摘要
浙江淳安南浦大桥结构非线性分析结果表明,对大跨径(大于300m)、宽跨比较小(接近1/20)的钢管混凝土桁式拱桥,几何非线性和材料非线性对拱肋的影响均较大,在设计和施工时不应忽略。
The result of nonlinear analysis of the Zhejiang Chun'an Nanpu Bridge shows that for steel tube reinforced concrete trussed arch bridge with large span and small width-span-ratio, both geometric non-linearity and material non-linearity would produce impacts on arch ribs, and it should not be ignored in design and construction.
