简介
This paper develops reliability-based design provisions for eccentrically loaded rectangular concrete short columns reinforced with fiber-reinforced polymer (FRP) bars. First, closed-form solutions for the axial force-moment strength interaction diagram were presented. Subsequently, the statistical parameters of the resistance model were estimated based on available experimental data and Monte Carlo simulations. The first-order second-moment (FOSM) method was then applied to calibrate strength reduction factors to meet the uniform target reliability level βT= 4.0. To verify the results obtained, a comparison between reliability indexes obtained from Monte Carlo simulations and those from the FOSM was conducted. Finally, sensitivity analyses were performed to evaluate the influence of various design parameters on the reliability index, indicating that the reliability of FRP-reinforced concrete columns is …
