Abstract
the nonlinear behavior analysis of through-story columns under earthquake is of great significance for improving the seismic perform-ance of building structures.Based on time history analysis and pushover analysis,the deformation characteristics,stress distribution and dam-age mode of through-story columns under different earthquake intensities are discussed,the results show that the stress concentration and plas-tic hinge are easy to occur in the through-story column under the earthquake action,and the damage zone is easy to form at the bottom and top of the through-story column with the increase of the earthquake intensity,and the obvious nonlinear behavior appears,based on the analysis re-sults,some suggestions on seismic design of through-story columns are put forward to provide reference for engineering practice.关键词
