弹性变形能形式的地震损伤评价模型

Seismic Damage Assessment Model of Form of Elastic Deformation Energy

针对典型地震损伤评价模型存在的缺陷,通过将地震复杂的滞回过程进行简化,提出了一种弹性变形能形式的损伤评价模型;重点阐述了典型的Park地震损伤评价模型以及基于延性系数的地震损伤评价模型,并根据试验数据对这3种模型进行了对比分析。结果表明,新建模型以其正确性与合理性克服了典型地震损伤评价模型的缺陷。

Aimed at the defects of the classic seismic damage assessment model, a model based on form of elastic deformation energy was proposed and the models based on the classic park seismic and the ductility were listed. Taking the complexity of the hysteretic process into account, the hysteretic process was changed into the static state based on the simplification of skeleton curves. Then, a new seismic damage evaluation model was built from the point of energy. According to the data from destructive experiments of four columns, comparisons were executed among the three models. The results show that the new model which is corrective and feasible can overcome the defects of the classic seismic damage assessment model.
