摘要

摘要:本文分析了某单线铁路桥梁的一些设计参数对其整体稳定性的影响。在本分析中考虑了以下结构参数:封闭式桥梁，上部由水平构件组成，构件之间没有连接(对角线);封闭式桥架，上绕组由水平构件构成，扎带呈交叉对角线形式;静力方案的拱在横向——铰接、固定或门式框架。所进行的分析是基于标准SR EN 1993-2:2007。欧洲规范3:钢结构设计。第2部分:钢桥(EC3-2)。所得结果可为桥梁或其他类型金属结构的拱结构设计提供参考。

Influence of Design Parameters on General Stability of Tied Arches with an Upper Bracing

Abstract The paper shows the influence of some design parameters on the general stability of a single-track railway bridge, having the structure made of circular steel arches with rigid vertical hangers. The following structural parameters were considered in this analysis: closed bridge with an upper winding made of horizontal members without links (diagonals) between them; closed bridge, with upper winding made of horizontal elements and ties made in the form of cross diagonals; static scheme of the arch in the transverse direction – hinged, fixed or portal frame. The analysis carried out is based on the normative SR EN 1993-2:2007. Eurocode 3: Design of steel structures. Part 2: Steel Bridges (EC3-2). The results obtained can be useful in the design of the arches structures for the field of bridges or other types of metal structures.
