LATERAL DRIFT OF REINFORCED CONCRETE STRUCTURES SUBJECTED TO STRONG GROUND MOTION.

Abstract

A simplified method is described for estimating lateral drift of reinforced concrete structures subjected to strong earthquake motion. The method is modeled after spectral-response analysis with simplifications based on observed characteristics of nonlinear dynamic response of reinforced concrete structures. Its application is limited to the types of structures and ground motions considered in its development. However, the method can be readily calibrated for other types of structures or modified for different foundation conditions.
