Strengthening of Reinforced Concrete RC Beams using SWM SCC jacketing

Abstract

Strengthening of reinforced concrete (RC) beams with Self-compacting concrete (SCC) jacketing reinforced with galvanized welded steel wire mesh (SWM) has been an important area of study so far. Increasing the mechanical characteristics of (RC) beams and structures to maintain the required service life and load capacity of any (RC) structure, is considered as an interesting area of study. In this research, a Finite Element (FE) investigation is conducted on series of (RC) beams which were previously strengthened experimentally with Self-compacting concrete (SCC) jacketing reinforced with galvanized welded steel wire mesh (SWM). A (FE) model will be conducted to predict the load-deflection behaviour and crack/failure pattern of the strengthened beams. Based on both experimental and numerical model achieved results, the FE model results will give some important conclusions and recommendations regarding the experimental strengthening of RC beams using this technique. Another strengthening technique using an external steel plate will be also used and checked to be compared with the SCC SWM strengthening technique. Finally parametric study will be conducted.
