摘要
依托某超高层钢框架-核心筒结构体系,利用SATWE和ETABS软件进行了不同加强层布设方案的多遇地震作用下弹性整体计算分析,对比分析了不同水平加强层布设方案下结构的自振周期、位移以及内力,并采用ABAQUS软件对比分析了人工波、El Centro、TAFE三组波下的弹塑性时程分析结果。分析表明:水平加强层布置对此类超高层钢框架-核心筒结构的周期、位移、内力有不同程度的影响,需重点验算附近楼层内力和位移。
Taking a super-high steel frame tube structure as an example,different layout schemes of reinforced layers were studied by using SATWE and ETABS earthquake softwares to conduct the elastic calculation analysis under frequent,natural vibration period of the structure with different horizontal reinforced layer layout scheme were compared and analyzed. ABAQUS software was used to compare the elastic time-history of the three waves of artificial wave,El Centro and TAFE. The results showed that the arrangement of horizontal stiffened layers affects the period,displacement and internal force of such super high-rise steel frame-core tube structure,and the internal force and displacement of the floor need be check.
