Numerical Analysis on Surplus Bearing Capacity of Chipped Bridge Piers

Abstract:

Bridge piers generate local destruction at impact point after suffering medium and low speed impact, and then their bearing capacities decrease a lot. Based on the formula in code, this paper used ANSYS to analyze surplus normal section load-carrying capacity of reinforced concrete bridge piers with notches in different sizes. The relation curve between axial bearing capacity of piers and scaling area of concrete was obtained. After comparing with formula in code, a new formula was obtained, which can be used in calculating surplus normal section load-carrying capacity of chipped bridge piers. In addition, damaging process of chipped bridge piers under axial pressure was simulated accurately by ANSYS.
