摘要
厦门会展中心三期展厅跨度99米和72米,采用上弦压杆为倒三角拱形钢管桁架的张弦梁体系,局部27米楼盖采用双向桁架组合楼盖,取得技术安全、质量可靠、工期紧凑、造价经济、结构美观的良好效果。通过对屋盖、楼盖体系的选型、设计、施工难点分析,对比二期类似结构,进行了张弦梁屋盖及楼盖结构的受力性能及应用实践的优化,可供类似工程参考借鉴。
The roof structure system of the Conference and Exhibition Center Phase III is a beam string structure, its pre - stressing is very difficult. A minute description of the pre - stressing construction plan is given. Concrete counterweight was used to prevent the great wind uplift. Two - way truss and combination floor system with TMD systems were used to reduce the floor vibration for the local 27m span across floor. It can be a reference for structural design and construction of similar projects.
