dc.description.abstractCalibration of the flexural resistance factors in the American Association of State Highway and Transportation Official’s (AASHTO) Load and Resistance Factor Design (LRFD) format is performed for bridge girders prestressed with Carbon Fiber-Reinforced Polymers (CFRP). The underlying principle of the LRFD design is to achieve a uniform probability of failure (target reliability) for all possible design scenarios, which is achieved through resistance and load factors. Calibration of the resistance factors requires an extensive design space to be applicable to different design scenarios. For this purpose, 12 design cases with various span lengths, girder positions, girder spacing, roadway widths, and failure modes were considered. The load and resistance model random variables and their statistics, flexural resistance model accuracy, and the results of Monte Carlo simulation through which resistance factors were derived for different target reliabilities for interior and exterior girders failing in tension and interior girders failing in compression are presented.
