STRUCTURAL EVALUATION OF EXISTING RC BUILDING AND RETROFITTING

Abstract

Structural evaluation of existing structures is important in current times. The main aim of the structural evaluation is to determine whether the existing structure has sufficient capacity to bear the current state of loadings. The main objective of this report is to evaluate the existing RC building. The tools used to evaluate the structural capacity is NDT testing and analysis of the structure in ETABS. The NDT tests performed are mainly Core cutting of concrete elements, Ultrasonic Pulse velocity test, Rebound hammer test, and half-cell potential test. The structural analysis has been carried out in ETABS mainly focusing on finding out the design reinforcement mainly for earthquake loading. The evaluation of the G+8 building situated in Mohali has been carried out. Retrofitting methods suggested consists of RC strengthening and FRP wrapping. The capacity enhancement and its cost effectiveness were compared.
