Performance-Based Concept for Design of Structural Silicone Joints in Façades Exposed to Earthquake

Façade failure due to seismic event represents a potential hazard to people and can cause serious damages to buildings with consequent high-cost remedial works. As a result, interest in the design of buildings and façades to resist seismic loads and displacements has increased. Current standards and...
