Glass is transparent and glass breaks. Glass can also be used structurally when it is designed correctly. This book develops 4 glass risk categories to guide appropriate safety when you need it and economy when you don’t. This manual makes it simpler for Architects to specify structural glass assemblies, discuss options with clients and explain the strategies to building departments while providing clear requirements when bidding a project. For Engineers, it provides the tools and formulas for evaluating structural adequacy of slender systems when tension stress controls the failure mechanisms. Each glass risk category defines the robustness requirements and provides parameters for performing checks in the damaged state. For Owners and Project Managers it facilitates selection of glass assemblies that meet expectations, and criteria to ensuring they are fulfilled. This book guides successful implementation of glass as a structural material in buildings, making it more accessible to all parties in building construction.
