| 摘 要： | 对于钢管混凝土桁式拱桥，当宽跨比较小时桥梁拱肋的横向稳定性是桥梁安全性的关键，因而需要用弹塑性理论重新计算结构的稳定安全系数。分析在不同风荷载作用下的材料非线性及几何非线性的稳定性，得出不同的结果。

| Abstract: | Regarding steel pipe concretes clothes rack type arched bridge,when wide cross is quite small,this bridge arch rib's transversal stability is the bridge secure key,thus needs to use the elastoplasticity theory recomputation structure the stable safety factor. The analysis under the different wind load function's material misalignment and the geometry misalignment stability,obtains the different result finally. |
