摘要
双塔大跨度连体建筑结构形式及受力较为复杂,其结构安全性设计特别是抗震设计尤为重要。以某双塔大跨度连体建筑为例,基于MIDAS/Building结构分析设计系统及SATWE对整体结构进行小震反应谱分析,考虑施工模拟及P-delta影响,计算其水平及竖向地震作用,得到整体结构受力与位移参数,并进行设计验算。通过比较两种软件计算结果,可以看出该工程各项指标均符合规范要求,具有良好的抗震性能。基于计算结果,提出一些改进措施,为类似结构的计算与抗震性能分析提供参考。
The structure form and stress of twin towers long-span connected building is complicated. Its safety design is particularly important, especially for its seismic design. A twin towers long-span connected building is taken as an example in this paper. The design system is analyzed by MIDAS/Building and SATWE software by using small earthquake response spectrum,considering the construction simulation and the influence of P-delta, the horizontal and vertical seismic action is calculated and the structure stress and displacement parameters are proposed with design calculation checking carried out. Through comparing the calculating results by SATWE and MIDAS,the results show that the various parameters about the project are in conformity with standard requirements and the semismic property of the structure is in condition. Some suggestions are given based on the results and it can provide reference for similar projects.
