The closure of Multi-span continuous rigid frame bridge is one of important steps in its construction. The selection of closure scheme determines the deformation and stress state of the bridge when construction is completed. In this paper, based on the situation of Jing River Bridge, which is now under construction in Gansu Province, finite element method is applied to analyze and compare the inner...
Wind is strong at the site of Jing River Bridge, the effect of wind load and other possible loadings on the stability of the structure is considered. Based on the actual construction stage, this paper mainly analyzed the nonlinear stability of No.6 and No.7 piers of the Jing River Bridge. Material nonlinearity and geometric nonlinearity are both included in the numerical investigation. The results...
