摘　　要：在经典Park损伤模型的基础上纳入时间因素,建立动态损伤模型.采用HRB400高强钢筋混凝土柱抗震试验得到的参数数据,建立用于弹塑性时程分析的恢复力模型.对单自由度体系的地震反应进行模拟,将时间因素纳入到损伤评估模型中,模拟构件的损伤演化过程,得出在不同地震波输入下,相同构件损伤趋势均是逐渐增大的,但增大的幅度和规律不一样.Based on the Park damage model considering time factor, the dynamic damage model was established. Using the data of the seismic experiments of HRB 400 high strength reinforced concrete columns, the restoring force model was built for the elasto-plastic time history analysis. The seismic response of single freedom system was simulated, considering time factor in damage model. The evolvement of component damage was carried out. It is concluded： inputting different seismic wave, the damage degree of the same component increases gradually, but the magnitude of damage degree is different.
