武汉市民之家属大跨连体复杂高层结构。介绍本工程主要采取的构造措施和计算手段,包括塔楼筒体的抗倾覆验算、连体桁架与筒体的连接节点设计、连体层楼板的设计。分析了扭转位移比指标的特点,由于连体层上下结构层长宽比的变化,导致扭转位移比的突变,这种不规则性属于连体结构的固有特点,通过对塔楼部分的加强能保证结构整体在大震作用下的安全性。通过公式推导,得出结构整体抗倾覆系数与基底零应力区之间的联系。
Wuhan people’s family of large-span Siamese complex high-rise structure. The main construction measures and calculation methods adopted in this project are introduced, including anti-overturning checking of tower shell, connecting node design of integral truss and cylinder, and design of connecting floor. The characteristics of the torsional displacement ratio index are analyzed. As the aspect ratio of the upper and lower structural layers changes, a sudden change in the torsional displacement ratio is caused. This irregularity belongs to the inherent characteristic of the conjoined structure. By strengthening the tower part, Structure as a whole in the earthquake under the action of security. Through the formula derivation, the relationship between the whole structure anti-overturning coefficient and the base zero-stress zone is obtained.
