基于弹性能的结构地震损伤评价方法

摘要

Better than conventional evaluation of seismic damage model,a new calculation index of seismic damage is introduced,based on the relation between elastic energy and structure damage.The new method of seismic damage evaluation can evaluate the specimen,which was combined with the experimental data of four reinforced concrete columns.Moreover,based on the destructive test of four reinforced concrete columns and two frames,the model matches the experimental phenomena very well,a new method for seismic performance and design.%针对常见地震损伤评价模型的不足，基于弹性能释放与结构损伤的内在关系，推导出新的地震损伤指标计算表达式。基于此，结合4根钢筋混凝土柱的试验数据，建立了构件地震损伤评价新方法。通过4根低周反复荷载破坏试验柱和两榀框架结构数据的验证，本文提出的地震损伤评价模型得到的结果与试验现象非常一致，为结构抗震与设计提供了一种新的思路。
