled by columns and beams, assuming a glass diaphragm roof at the top level of the building. For each structural member a combination of different glass types is assumed in order to achieve an optimization of performance and failure pattern. A base isolation system is also considered. Proper finite element models were used to represent the composite cross sections. The combination of the different glass types, permits forming stable and resistant hybrid composite structures reaching the EC’s target safety levels, avoiding immediate collapse.
