Modal Analysis on the Multi-layer Frame Structure Based on ANSYS

Chen Zhao-y

Abstract

By using large finite element analysis software ANSYS,this paper makes the modal analysis on a 11-floor frame structure,calculates respectively the natural vibration periods of pure frame system and frame-shear wall structure under different conditions,and analyzes the influences of different factors on the frame structure's period reduction factor.
