钢筋混凝土柱地震损伤模型
Seismic damage model for reinforced concrete columns
摘要
Abstract
In view of the problems that the calculation results are divergent,and the damage index and the failure phenomena are not completely consistent,existing in the seismic dam-age models of reinforced concrete columns,on the basis of existing seismic damage models and reinforced concrete column test,a more precise double-parameter damage model based on stiffness degradation and hysteretic energy dissipation in consideration of the influence of loading path is proposed.This paper puts reinforced concrete columns test of PEER database executed by Kunnath as the research object,the damage index of several common models and proposed model are calculated and compared with experiment phenomenon.The results show that proposed model has better convergence.The damage state of the columns under different loading conditions can be evaluated more accurately.The influence of loading path can be considered and the low-cycle fatigue damage under small displacement loading can be evaluated reasonably.关键词
