摘要
交错混凝土桁架剪力墙结构是一种新型的建筑结构形式,该结构用与四周布置的剪力墙或两侧外立柱相连的混凝土桁架代替横墙,其桁架沿高度方向隔层错跨布置.与传统剪力墙相比,该结构具有2倍开间的无内柱空间、节省材料、减轻自重和能在桁架弦杆以外部分随意开洞等优点,但其结构抗震问题有待研究.利用SAP2000有限元软件对某18层交错混凝土桁架剪力墙结构进行了Pushover分析.结果表明,在El-centro波作用下,该建筑的最大层间位移为1/366,该值远小于《建筑抗震设计规范》限值1/120,并在地震中有良好的表现.
The staggered concrete truss shear wall structure is a new form of structure.This structure replaces the cross wall with the concrete truss which is connected to shear walls distributed around or connected to external columns on both sides,and the truss arranges in staggered span every alternate storey in vertical.Compared with traditional shear wall,it has advantages such as double spacing non-internal column space,material saving,weight reduction and at will hole opening in area out of truss chord,etc.But issues of its structural anti-seismic remains to study.Pushover analysis on the staggered concrete truss shear wall structure of the 18 floors building was made by the SAP2000 finite element software.Results show that the maximum inter-storey displacement of this building under the action of El-centro wave is 1/366 which is much less than the limiting value 1/120 in the “Code for seismic design of buildings” and this building has good performance in an earthquake.
