Non-Linear Analysis and Experimental Verification of Bent Glass Curtain Walls

Authors
Abstract
A Bented Laminated Glass is recently used in the high-rise building, but its design isn’t present in the curves and tables at the ASTM E1300. Therefore, it has become a need for architects to use basis for this type of glass. To the best of knowledge authors no one study the bent laminated glass in details. Therefore, in this article, experimental and theoretical results for such Non-Linear bent laminated glass panes tested under comparison loading are presented and discussed. Four Bented Glass Lites with different thicknesses were experimentally tested for failure under compression load. Experimental results were compared with finite element; FE analysis with the Abaqus program. Behavioral properties; analyzes were performed including ultimate loads, deflections, and failure modes. A numerical sensitivity analysis was performed using ABAQUS 6.14 software to find suitable element types and support conditions that the experimental model could simulate. we created a closed chamber as a support system for the test panel and glued it to the chamber with structural silicone. The internal air in the chamber was evacuated to simulate a positive pressure on the outer surface of the panel under test. A displacement transducer and strain gauge were attached to the tested system to measure the displacement and strain as the pressure in the chamber decreased. The results of the analysis were presented and discussed. The shell element is the best element capable of simulating a thin Bented glass lite. The result from this experimental study provides thesis findings for non-linear bented laminated glass for further investigations and developments on such type.
