为了解组合墙体-楼盖梁规程连接体系（CS）和新型连接体系（NS）的力学性能,采用ANSYS软件建立了有限元模型,并对不同轴压比下的CS体系、不同连接角钢厚度下的NS体系进行了低周往复加载模拟,得到了两类体系的骨架曲线、承载力特征值等结果。结果表明：轴压比增加,CS体系承载力降低,且降幅增大,延性系数减小;连接角钢厚度在0.8～2倍墙架柱构件厚度范围内时,角钢厚度增加,NS体系承载力提高;其中角钢厚度为1.2～1.5倍的墙架柱构件厚度时,体系延性系数有最大值;当角钢厚度超过2倍墙架柱构件厚度后,体系承载力变化不大。

英文摘要：

In order to know the mechanical properties of the regulation connecting system（ CS） and new connection system（ NS） of composite wall-floor beam,finite element model is built with ANSYS software,CS with different axial compression ratios and NS with different thickness of the connecting angle are simulated under low frequency cyclic loading,and the skeleton curve and the bearing capacity characteristic value of this two types of system are obtained. The results show that： with the increase of the axial compression ratio,the bearing capacity of the CS system is decreased with bigger decreasing amplitude and the ductility coefficient is decreased; when the thickness of connection angle is in the range of 0. 8 ~ 2 times of the wall frame column thickness,the angle thickness is increased,and the bearing capacity of NS system is improved; especially when the angle thickness is1. 2 ~ 1. 5 times of the thickness of wall frame columns,the ductility coefficient has the maximum value; but when the thickness of angle is more than 2 times of the thickness of wall frame columns,the bearing capacity has no obvious changes.
