产业园大柱网梁板结构经济性分析

Economical analysis of the beam and slab structure of industrial park with large column grid

针对产业园8.4 m×8.4 m的大柱网,对五种不同楼面活载的工况分别设计了四种梁板结构布置方案,并采用PKPM技术分析了各种方案下的总钢筋用量、混凝土用量、总造价。研究表明,双次梁等跨度结构布置经济性最好,可在工程中广泛应用。

For industrial park with the large column grid of 8.4 m×8.4 m, four kinds of beam and slab structures are made for five different working conditions each, and the total usages of steel and concrete, and the total construction cost are calculated based on the analysis of PKPM. The research shows that, the economical efficiency of the kind of the structural arrangement of double-beam with equal span is the best among the four kinds, that could be widely used in projects.
