Structural Analysis of Slender Glass Panel Subjected to Static and Impact Loading

Abstract

Slender glass panels are widely used as storefronts and indoor separating walls in shopping malls and public buildings. To ensure that the design and construction is technically safe for general use and that it meets current and accepted technical standards, in-situ testing is required by the building administrator or authorities. A case study was performed of an indoor glass lantern in a public building made from slender two-side supported glass panels with a complex geometry. It provides structural assessments and results of in-situ experiments including static loading and soft body impact test. Results from numerical simulations of impact loading on the glass panels complementing the experimental results are also presented. The in-situ testing proved that the structural design meets current standards regarding the static loading. The soft body impact test proved the safety of the intact panel and the panel with one ply deliberately broken. The numerical study showed that, for a more complicated geometry, the stress distribution can dramatically change over time and that stress concentrations can develop at certain locations at a late stage in the impact history.
