对一栋超高层建筑采用三种不同结构体系进行比较,最终确定采用钢框架-支撑结构体系,其中层1～4为型钢混凝土结构。采用SATWE,ETABS程序对结构进行多遇地震作用下的计算,各项计算指标均满足规范要求。并对整体结构进行了弹性动力时程分析补充计算和罕遇地震作用下静力弹塑性分析。计算结果表明,该结构体系是安全可行的。
For a super high-rise building using three different structural systems for comparison, and ultimately determine the use of steel frame - the support structure system, in which layers 1 to 4 steel reinforced concrete structure. The SATWE and ETABS programs are used to calculate the structure under the action of frequent earthquakes. The calculated indexes meet the requirements of the code. And the whole structure is subjected to the elastic dynamic time-history analysis and the static elastic-plastic analysis under the rare earthquakes. The calculation results show that the structural system is safe and feasible.
