中文摘要：
提出一种基于能量阈值的评估钢筋混凝土柱竖向剩余承载力的损伤准则。该损伤准则是单步能量阈值与总滞回耗能的线性组合,能反映能量阈值与总能量相互耦合的影响。对振动台试验的数据、拟静力试验数据和数值算例进行了模拟分析,结果表明,基于能量阈值的损伤准则能很好评估各种工况下钢筋混凝土柱竖向剩余承载力,可用于建筑和桥梁结构地震作用下失效路径分析。
英文摘要：
An energy threshold based damage criterion is proposed to evaluate the axial residual strength of RC columns.The damage criterion is a linear combination of one-step energy threshold and the total hysteretic energy,which can also reflect the coupling effect of them.The shaking table test data,pseudo-static test data and a numerical example are analyzed,and results indicated that the proposed damage criterion can evaluate the residual strength of the RC columns on almost all kinds of conditions,which can be used to analyze the failure path of buildings and bridge structures under seismic excitations.
