The present study focuses on enhancing the structural performance of RC beams through NSM technique, incorporating GFRP strips for comprehensive strengthening against flexural and shear. The methodology encompasses a series of planned steps. Initially, grooves will be incised into the concrete cover region, followed by a cleansing process. Subsequently, GFRP strips will be trimmed and cleaned to adhere to specified requirements. Epoxy material, prepared, will then be utilized to fill approximately 3/4th of the grooves. GFRP strips will be introduced into the grooves, and a subtle force will be applied to facilitate the flow of adhesive. After the removal of excess adhesive, the surface will be leveled, and beams will undergo a 7-days air curing process. The study places substantial emphasis on the precision of data collection and analysis. The calibration of instruments and gauges is prioritized, and the testing process will be exhaustively documented, accounting for any observed irregularities. The ensuing data will undergo scrutiny to assess the structural performance of the RC beams both pre and post NSM-GFRP strengthening. To gauge the effectiveness of the NSM-GFRP strengthening, thorough testing procedures will be executed using a UTM having a capacity of 100 tons. The experimental setup encompasses single and 2-point-loading tests designed to measure beam deflections at mid and quarter spans. For deflection measurements, dial gauges with a least count of 0.01 mm will be employed. Simultaneously, three strain reference points strategically located at the tension zone, compression zone, and near the neutral axis will be continuously monitored. “Demountable Mechanical Strain Gauges” with a least count of 0.002 mm will be employed for this purpose. Systematic recordings from both dial gauges and DEMEC gauges will be captured at 5kN load increments. The test procedure is versatile, applicable in both laboratory settings and on existing structures necessitating strengthening measures.
