摘要
本文对地震区复杂体型高层建筑采用楼板面内部分为弹性楼板、部分为刚性楼板的假定，将剪力墙简化为薄壁杆件，用三维杆系有限元法对结构进行地震反应分析。算例结果表明，高层建筑楼板开洞削弱后结构抗侧刚度有所降低，水平地震作用下剪力较大的楼板在底部几层范围内，随着层数的增加楼板剪力变化不显著。
In this paper,the seismic response analysis of high-rise buildings with complicated section is studied by three-dimensional calculation of the bar-system finite element method.The shear walls are simplified as spatial thin-wall columns and subject floors are assumed to be rigid.The results of calculated examples show that the lateral rigidity of high-rise buildings is reduced due to floor openings and seismic shear forces in lower floors are greater than those of high ones.Floor forces do not change much with the increment of storey numbers.
