Seismic Design: Conventional vs. Capacity Design

This lecture covers the seismic design of structures, focusing on conventional design and capacity design. It explains the typical failure modes of structures during earthquakes, estimation of peak forces and displacements, and the design of new buildings with reinforced concrete walls. The instructor discusses the principal idea of capacity design, failure modes of RC walls, and the behavior of concrete and steel. The lecture also delves into the seismic design objectives of SIA-codes, two different design approaches in SIA 261, and the behavior of conventionally-designed structures under seismic effects.
