本文参考双曲拱桥和小跨度砧拱屋盖的计算方法,结合匈牙利学者L.Kollàr对圆弧形和V形等截面的内力分析,综合为一种实用的计算方法,引入犬、中跨度装配式钢筋混凝土多波双曲拱屋盖的设计计算。其适用范围及要点为,在双曲拱的长短边比2b/L<1/5时,近似地把拱波作为一为种圆弧形的截面,而主拱方向的内力按有拉杆的两铰圆弧拱进行分析,故称“两铰拱法”。
This article refers to the calculation method of double-curved arch bridge and small-span anvil arch roof, combined with H. H. Kollàr’s analysis of the internal forces of the arc-shaped and V-shaped sections, and integrates a practical calculation method to introduce the dog and midspan assembly. Design Calculation of Reinforced Concrete Multi - wave Double Curvature Arch Roof . The scope and main point of application is that, when the length and length of the double-curved arches is less than 2b/L<1/5, the arching wave is approximately an arc-shaped cross-section, and the internal force in the direction of the main arch is determined by two rods. The analysis of hinged arches is called “two-hinged arch method”.
