STRUCTURAL EVALUATION OF AN EXISTING RC BRIDGE DECK ON MDR-09 NEAR SRIRANGAPATTANA USING NDT AND FEM

Abstract: Bridges are the major part of infrastructure allowing the flow of human beings, goods and vehicles. SHM has been widely applied in various engineering sectors due to its ability to respond to adverse structural changes, improving structural reliability and life cycle management. Structural health monitoring (SHM) is a process that aims at detecting, locating, and quantifying damage in structures at an early stage in order to avoid unexpected failure. Structural health monitoring aims to provide quantitative and reliable data on the real conditions of a bridge, observe its evolution and detect the appearance of degradations. Non-destructive testing (NDT) is a testing and analysis technique used by industry to evaluate the properties of a material, component, structure or system. It is often necessary to test concrete structures after the concrete has hardened to determine whether the structure is suitable for its designed use. The purpose of this study is to review Structural Evaluation of an existing bridge by carrying out non-destructive test named rebound hammer along the bridge by concerned authority to obtain the reduced compressive strength parameter of superstructure of bridge and modelling and analyzing it by FEM software specifically STAAD Pro and comparing the results such as bending moments, forces, and deflections and stresses and providing required repair and rehabilitation techniques.
