摘要
由于自重轻、抗震性能好等优点,钢结构直接在混凝土结构上加层,正越来越多的应用到实际工程中.加层后形成的混合结构由于原结构和加层结构采用不同的结构形式,存在质量和刚度的突变,从而柱脚刚度将影响结构的整体性能.结合工程实例,采用有限元分析程序从层剪力、层间位移等方面比较分析刚性柱脚和半刚性柱脚对结构抗震性能的影响.
Adding steel layer on the top of the concrete structure is widely used in practice due to its advantages of lightness and good anti-seismic properties. However, because of the structural difference between the adding layer and the matrix, the stiffness of column base may cause influences on the structural behaviors. In the present paper, based on a practical project, a finite element analysis method is employed to analyze the anti-seismic structural behaviors with rigid c r semi-rigid column base influences.
