Abstract

The P-delta effect defined as a second order effect occurs on any structure displaced by lateral forces, such as seismic or wind force. The impact of extra vertical loads including gravity will cause additional moments on the deformed structure leading to further displacements. The purpose of this study is to investigate the P-delta effect on multi-story steel framed structure with different distributions of same amount of total vertical load setting conditions, symmetrically and unsymmetrical. Meanwhile computer models with finite element analysis method will be used for this study.
