Investigation of Seismic Pounding Effect on Symmetric 10 Storey Reinforced Concrete Buildings Using SAP2000
Abstract: ABSTRACT Earthquakes have historically been responsible for significant structural failures, often resulting in substantial economic losses and endangering human lives. One notable failure mechanism observed during seismic activity is seismic pounding, which occurs when adjacent buildings collide due to insufficient separation gaps. This phenomenon is particularly concerning in densely populated urban areas where space constraints often prevent the provision of adequate clearances between structures. Such impacts can lead to severe …
