溧水紫金(永阳)科技创业园会展中心建筑总体外形呈复杂的空间球形曲面,采用轻型的大跨度空间单层网壳结构体系。设计过程中,分析了作用于结构的恒荷载、活荷载、风荷载、温度以及地震作用,并对各种工况进行组合,分析结构静力、动力特性,考察杆件承载力及结构稳定性。分析结果表明:经拓扑找形可实现杆件的最优化,高曲率空间双曲面为网壳结构提供了良好的整体稳定性;应用直接分析设计法对网壳进行稳定性分析时,考虑结构整体与构件初始几何缺陷,可准确地反映结构受力和稳定性情况。
Lishui Zijin (Yong Yang) Pioneering Park Convention and Exhibition Center, the overall shape of the building is a complex space spherical surface, the use of light long-span space single-layer reticulated shell structure system. In the process of design, the constant load, live load, wind load, temperature and earthquake acting on the structure are analyzed, and various working conditions are combined to analyze the static and dynamic characteristics of the structure. The bearing capacity and structural stability . The results show that the optimization of the bar can be achieved by the topology finding, and the hyperboloid of the high curvature space provides a good overall stability for the reticulated shell structure. When using the direct analysis and design method to analyze the stability of the reticulated shell, With the initial geometric defects of components, can accurately reflect the structure of the force and stability of the situation.
