【摘要】 指出了近年来大跨度桥梁的结构分析广泛地采用有限单元法,通过建立有限元模型,对钢管混凝土拱桥在施工及营运阶段非线性应力进行了分析,从而得到更接近真实状态的应力结果。更多还原

【Abstract】 Point out in recent years,finite element method has been widely used in structure analysis of long span bridges.By finite element models,the authors analyzed nonlinear stress of concrete-filled steel tubular arch bridge in building and operating.People can acquire stress datum that tend to real situation.更多还原
