Abstract: Two high-performance fiber reinforced cement composite (HPFRCC) low-rise walls with a height-to-length ratio of 1.3 were tested under displacement reversals to investigate the feasibility of using fiber reinforced cement-based materials to improve the displacement capacity of low-rise walls when subjected to seismic excitations. The main experimental parameter studied was the influence of the fiber reinforced material on the behavior of low-rise walls. Specimen W1 contained ultrahigh molecular weight polyethylene fibers (Spectra) in a volume fraction of 1.5%, and Specimen W2 had steel hooked fibers in a 2.0% volume fraction. Both walls exhibited stable hysteretic response with displacement capacities exceeding 2.0% drift. Test results showed that the use of fiber reinforced cement-based materials in low-rise walls could lead to a relaxation of distributed vertical and horizontal reinforcement requirements and, more importantly, to a substantial enhancement in drift capacity, which is limited for the case of reinforced concrete low-rise walls.
