摘要

摘要:本文介绍了无上支撑、带有刚性垂直吊杆的圆拱、敞开式或独立式桥梁上部结构一般稳定性验算的有关问题。根据SR EN 1993-2:2007标准，对一座跨度为30 m的单线铁路桥梁进行了数值工作分析。欧洲规范3:钢结构设计。第2部分:钢桥(EC3-2)。所进行的工作分析有助于加深对规范中所提出的程序的了解，以及在桥梁或其他类型金属结构领域的拱上结构的设计。

Aspects Regarding EC3-2 Procedure for Stability Verification of the Free-Standing Circular Arches

Abstract The paper presents aspects related to the verification of the general stability of the bridge superstructures on circular arches with rigid vertical hangers, bridges of open-type or free-standing, without upper bracing. A numerical worked analysis is carried out for a single-track railway bridge with a span of 30 m, which is based on the normative SR EN 1993-2:2007. Eurocode 3: Design of steel structures. Part 2: Steel Bridges (EC3-2). The worked analysis carried out can be useful in deepening the knowledge of the procedure presented in the normative, as well as in the designing of the structures on arches in the field of bridges or other types of metal structures.
