轴压比对钢管混凝土边框组合剪力墙的影响

The impact on composite shear wall with concrete filled steel tube columns in different axial-load ratio

介绍了钢管混凝土边框组合剪力墙是一种适用于高层及超高层建筑的新型组合剪力墙,轴压比是影响剪力墙受力性能的一个主要因素,设计了5个具有不同轴压比的试件,进行了有限元分析,研究表明随着轴压比的增大,钢管混凝土边框组合剪力墙的延性逐渐降低,屈服荷载也逐渐减小。

It is introduced that composite shear wall with concrete filled steel tube columns is a new kind of composite shear wall,which is applicable to high and super-high buildings.Axial-load ratio is one of key points to shear wall for behavior.It is designed five test pieces with different axial-load ratio and makes the finite element analysis.The results show that： with the axial compression ratio increasing,the steel frame shear wall concrete ductility gradually reduced,the yield load is gradually reduced as well.
