本文研时光究钢管砼拱桥任意形状拱肋截面的钢管和砼内力分配问题,利用有限元法得出截面内力,在此基础上推出了钢管和砼的内力分配和应力表达式,可供设计钢管砼拱桥的人员参考。
In this paper, we studied the problem of internal force distribution of steel pipe and concrete with arbitrarily-shaped arch rib cross section of steel tube concrete arch bridge in time. The internal force of section was obtained by finite element method. Based on this, the internal force distribution and stress expression of steel tube and concrete were introduced. Concrete arch bridge staff reference.
