Analysis of the static ultimate strength of a bridge restrainer plate.

´˜^i‰pjF
A bridge restrainer plate resists seismic loads to prevent the fallout of girders from piers or abutments. The ultimate strength and mechanical properties of a plate are studied by suitable elasto]plastic analysis. Emphasis is marked on the shape and the frictional resistance acting between a pin and a plate. Numerical results show excellent coincidence with the experimental studies reported before. Parametric study reveals that shape and frictions exerts direct influence on the failure mode of a plate, and, in turn, the ultimate strength and ductility. These results help the establishment of the more rational design of a plate based on ultimate strength and ductility.
