ABSTRACT
Bridges are infrastructure buildings that are commonly used and very functional in everyday. One of the structural components of the bridge is a reinforced concrete beam as a load bearer that will be forwarded to the foundation. The shear capacity of reinforced concrete beam structures sometimes cannot meet the existing requirements. This can be caused by increased loads, inadequate shear strength in the initial design and material damage due to natural factors. There are several methods that have been carried out to overcome the decrease in shear strength in beam structures, namely reinforcement methods by externally bonded (EB) and near-surface mounted (NSM). In reality, shear reinforcement with EB and NSM methods in implementation only relies on epoxy adhesion and concrete blankets, which still causes structural failure. The deep embedment strengthening method (DE) can be proposed as a shear reinforcement for reinforced concrete beams to overcome the previous problems. Reinforcement with DE method is a shear reinforcement that is reinforced in the core of reinforced concrete beams. This research was conducted by embedding 8 reinforcements vertically with a distance of 200 mm along the shear span. In this study, the behavior of reinforced concrete beams resulting from experimental testing was compared with the behavior of reinforced concrete beams resulting from finite element modeling using ABAQUS. The results of experimental testing on beams reinforced with the DE method showed that the maximum load was 30.30 kN and the maximum deflection was 18.00 mm. While experimental testing on the control specimen the maximum load result is 27.00 kN and the maximum deflection is 13.24 mm, the beam reinforced with the DE method has a greater maximum load and deflection result with a difference of 12.22% and 35.95% against the control beam. In the finite element modeling with DE method, the maximum load is 30.646 kN and the maximum deflection is 13.00 mm. While finite element modeling on the control specimen the maximum load result is 27.042 kN and the maximum deflection is 9.55 mm, then the beam modeling reinforced with DE method has a greater maximum load and deflection results with a difference of 13.33% and 36.13% against the control beam modeling. The failure model that occurred from experimental testing and finite element modeling on the specimen with DE reinforcement experienced flexural failure, while the control specimen experienced shear failure.
