摘要
本项目主楼平面尺寸为99m x 79m,高度为60m,由四个刚度不同的塔楼组成的回字形结构。针对工程的特点、超限情况,基于性能化结构抗震设计,在多遇地震作用下采用阵型分解反应谱法和弹性时程分析方法进行结构整体计算分析、稳定分析,对以上分析结果中的薄弱部位及关键部位采用相应构造措施,以保证抗震性能目标的实现。结果表明该结构体系是安全、可行的。
The main building of this project is 99 m x 79 m with a height of 60 m. The structure is composed of towers of 4 different rigidity. This paper investigates the system characteristics and the seismic performances of the structure. Under the actions of multiple earthquakes,the decomposition reaction analysis and elastic time history,analysis are used to carry out calculation and stability analys is of the whole structure. Some constructional measures were employed to enhance the seismic performances of weak components so as to ensure the seismic safety of the building. The results indicate that this structure system is safe and feasible.
