摘要
提出了一种适用于大跨度干煤棚工程的结构形式——索托网架.通过与斜拉网架结构的对比分析,研究了索的位形对索力、网架特征部位杆件内力、杆件与索内力的比值以及挠度的影响,得出了索的合理位形.结果表明:索托网架结构可以更加充分发挥索应力高的特性,具有结构合理、用钢量低、净空高等优点,符合大跨度干煤棚的要求.
This paper presented a new structural style, i.e. cable-supported spatial grid, which was applied in large span dry coal sheds. The influence of the configuration of cable on the force of cable and beam, the ratio of beam force to cable force and the deflection of span was investigated, and a rational configuration of cable was obtained. The results show that the cable-supported spatial grid can maximize the use of material strength, and have the advantages of low usage of steel, large span and sufficient headroom.
