How does a glass facade support seismic performance requirements in earthquake-prone regions?

Question

Accepted Answer

Glass facades in seismic zones require flexible design to accommodate building movement. Engineers use flexible anchors, sliding connections, and structural silicone to absorb seismic forces. Laminated glass is preferred because it remains intact even when cracked. The façade system must undergo seismic racking tests to simulate lateral displacement. Mullion splicing and joint design allow controlled movement without glass failure. By designing with sufficient tolerances, the façade reduces the risk of falling glass during earthquakes. Seismic design ensures occupant safety and minimizes post-event repair needs.
