| Abstract: | Based on the widening construction of the Fengshan grade separation bridge in the line of Xiamen-Zhangzhou expressway,the experimental study was conducted to analyse and compare the static characteristics of key section such as stress distribution,deflection and lateral load distributions in the process of using different longitudinal connections to widen the skew prestressed continuous bridge with hollow slab.The mechanical properties of different longitudinal connections in the action of the supporting un... |
