Tensing hangers to raise the main girder to leave the brackets is a complicated nonlinear process in construction of self-anchored suspension bridge.Considering bearing capacity of the structure and tensing facilities,the method of determination of state of girder leaving brackets,the optimal scheme of reduction of times of tensing and number of stretching bars are studied.Using this method in construction of Wanxin bridge,the ideal state of main girder leaving brackets can be achieved after four times of t...
