The Study of Mechanical Behaviors Performance of Bearing Form's Influence on Small-Radius Bridge
With the structural method, the "bending - twisting" coupling of the curve bridge is possible. As the small-radius bridge’s radius become smaller and smaller, the "Bending-Twisting" coupling become more and more common in order to discuss and verify the mechanical behaviors performance of supports' influence on small-radius bridge. This is done by changing the small-radius bridge’s supporting approach, using girder lattice method to construct a finite element model, analysis on a small-radius bridge of supporting longitudinal bending moment, torque and the influence of reaction force. The data shows that the double supports can reduce the small-radius bridge’s torque, make the medial and lateral support bearings equal reaction, make the small-radius bridge’s mechanical behaviors performance more reasonable, but was less affected by longitudinal bending moment. This conclusion of the small-radius bridge is significant to the designing work in the future.
