摘要: 本文着重分析砼时间效应、几何非线性、材料非线性、施工期温差变化、湿度对徐变的影响、施工方案变化等因素对劲性骨架复合拱桥(万县长江大桥)恒载内力的影响,研究施工中的弹性稳定性变化.研究成桥状态极限承载力能力.

关键词: 非线性分析, 拱桥, 稳定, 承载力, 砼的时间效应, 材料非线性

Abstract: In this paper, the geometrical nonlubearities, temperature and humidity changes, time dependenl effects of concrete, material nonlincarities, method of construction and others to Long-span Stiffen Framework Reinforeed Concrete Composite Arcb Bridges have been analysed. The stability and load bearing capacity of Wanxian Yangtze River Bridge have been evalualed.

Key words: nonlinear analysis, arch bridge, stability, load-bearing capacity, time dependent effects of concrete material nonlinearities
