Simplified analysis of asymmetric buildings subjected to lateral loads

Abstract

A simple procedure is presented for lateral load analysis of asymmetric buildings, taking into account the coupling between the lateral and torsional components of response. Bending rotations of the vertical members are taken into consideration and these are made proportional to the stiffnesses of the members resulting in an analysis with 5n degrees of freedom for a building with n storeys. The entire analysis is conveniently programmed and gives quick results on a microcomputer. Numerical examples pertaining to both static and free vibration analyses are presented and the results are in good agreement with those from a comprehensive package program. © 1992.
