本文介绍的结构方案是:Γ型柱抛物线三铰拱空间桁架组合大跨结构,按固体力学力学分析的方法,导出了杆件的内力计算公式。经计算可以看出该结构形式的用钢指标与同荷载、同跨度的网架结构、梁式空间桁架等七种大跨结构相比,其用钢量最省。而且具有空间利用率高、受力性能好等优点,结构造型也显得壮观气魄。是一种较好的钢结构与钢筋混凝土柱的组合形式。
The structure scheme introduced in this paper is: the parabolic three-hinge arch space truss combination long-span structure, according to the solid mechanics analysis method, derived the internal force calculation formula of the rod. It can be seen from the calculation that the amount of steel used in this structural form is the lowest in comparison with the seven large-span structures such as the same load, the same-span grid structure, and the beam-type space truss. Moreover, it has the advantages of high space utilization, good mechanical performance, and so on, and the structural shape is also spectacular. It is a better combination of steel structure and reinforced concrete columns.
