摘要:
针对混凝土结构构件在地震过程中的弹性能损失现象,提出一种与弹性能损失相关的地震损伤评价模型.该模型考虑了混凝土结构构件在地震中的能量转移和刚度退化的影响,多角度地评价混凝土结构构件的损伤情况.对6根HRBF 500钢筋混凝土柱进行低周反复加载试验,考察其在地震中损伤发展的趋势和程度,并对比经典Park模型和所建立的模型的损伤评价情况.结果表明:所建立的模型具有较好的可靠性和合理性,能克服经典Park模型的部分缺陷.
Abstract:
Considering the loss of elastic energy of structural elements during earthquake,a seismic damage model is presented.The energy transfer and stiffness degradation are involved in this new model,so the damage of structure can be evaluated in various aspects.Six HRBF 500 RC columns are tested under low frequency cyclic loading.The trend and level of damage in earthquake are analyzed by Park model and new model.By comparison of the results of two models,it′s shown: the new model is reliable and reasonable and it can overcome some shortcomings of Park model.
