Glass-aluminum façade systems, especially unitized curtain walls, are commonly used in high-rise buildings for their flexibility and aesthetic openness. However, the glazed surfaces of buildings suffer from severe brittle fracturing and posing a glass failure risk, particularly with regard to façade partitions; these pose significant issues when subjected to seismic forces. This thesis seeks to explore the numerical approach for evaluating the seismic performance of these systems. This study is based on the “Influence of Design Variables on Seismic Performance of Unitized Curtain Walls: A Parametric Experimental Study” by Bianchi et al. (2024) in collaboration with Permasteelisa Group and TU Delft, which analyzed inter-story drift imposed onto full scale glazing units.
