通过运用结构的复合非线性 (几何非线性和材料非线性 )极限分析理论 ,对国内一座在建的 36 8m大跨径钢管混凝土中承式系杆拱桥进行了复合非线性稳定性空间分析 ,在此基础上 ,还对该钢管混凝土拱桥主拱肋矢跨比、钢管壁厚及混凝土标号等的设计合理性进行了一些探讨
A composite nonlinear stability analysis of a 368m long span CFST arch bridge under construction in China is carried out by using the theory of composite nonlinear (geometric nonlinearity and material nonlinearity) limit analysis. On this basis, some discussion is also made on the design rationality of the main arch rib-span ratio, the pipe wall thickness and the concrete grade of the CFST arch bridge
