摘要
Abstract
In this paper, the load sharing ratio of the continuous-beam-arch combined bridge is defined by the mid-span deflection of the continuous-beam-arch combined and continuous beam which have same span and section. The formula of load sharing ratio based on deflection is deduced by mechanical method beam-to-arch in mid-span uniform load. The accuracy of the formula is verified by changing the structural parameters, and the in-fluence factors of the load sharing ratio of the continuous-beam-arch are analyzed. The load sharing ratio of the composite bridge based on the deflection can be calculated by using the mid-span deflection of the actual bridge. It can measure the working mechanism of the real bridge, which has certain reference value for grasping the load sharing ratio of the bridge.关键词
