Investigations of cavity pressure behaviors of double-skin Façade systems subjected to blast loads

Abstract

The main function of a façade system is to provide comfort and protection to occupants inside the building. Glass façades are susceptible to severe damage due to their direct exposure to extreme loading conditions, such as blast. There is increasing popularity in the application of double-skin façade systems (DSFSs) in modern façade construction practice due to their high energy efficiency. In addition, when designed correctly, DSFSs exhibit a potentially higher capacity for blast resistance as opposed to single-layer façade systems. However, due to the complex fluid-structure interaction (FSI) between DSFSs and blast waves, there is a lack of design codes that address the structural respons..
