The Importance of Building Joints and Separation in Seismic Events

This chapter explores the significance of building joints, particularly seismic joints, in preventing structural damage during seismic events. It discusses the history of using joints in complex buildings, the impact on building separation and drift limitations, and the potential damage caused by misalignment of floor diaphragms. The chapter also touches on the challenges faced by building owners in upgrading older buildings and the need for seismic design regardless of wind loads.
