［摘要］半刚接钢框架内填钢筋混凝土剪力墙结构（PSRCW）是一种新型组合结构体系，我国《建筑抗震设计规范》（GB 50011—2010）尚未建立其性态目标。为提出PSRCW结构在不同地震水准下的性态目标，结合我国抗规给出的地震水平和结构性态水准，根据结构性态水平与损伤指数的关系，利用修正的Park-Ang损伤模型对已完成12榀PSRCW结构试验数据进行了统计分析，建立了以层间位移角表征的PSRCW结构性态指标，研究成果可为完善PSRCW结构基于性态的抗震设计方法或进行PSRCW结构地震易损性评估提供参考。

Abstract:Partially-restrained steel frame with RC infill wall (PSRCW) is an innovative composite structure system, and the performance objective of this structure at the different earthquake level do not specified in Code for seismic design of buildings(GB 50011—2010). In order to propose the performance objective of this innovative composite structure, combined with the earthquake level and structural performance level specified by Chinese seismic code, and based on the relationship between structural performance level and damage index, data of twelve previous PSRCW test specimens was analyzed based on the modified Park-Ang damage model. The performance indices represented by inter-story drift ratio  of PSRCW at the each performance level were developed, and the results can provide some useful reference for improving the performance-based seismic design method and carrying out the seismic fragility analysis of PSRCW structures.

Keywords:steel frame; RC infill wall; inter-story drift ratio; performance objective
