项目位于高烈度地区,存在扭转不规则、偏心布置、楼板不连续、尺寸突变和局部不规则.针对上述不规则项采取了专项分析,同时制定了合理的结构性能化目标,进行计算分析验证结构性能.裙房存在 26m×41m的大跨空间,采取了钢拱结构形式,并通过参数化技术优化钢拱的几何形状,改善了结构受力,对于钢拱结构进行了弹塑性、舒适度、竖向地震、节点、稳定性施工模拟专项分析.同时比较了钢拱在增加拉索的方案中,可减少水平地震力引起的拱结构内力,但反应谱法无法考虑拉索受压索力退出工作的情况,其计算方法需进一步的研究,但类似工程可考虑时程分析计算结果后调整相关杆件的内力设计方法.
The project is located in high intensity area,there are torsion irregularity,eccentric layout,floor discontinuity,size mutation and local irregularity.In view of the above irregular items,a special analysis was carried out,at the same time,a reasonable structural performance target was formulated,and the structural performance was verified by calculation and analysis.There is a large span space of 26m×41m in the podium,and the structure with steel arch was adopted.The geometric shape of the steel arch was optimized through parametric technology to improve the structural stress.Special analysis was conducted on the elastic-plastic,comfort,vertical earthquake,node,and stability construction simulation of steel arch structure.At the same time,the internal force caused by the horizontal seismic force of the arch structure in the high intensity area was compared in the scheme of increasing the cable.However,the response spectrum method can not consider the situation that cables are forced out of service,and its calculation method needs further study.Similar engineering can also consider the internal force of the relevant bar after time history analysis of multi wave calculation results.
