摘要
某超高层混合结构高度193m,高宽比8.8,采用矩形钢管混凝土框架-核心筒结构体系。结构存在高度、扭转不规则、楼板局部不连续、侧向刚度不规则超限内容。分别采用结构设计软件ETABS和SATWE对结构进行了弹性整体计算、弹性时程分析和楼板应力分析,采用SAP2000软件进行了罕遇地震下弹塑性静力弹塑性分析,通过对计算结果的分析,表明结构设计是安全可靠的。
The height of the super high rise is 193m,and height to width ratio is 8.8,and whose structural form is frame structure of concrete filled steel tube columns with rectangular sections and R.C.Shear-wall structural system.There are four aspects beyond rules,including the super height,anomalistic torsion,discontinuous local floor slab,and irregular lateral rigidity.The software ETABS and SATWE were adopted in calculations and SAP2000 was adapted to structural push-over analysis.Based on the analysis and comparisons of calculation results,the safety of the structure was ensured.
