摘要
淮州新城国际会展中心为体型复杂的结构,平面底座呈圆形,采用钢框架-中心支撑结构。大跨及悬挑屋面采用空间扭曲交叉网格、单层网壳结构。基于结构体系网格构成及地基基础设计,重点从建筑、结构、幕墙参数一体化,解决竖向刚度突变,大跨度悬挑舒适度,抗连续倒塌分析进行了介绍。对结构进行了整体静力、整体稳定、抗震性能化、BRB专项设计等分析,并针对超限类型采取相应抗震措施。结果表明,整体结构安全可靠。
Huaizhou New City International Exhibition Center is a particularly complex structure,a steel frame-central support structure with a circular plane base is adopted.The large-span and cantilevered roof adopt spatially twisted cross grid and single-layer reticulated shell structure.Based on the grid composition of the structural system and the foundation design,the introduction focuses on the integration of building,structure and curtain wall parameters,resolution of sudden changes in vertical stiffness,comfort of large-span cantilever,and collapse resistance analysis.The overall static,overall stability,seismic performance and BRB special design of the structure were analyzed and the corresponding seismic measures were taken for out-of-limit types.The results show that the whole structure is safe and reliable.
