地震作用下双塔连体结构体系的变形和内力分布较为复杂,针对某一大底盘对称双塔连体结构,应用大型通用有限元软件建立结构的整体非线性分析模型,对该结构进行动力特性分析。同时对结构进行只输入水平向地震动、只输入竖向地震动和输入水平竖向耦合地震动三种不同工况的非线性时程分析,通过对比分析三种工况下的动力响应,研究相同烈度、相同水准的不同地震动对结构响应的影响。分析表明,其他条件相同时,在不同地震波作用下,对连体结构竖向位移起主要控制作用的因素不同。通过对计算结果的分析,可以比较全面地掌握连体结构的抗震性能,为连体结构进一步的研究和设计提供一定的理论参考依据。
Under the action of earthquake, the deformation and internal force distribution of the double-column structure are complex. For a large-scale symmetrical twin-tower structure, a large general finite element software is used to establish the overall nonlinear analysis model of the structure. The dynamic characteristics analysis. At the same time, the nonlinear time history analysis of three different working conditions of the structure, which is inputting only horizontal ground motion and inputting only vertical ground motion and input horizontal vertical coupling ground motion, is carried out. By comparing and analyzing the dynamic response under the three conditions, The same intensity, the same level of different ground motion on the structure of the response. The analysis shows that under the same conditions, the factors controlling the vertical displacement of the Siamese structure under different seismic waves are different. Through the analysis of the calculation results, the seismic performance of the Siamese structure can be fully grasped, which provides some theoretical reference for the further research and design of the Siamese structure.
