Reliability-based design optimization of concrete flexural members reinforced with ductile FRP bars
Highlights A RBDO procedure is developed and applied to DHFRP-reinforced flexural members. Strength, ductility, stiffness, and reliability constraits are considered. Bars are optimized for cost minimization for a bridge deck and building beam. Small differences in optimial configuration were found for the different applications.
Abstract In recent years, ductile hybrid FRP (DHFRP) bars have been developed for use as tensile reinforcement. However, initial material costs remain high, and it is difficult to simultaneously meet strength, stiffness, ductility, and reliability demands. In this study, a reliability-based design optimization (RBDO) is conducted to determine minimum cost DHFRP bar configurations while enforcing essential constraints. Applications for bridge decks and building beams are considered, with 2, 3, and 4-material bars. It was found that optimal bar configuration has little variation for the different applications, and that overall optimized bar cost decreased as the number of bar materials increased.
