【摘要】 <正>一、引言钢管伴以高强混凝土组合形成的钢管混凝土结构在高层建筑中得到日益广泛的应用, 钢管混凝土框架剪力墙结构以其广泛的适应性以及良好的抗震性能成为常用的结构形式。钢管混凝土框架柱与梁之间的连接既非完全刚性,又非理想铰接,在荷载作用下都会表现出一定程度的半刚性。半刚性连接使得钢管混凝土框架剪力墙结构与普通钢筋混凝土框架剪力墙结构有着明显的不同。半刚性连接减小了钢管框架的层间抗推刚度,使得结构的水平位移加大。而且由于钢管混凝土框架刚度的改变,结构刚度特征值λ也随之发生变化,更多还原

【Abstract】 ANSYS is employed to model the semi-rigid concrete filled steel stub frame-shear wall structure. The effects of the semi-rigid connection on some characters are brought to light, as the natural periods, drifts, moment and shear of the shear wall, shear of the frame and so on. The results show that semi-rigid connections tend to increase the natural period. However, the effect on higher modes is negligible. The study also indicates that connection flexibility tends to increase drifts, moment and shear of the wall but reduce the shear of the frame. Design suggestions on considering the semi-rigid connection have been proposed. The proposed methods may supply references for the engineers.更多还原
