Analysis Study of Shear Strength Beam with UPR Patch using Finite Element Method

Abstract

Reinforced concrete beam is one of the structural elements of the building, which must be designed to meet the requirements set out in the building design regulations (Building Code of Practices). Handling the degradation of the shear span is very necessary to restore the shear strength of reinforced concrete beams and avoid the occurrence of shear failure which is very dangerous. This study aims to determine the effect of the flexural reinforcement ratio on the shear behavior of reinforced concrete beams filled with UPR-based patch repair mortar with numerical methods, and to determine the ratio of the flexural reinforcement ratio to the shear behavior of concrete beams by real testing and numerical testing. This research was conducted numerically with the help of ATENA Engineering 3d Software, to investigate the effect of UPR-mortar and reinforcement ratio on the shear behavior of reinforced concrete beams. The effect of UPR-mortar was investigated by comparing the results of numerical simulations between normal beams (N) and repair beams (R). Based on the data obtained from the analysis using the finite element method, it was found that the greater the flexural reinforcement ratio, the higher the collapse load given, and the shear capacity of the concrete beams patched using UPR-based patch repair increased compared to reinforced concrete beams in each each flexural reinforcement ratio.
