基于塑性耗能的震损砌体结构剩余抗震能力研究
Study on residual seismic capacity of earthquake-damaged masonry structure based on plastic energy dissipation
摘要
Abstract
This paper is aimed at the accurate evaluation of post-seismic damage to masonry struc-tures.The study is performed by taking plastic energy consumption of energy analysis as the measurement indicator,using the remaining seismic resistance index R as the post-seismic damage assessment indicator for masonry structures,and using ABAQUS softwar to perform a dynamic elastic-plastic analysis of the seismic masonry structures at different damage levels.The results show that based on the damage levels at basically intact,minor damage,moderate damage,and serious damage,the residual seismic ability index ranges present[1.00-0.95),[0.95-0.70),[0.70-0.49),and[0.49-0.00),respectively,with no regard to destruction by 0 default.The obtained R value is basically consistent with existing inter-national standards,proving that this method is effective.关键词
