Abstract:High-Performance Fiber Reinforced Cocndrete (HPFRC) exhibits features particularly desirable for increasing earthquake resistance such as high tensile strength and ductility. However, since HPFRC is substantially different from conventional materials, using existing design and construction procedures does not lead to the most cost-effective solutions. To address this issue, this paper presents a way of selectively using Slurry Infiltrated Mat Concrete (SIMCON), Slurry Infiltraded Fiber Concrete (SIFCON) and high Strength Lightweight Aggregate Fiber kReinforced Concrete (HS_LWA FRC) to construct is to improve cost effectiveness by simplifying both construction and postearthquake repair, increasing the construction speed, lowering seismically induced forces and increasing overall seismic resistance. This is achieved by fuses with cast in place HS-LWA FRC. First, the paper presents experimentally evaluated behavior of HPCF members. Next the seismic response of a four story HPCF building is investigated analytically and compared to that of a seismically designed R.C. frame. HPCF reached an overall good seismic response. As compared to the reference building, it exhibited slower strength and stiffness degradation, lower top displacements and story drifts. Overall building damage was lower for the HPCF building, and even under 33% higher seismic excitations the HPCF building had higher seismic resistance than the reference R. C. Building.
