Prestressed Concrete Continuous Girder Bridge Reinforcement Simulation Analysis and Carrying Capacity Assessment

Abstract:

This article simulates prestressed concrete continuous girder bridge reinforced many times and evaluates carrying capacity after reinforcement. Taking the FuFeng bridge for an example, we analyze the bridge’s stress state in using by Midas software, evaluate the concrete ability of crack resistance, check the reinforced concrete structure ultimate carrying capacity, the cracking resistance and the stiffness, assess reinforcement effect and verify the accuracy and reliability of the simulation results. The maximum main compressive stress, maximum compressive stress, maximal main tensile stress and maximum tension stress of mid-span cross-section of the bridge are 1.6Mpa, 1.6Mpa, 0.3~0.5Mpa, and -1.2Mpa respectively, the mid-span center cross-section of deflection is 2.89cm. Reinforcement suppresses the development and expansion of the crack; the mid-span deflection tends to stabilize; the ultimate bearing capacity meets the Standard requirement basically; the emergency capacity is not enough; and the car whose weight over 55 tons is prohibited from passing.
