钢骨-钢管混凝土框架结构抗震性能比较
|
摘要
运用SAP2000有限元分析软件对钢骨-钢管混凝土框架结构进行模态分析和地震响应弹塑性时程分析,并结合8层钢管混凝土框架结构和钢骨-钢管混凝土框架结构工程进行比较。结果表明:不同地震波作用下,钢骨-钢管混凝土框架结构层间位移最大值、顶层的最大层间位移角、水平向加速度峰值及基底剪力最大值均小于钢管混凝土框架结构,其抵抗水平地震作用的能力优于钢管混凝土框架结构,对地震的响应弱于钢管混凝土框架结构,对地震的迟滞作用好于钢管混凝土框架结构。
The finite element analysis software SAP2000 was used to conduct modal analysis and seismic response elastic-plastic time history analysis of steel concrete filled steel tubular frame structure,and 8-story concrete-filled steel tubular frame structure and steel concrete filled steel tubular frame structure were compared.The results show that the displacements,the maximum relative storm displacement angle of the top,the peak horizontal acceleration,and the bottom shear force of the steel concrete-filled steel tubular composite frame structure are less than those of the concrete-filled steel tube frame structure under the function of the different kind of seismic wave;and the steel concrete-filled steel tubular composite frame structure has better resistance to the horizontal seismic action,weaker response to the earthquake action and better effect to the hysteresis than the concrete-filled steel tube frame structure.
