双塔连体结构是在两塔楼上部设置连体而形成的一种复杂的高层建筑结构形式,在我国实际工程中的应用越来越多,但目前对此类结构的抗震性能研究还不够全面和深入。针对一双塔连体高层建筑,进行了模拟地震振动台模型试验,并利用大型通用有限元分析软件ANSYS进行了结构动力特性和动力反应分析。结果表明,连体刚性连接节点及墙体采取的内设型钢的加强措施可以满足结构抗震要求;连体结构的连体部分对竖向振动效应的放大十分明显;应进一步加强连体桁架构件的整体和局部稳定性;开有较大洞口的楼层应采取改善延性的措施。
The twin tower structure is a kind of complicated high-rise building structure which is formed in the upper part of the two towers. It is applied more and more in our country’s actual project, but the research on the seismic performance of this kind of structure is not comprehensive enough And in-depth. A pair of high-rise buildings with one tower and two towers were simulated by a shaking table test, and the structural dynamic characteristics and dynamic response analysis were carried out by using the large-scale general finite element analysis software ANSYS. The results show that the strengthening measures of integral section steel adopted by the rigid connecting nodes and the inner wall of the wall can meet the seismic requirements of the structure. The integral part of the one-piece structure amplifies the vertical vibration effect obviously. The joint truss component Overall and local stability; open a large hole in the floor should take measures to improve ductility.
