Reinforced concrete beam cracks are a frequent structural problem that, if left unchecked, could endanger the overall safety. Although reinforced concrete buildings are widely used, however they are vulnerable to cracking of things such thermal expansion, shrinkage, and excessive loading. Even while conventional temporary support techniques like hydraulic jacks and fiber reinforced polymer (FRP) work well, they might be expensive, time consuming, or not ideal in an emergency. With a focus on the appropriate plate thickness and yield strength for efficient stabilization, this study explores the possibility of using steel plates as a temporary reinforcing technique for fractured concrete beam. Reinforced concrete beams supported by high strength steel plates with thickness varying from 5 mm to 10 mm and yield strength between 400 MPa and 700 MPa are analyzed as part of the study. The steel plates are firmly fastened to the beam using bolts, over the course of 14 days to 30 days. As the results, showed that thicker plates dramatically decreased beam deflection, eliminated slip displacement, and optimized crack width stability. These results imply that, thicker plates provide better temporary support under high load conditions. As well as, steel plate may be a suitable and affordable option for emergency or temporary cases, for the stabilization when immediate repair may not be possible.
