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
properties of (RC) beams to maintain the required service life and load capacity of
any (RC) structure is considered as an interesting area of study. In this paper, a
Finite Element (FE) investigation is conducted on a (RC) beam which was
previously strengthened experimentally with Self-compacting concrete (SCC)
jacketing reinforced with galvanized welded steel wire mesh (SWM). A (FE)
model using the commercial program ABAQUS was created to predict the loaddeflection
behavior and crack/failure pattern of the strengthened beams. Based on
both experimental and numerical model achieved results, all jacketed samples
showed ductile mode of failure and flexural cracks pattern. The FE model results
were in good agreement with the experimental results. It was found that adding an
external steel plate will increase the ultimate capacity and stiffness of the jacketed
samples, but it will change the mode of failure to brittle shear cracks, the
strengthened jacketed samples with an external steel plates restored on average
172 % of the original control beams load capacity.
