Title: Mechanics of Tall Building Collapse Under Earthquake Excitation

Abstract: This seminar will examine the nature of collapse of one class of tall buildings (steel moment frame buildings) under earthquake excitation. Using a parametric analysis of a couple of index buildings subjected to idealized ground motion histories, the ground motion features that cause collapse in these structures is established. Systematically mapping damage localization patterns allows tracking of the evolution of the collapse mechanism. It is then possible to demonstrate the existence of a select few preferred mechanisms of collapse in these buildings and describe the associated physics using wave propagation through a shear beam. Finally, a simple theory based on energy principles that can identify these mechanisms is presented.

All are welcome to attend this seminar.
