Abstract

Abstract

There were various cracks occurred during the construction of piers for a railway bridge.After comprehensive analysis,an effective method was accepted,with which structural adhesives were filled into the cracks firstly,then the cracks were sealed by high-strength reinforced concrete.In order to demonstrate the reliability of this reinforcement design,ANSYS FEM software was used to simulate and analyse the piers.The differences of stresses and linear stiffness and eccentricities of the piers were analyzed for un-cracked,cracked and strengthened conditions.The results show that the reinforcement design is safe and reliable.It can be used for reference of reinforcement design of similar piers with cracks.
