| Abstract | ||
| In this search, a new pattern is suggested to calculate the shear capacity of reinforced concrete (RC) exterior beam-column joints strengthened with fiber-reinforced polymer (FRP) under cyclic loads. A clear formula is developed that accounts for the shear capacity contributions from the transverse reinforcement, main reinforcing bars of the column or beam, and FRP sheet types. The coefficients of each commitment are calibrated utilizing 30 tests in the literature review and 6 experimental tests that had the information needed to derive a new equation. This search compared the inferred equation of Bousselham’s model and the modern equation with shear stress of the exterior beam-column joints and found that the values are close to reality when using the modern equation. The proposed method simplifies and ensures the reliability of calculating the necessary FRP sheet enhancements to prevent shear failure in exterior beam-column joints, making it highly useful for researchers and field engineers focused on structures strengthened with FRP sheets under seismic loads. | ||
