【Abstract】 Combined with an engineering example, the focus is on the study of the force change law of the spherical hinge using the horizontal rotation construction method under different eccentric distances. In this paper, the finite element software MIDAS FEA is used to establish a local model of the rotating system, and the force distribution of the spherical hinge under different eccentricity is obtained. Thus,the calculation results can guide the construction of this project and provide experience for the construction of the same type of bridge.更多还原
