Finite Element Simulation Analysis of A-shape Super-High Pier Beam Joints
In bridge structures, A-shape super-high pier with thin walls is a quite novel structure type which has a relatively complex force-transferring mechanism. To analyze its stress characteristics, the connecting parts of beams and pier column of a large-span bridge with A-type super-high thin wall pier are simulated by ANSYS. The stress distribution law of the connecting part is obtained. The results showed that on the beam joint of lateral bridge direction, the compressive stress of two forked hollow piers suffered from the central axis to outside of pier is increasing. The change of cross beam width and thickness exerts little impact on the maximum stress of the joints, while that of cross beam depth impact the stress much.These results can provide references to the design and construct of the similar structures.
