随着高层建筑的逐渐加高,结构的抗震性要求也越来越高。钢管混凝土框剪结构以其很好的抗震性能被广泛应用于高层框剪结构中。本文以有限元分析软件SAP2000建立半刚性钢管混凝土框剪结构的有限元模型,对比分析了梁柱为刚接、铰接、半刚性连接时对钢管混凝土框剪结构的周期、位移、内力的影响。结果表明：半刚性连接使结构的自振周期变大,随着振型的增大半刚性连接对自振周期的影响越来越小;半刚性连接使得框架的剪力有所减小。半刚性连接减少了钢管框架的层间抗推刚度,使得结构的水平位移加大。
隨著高層建築的逐漸加高,結構的抗震性要求也越來越高。鋼管混凝土框剪結構以其很好的抗震性能被廣汎應用于高層框剪結構中。本文以有限元分析軟件SAP2000建立半剛性鋼管混凝土框剪結構的有限元模型,對比分析瞭樑柱為剛接、鉸接、半剛性連接時對鋼管混凝土框剪結構的週期、位移、內力的影響。結果錶明：半剛性連接使結構的自振週期變大,隨著振型的增大半剛性連接對自振週期的影響越來越小;半剛性連接使得框架的剪力有所減小。半剛性連接減少瞭鋼管框架的層間抗推剛度,使得結構的水平位移加大。

With the gradually increasing the height of high-rise building structures seismic requirements are also increasing.Concrete filled steel tubular frame-wall structure with its very good seismic performance has been widely used in high-rise frame-wall structure.In this paper,finite element analysis software sap2000 establish semi-rigid steel concrete frame-wall structure of the finite element model,comparative analysis of the beam is rigid,articulated,semi-rigid connections for concrete filled steel tubular frame-wall structure of the cycle,displacement,force of impact.The results showed that： the structure of semi-rigid connections to the larger natural period,with the increase of modal semi-rigid connections on the natural period of smaller and smaller;semi-rigid connections makes the framework of the shear decreased.Semi-rigid steel frame connection to reduce the resistance to push the layer stiffness,making the structure of the horizontal displacement increased.
