摘要
厦门国际会展中心二期主展厅跨度81m,采用上弦为箱形梁的张弦梁体系;三期主展厅跨度99m,采用上弦三角拱形钢管桁架的张弦桁架体系。由于工程位于海边,屋面负风压大于屋面质量,抗风问题突出,针对张弦结构体系的屋面抗风设计、抗风结构的施工难题,阐述了台风地区大跨度张弦结构屋面的抗风设计与施工要点。
The roof structure system of the Xiamen Conference and Exhibition Center is a beam string structure,whose biggest span is 81m for phase I1 ,which applies box-shape beam top chord, and 99m for phase Ⅲ, which applies triangular steel tube arch top chord. Its prestressing construction is very difficult. Because the engineering is in the seaside area, wind resistant design is difficult, and concrete counterweight is used to prevent the great wind uplift. Meanwhile, the wind resistance design and key construction points are indicated in detail.
