摘要
东莞国贸中心裙房采用框架结构体系,为满足建筑在不同位置的功能需求和考虑结构的合理性,采用12m×12m大柱网可实现建筑与结构的高度结合。裙房大跨度钢屋盖为不规则空间曲面网格,由单层网壳及竖向支撑系统构成,重点介绍三维参数化建模运用的基本思路以及优势,并给出屋盖设计计算结果。裙房间连桥为跨度38m的斜拉拱桥,对其结构位移、自振频率、人行舒适度等进行计算分析,进一步优化斜拉拱桥体系的设计以节省材料用量。
The podium of Dongguan International Trade Center adopts frame structural system with the column grid of 12m x12m in order to meet the functional requirements in different locations of the building and to consider the rationality of thestructure in the meantime, realizing the perfect coordination between architecture and structure. The complex spatial steelroof of podium is irregular spatial curved grid, composed of single-layer latticed shell and vertical support system. The basicconcept and advantages of employing three dimensional parametric modeling were illustrated, and the calculation results ofthe roof were provided. A 38m-span diagonal-span arch bridge, which was a connected passage of the two parts of podium,was analyzed in detail, including deformation, natural frequency, pedestrian comfort, and the bridge system was optimizedto save the materials.
