Abstract

A dynamic analysis of both twisting and regular towers is carried out to determine the results of considering soil-structure interaction (SSI) on high-rise buildings. In addition, the difference between the seismic performance of using twisting towers over regular ones is investigated. The twisting tower is a simulation of the Evolution Tower (Moscow). The towers’ skeletons consist of RC elements and rest on a reinforced concrete piled-raft foundation. The soil model is considered as multi-layered with the same soil properties as the zone chosen for the analysis (New Mansoura City, Egypt). The only difference between both towers is their shape in elevation. The whole system is modelled and analyzed in a single step as one full 3D model, which is known as the direct approach in SSI. All analyses are carried out using finite-element software (Midas GTS NX). Dynamic output responses due to three records of seismic loads are proposed and presented in some graphs. Based on the results, it is concluded that SSI has a considerable effect on the dynamic response of tall buildings mainly because of the foundation flexibility, as it leads to lengthening the vibration period, increasing the story drift and the base shear for both cases.

考虑土-结构相互作用的 52 层扭转塔楼与规则塔楼抗震分析比较
对扭转塔楼和普通塔楼进行了动态分析,以确定考虑高层建筑土壤-结构相互作用(SSI)的结果。此外,还研究了扭转塔楼与普通塔楼在抗震性能上的差异。扭转塔是对 Evolution Tower(莫斯科)的模拟。塔的骨架由钢筋混凝土构件组成,并固定在钢筋混凝土桩筏基础上。土壤模型被视为多层土壤,其土壤性质与分析所选区域(埃及新曼苏尔市)相同。两座塔楼的唯一不同之处在于它们的立面形状。整个系统作为一个完整的三维模型进行建模和分析,这在 SSI 中被称为直接方法。所有分析均使用有限元软件(Midas GTS NX)进行。提出了三种地震载荷记录下的动态输出响应,并用一些图表表示出来。根据分析结果,可以得出结论:SSI 对高层建筑的动态响应有相当大的影响,这主要是由于地基的柔韧性,因为它导致振动周期延长,增加了两种情况下的楼层漂移和基底剪力。

期刊介绍: Earthquake Engineering and Engineering Vibration is an international journal sponsored by the Institute of Engineering Mechanics (IEM), China Earthquake Administration in cooperation with the Multidisciplinary Center for Earthquake Engineering Research (MCEER), and State University of New York at Buffalo. It promotes scientific exchange between Chinese and foreign scientists and engineers, to improve the theory and practice of earthquake hazards mitigation, preparedness, and recovery. The journal focuses on earthquake engineering in all aspects, including seismology, tsunamis, ground motion characteristics, soil and foundation dynamics, wave propagation, probabilistic and deterministic methods of dynamic analysis, behavior of structures, and methods for earthquake resistant design and retrofit of structures that are germane to practicing engineers. It includes seismic code requirements, as well as supplemental energy dissipation, base isolation, and structural control.
