钢管混凝土框架-剪力墙结构的抗震性能分析
|
摘要
针对钢筋混凝土剪力墙对钢管混凝土框架结构的抗震性能影响,采用SAP2000有限元软件对12层钢管混凝土框架-剪力墙结构进行模态分析和地震响应弹塑性时程分析,并结合12层钢管混凝土框架结构进行分析比较。结果表明:在不同地震波作用下,钢管混凝土框架-剪力墙结构的层间最大位移,层间最大位移角,水平向绝对加速度峰值等数值均小于钢管混凝土框架结构的数值,数值分析表明钢管混凝土框架结构能与钢筋混凝土剪力墙很好地共同作用,表现出较好的抗震性能。
Focusing on seismic behavior of concrete-filled steel tubular frame structure considering reinforced concrete shear wall,the finite element analysis software SAP2000 is used to analyze conduct modal analysis and seismic response elastic-plastic time history analysis of the 12 layers structure of concrete-filled steel tubular frame-shear wall and the results are compared with 12 layers structure of concrete-filled steel tubular frame.The results showed that the maximum displacements,the maximum relative storm displacement angle,the peak horizontal acceleration,and the bottom shear force of the concrete-filled steel tubular frame-shear wall structure were less than those of the concrete-filled steel tube frame structure under the function of the different kinds of seismic waves.The concrete-filled steel tubular frame structure cooperated well with the reinforced concrete shear wall and exhibited excellent seismic performance.
