Title:

Finite Element Analysis and Experimental Comparison for Repair of Corrosion Damaged Steel Girder Ends Using Ultra-High Performance Concrete Encasement

Abstract:

Corrosion of steel bridge girder ends due to leaking expansion joints is a widespread problem in the US. This type of corrosion damage impairs the bearing capacities of girders. Current repair methods are time-consuming, expensive, and may require closure of the bridge during repair. Experimental and analytical studies have been conducted at the University of Connecticut to develop a novel repair method using ultra-high performance concrete (UHPC) encasement for corroded girder ends. Three large scale experiments demonstrated the effectiveness of the repair in recovering the original capacity of the damaged girders. The experimental results were then used to validate a refined finite element (FE) model for the repair. The calibrated FE models were used to predict performance of various repair designs and can be used to develop a general repair design method that facilitates the implementation of this promising repair method. This paper will discuss the construction of the FE models and comparison of the FE results to the experimental tests. The findings from the study of different repair geometries are presented.
