Structural stress analysis of pier and abutment of Bailey steel Bridge

The pier and abutment of Bailey steel bridge are fixed at the lower end of the vertical cantilever rod to bear the main load: bailey steel bridge span dead load, the weight of the train, centrifugal force, braking force and the effect of the wind on the bridge and the train.

The dead weight of pier and abutment N2, the horizontal loads such as wind force, water pressure, raft or ship collision force acting directly on the side of pier, and earth pressure acting on abutment P2. So on the pier, abutment as a whole, it belongs to the eccentric compression structure.
