Although building envelope systems are normally designed or specified as nonstructural components, not intended to take part in lateral load resistance, past earthquakes have shown that these components are vulnerable to damage. In this chapter, initially some of the different types of damage sustained by envelope components in past earthquakes are described. This is followed by an explanation of racking behaviour of cladding panels. Then an overview of some recent studies involving development of innovative solutions to mitigate seismic damage to building envelopes is presented. Finally, the chapter discusses building code seismic provisions and some design guidelines for building envelope systems.
