Seismic Analysis Based on IBC 2003 (Equivalent Lateral-Force Procedure, ASCE 9.5.5)

Seismic analysis is a tool for the estimation of structural response in the process of designing earthquake resistant structures and/or retrofitting vulnerable existing structures. In principle, the problem is difficult because the structural response to strong earthquakes is dynamic, nonlinear and random

The Equivalent Lateral Force Procedure (ELFP), as outlined in ASCE 7, is a method for developing and distributing equivalent static lateral loads on a structure to account for the horizontal seismic load effect
