摘　　要：综合考虑余震影响和结构损伤,提出一种基于损伤性能的消能减震结构抗震设计方法。为满足结构抵抗余震的性能要求,提出结合主余震的损伤性能目标。以Park-Ang双参数损伤模型为基础建立了结构层间损伤计算公式,通过损伤程度评估结构抗震性能,给出消能减震结构基于损伤性能的抗震设计流程。Considering the aftershocks influence and structural damage,we present a kind of seismic design method of energy dissipation structures based on damage performance. In order to satisfy the performance requirements of the structure which could resist the aftershocks,we aim at the damage performance combined with the main- aftershocks. Based on Park-Ang tw o parameters damage model,we build the structural interlaminar damage calculation formula,and evaluate the seismic performance of the structure by damage degree. Finally,we give the seismic design procedure of energy dissipation structures based on damage performance.
