Abstract:A seismic retrofit strategy using precast infill panels made of a ductile high-performance fiber-reinforced concrete (HPFRC) is investigated for use in critical-use, steel moment-frame buildings. The infill panel material is a self-consolidating concrete mixture that uses high-strength steel fibers. In the retrofit, the panels infill existing steel moment-frame bays, adding stiffness, strength, and energy dissipation capacity and use pretensioned, slip-critical bolted connections. Component-level single-panel tests with various reinforcement layouts and geometry are conducted and show promising cyclic behavior in terms of hysteretic stability, ductility, energy dissipation, and damage tolerance. A connection detail using threaded studs is verified for performance and repeated use. Recommendations for future phases of research, including large-scale testing, are given.
