摘　　要：以实际工程为背景,运用ABAQUS有限元软件,建立3种模型,包括YSC模型(原有三层钢筋混凝土结构)、JLC模型(加两层钢框架结构)、WBGJLC模型(外包钢加固的加两层钢框架结构),然后对以上3种结构模型分别进行抗震性能研究,包括模态分析和反应谱分析,进而研究外包钢加固节点对加层结构的影响,以及对加层结构体系缺陷的改善情况。Taking actual engineering as the background,this paper uses ABAQUS finite element software to establish three models,including the YSC model(the original three-layer reinforced concrete structure),JLC model(frame structure of adding two layers of steel)and WBGJLC model(frame structure of adding two layers of steel reinforced by outsourcing steel),then studies the seismic performance of the above three structural models,including modal analysis and response spectrum analysis,and studies the influence of the reinforcement to the joints by outsourcing steel on the adding layer structure and the improvement of the defects of the adding layer structure system.

关 键 词：加两层钢框架 外包钢加固 模态分析 抗震性能
