基于ETABS软件钢管砼板柱结构体系地震响应分析
|
摘要
利用结构有限元分析软件ETABS建立了框架-剪力墙钢管砼板柱结构分析模型,研究了钢管混凝土柱对结构地震反应的影响,地震作用在剪力墙、框架和钢管混凝土柱之间的分配等问题,并与框架-剪力墙结构的地震响应特性进行了对比。结果表明,作为新型的结构体系,框架剪力墙-钢管砼板柱结构抗震性能良好,并且动力反应层间位移低于规范中的限定值。在同样条件下,可大大减小内柱的截面面积。地震作用全部由剪力墙和边框架承担,应加强边框架设计,提高边框架的抗侧刚度。通过合理设计,在8度设防条件下,该结构形式可以略超出规范中关于结构高度的限制。
A 3D finite element model for frame-shearwall and concrete-filled steel tubular slab-column structure is formulated with ETABS structural analysis software,the seismic dynamic response,the distribution of seismic action among the shear wall,frame and concrete-filled steel tubular columns etc.are analyzed,and the result is compared with earthquake dynamic response characteristics of frame-shear wall structure.It demonstrates that the frame-shear wall and concrete-filled steel tubular slab-column structure behaves well in resisting seismic action,and the inter-story drift values could be well below the specified value.The cross section of the inner column could be substantially decreased unedr the same load condition.It could be assumed that the seismic actions is totally beard by both shear walls and edge frameworks,indicating that the edge frameworks should be reinforced to enhance the lateral rigidity.Under seismic fortification intensity 8,the structure height could be a little larger than the specified limitations through a reasonable structure design.
