摘　　要：提出了型钢混凝土剪力墙结构基于位移抗震设计中的设防水准、性能水平以及性能目标。对相应状态进行了宏观描述,并对性能水平进行了量化。将型钢混凝土结构的性能水平划分为"使用良好、生命安全、防止倒塌"三个性能水平,通过统计分析提出了型钢混凝土剪力墙结构各性能水平的层间位移角限值,然后通过剪力墙结构的侧移模式求出目标位移。建立了考虑高阶振型影响的型钢混凝土剪力墙结构基于位移的抗震设计方法和流程,通过一个算例说明了设计的基本步骤。本文方法为型钢混凝土剪力墙结构基于位移的抗震设计提供了一个可供参考的思路。The performance objectives, seismic fortification levels, performance levels are suggested for displacement-based design SRC shear wall buildings. The corresponding damage states are described and performance levels are quantified. The seismic performance of steel reinforced concrete （SRC） structures can be induced into three levels： normal service, life safety and collapse prevention. The drift angle of different seismic performance level is recommended through statistical analysis. The target drift is determined according to lateral displacement model of SRC wall building. Direct displacement based seismic design method of SRC shear wall buildings by considering higher mode effect is advised. The proposed procedure is illustrated with an example.
