Load Bearing Performance and Breakage Response of Laminated Anticlastic Cold Bent Glass Plates

Abstract

Anticlastic cold bent glass plate plays a significant role in the design of free-form glass facades. Residual stresses will be introduced in the plate during the cold forming process which may influence the subsequent load bearing capacity. Current research on load-bearing performance of anticlastic cold bent glass plates primarily focuses on the influence of support conditions, cold bending degree, and load patterns. However, effective support conditions for post-cold-bent loading have not yet been determined, and effective failure criteria have yet to be established. In this paper, a series of load bearing tests have been conducted to explore the mechanical properties and failure mechanisms of anticlastic cold bent glass plates. Then, the effective finite element models have been built to systematically investigate the effects of support conditions, cold bending extent, width-thickness ratio and aspect ratio.
