Damage Assessment of Seismic Pounding Between Adjacent Structures Using Non-Linear Dynamic Analysis

Abstract

Seismic-induced pounding poses a grave concern in developing countries, particularly in regions where adherence to structural gap provisions specified by the code is lacking. Extensive research has been dedicated to investigating the profound effects of seismic pounding. This particular study aims to assess the potential damage caused by seismic pounding in the unregulated areas of Islamabad, considering the nonlinear performance levels (Immediate Occupancy, Life Safety, Collapse Prevention) of the structure. To accomplish this, a meticulous Non-Linear Time History Analysis (NLTHA) procedure is employed. Three carefully selected ground motions are utilized in this study, and their response spectra are meticulously matched with those characteristics of Islamabad. By employing this comprehensive approach, the study enables real-time modeling of the structural damage resulting from seismic pounding, offering valuable insights into the potential risks involved
