为研究新型RCS组合结构的抗震性能，采用sap2000有限元软件对新型RCS组合结构进行了非线性地震反应分析，并将分析结果与组成新型RCS组合结构的核心构件-焊接环式复合箍筋约束高强混凝土柱的拟静力试验结果进行了比较分析。结果表明：新型RCS组合结构具有良好的抗震性能，其在地震下的破坏机制为＂梁铰＂破坏形式，并给出了建议的弹性及弹塑性层间位移角限值，建议取值为：弹性位移角限值为1／500，弹塑性位移角限值为1／50，可为新型RCS组合结构的抗震设计提供参考。
為研究新型RCS組閤結構的抗震性能，採用sap2000有限元軟件對新型RCS組閤結構進行瞭非線性地震反應分析，併將分析結果與組成新型RCS組閤結構的覈心構件-銲接環式複閤箍觔約束高彊混凝土柱的擬靜力試驗結果進行瞭比較分析。結果錶明：新型RCS組閤結構具有良好的抗震性能，其在地震下的破壞機製為＂樑鉸＂破壞形式，併給齣瞭建議的彈性及彈塑性層間位移角限值，建議取值為：彈性位移角限值為1／500，彈塑性位移角限值為1／50，可為新型RCS組閤結構的抗震設計提供參攷。

In order to study the seismic performance of a new type of RCS composite structure (NTRCSCS), the nonlinear seismic response analysis of the NTRCSCS was carried out using finite element software sap 2000 and its analyzing results were compared with the pseudo -static test results of high strength concrete columns confined by butt -welded closed composite stirrups which were the core components of the NTRCSCS.The results showed that The NTRCSCS had good seismic performance and its failure mechanism under the condition of earthquake was the "beam hinge"failure forms.Some suggestions of elastic and plastic inter -story drift ratio limit were put forward , the recommended values for elastic displacement angle limit was 1/500 and elastic-plastic displacement angle limit was 1/50 which can pro-vided reference for seismic design of the NTRCSCS .
