预应力混凝土刚架索梁结构在某工程中的应用

Research on the application of prestressed concrete truss cable-beam structure in a building

对黑龙江省博物馆工程的大跨度楼盖进行了方案对比,综合比较了钢结构网架、普通预应力混凝土梁和预应力混凝土刚架索梁3种结构形式的受力性能、经济性以及对建筑使用功能的影响。结果表明,预应力混凝土刚架索梁在钢筋混凝土结构大跨度楼盖中应用时具有更好的综合效益。

Schemes of the large span floor in Heilongjiang Museum were compared.The three kinds of structures include steel grid structure,common prestressed concrete beam and prestressed concrete truss cable-beam.The structural performance,economic benefit and the effect on the architectural function of the three kinds of structures were compared in detail.The comparison results indicate that using prestressed concrete truss cable-beam in RC large span floors will get the best synthetical effect.
