000011523 520__ $$2eng$$aAs a kind of Ductile Fiber Reinforced Cementitious Composites (DFRCC), Hybrid Fiber Reinforced Cement-based Composites (HFRCC) have been developed. HFRCC includes two kinds of fibers, which are short and thin synthetic fibers such as Polyethylene or Polyvinyl Alcohol fibers and long fibers such as steel cords. Short fiber reinforces micro cracks while long does mezzo cracks, so that cracks disperse and each fiber works in different strain level. By applying HFRCC instead of Concrete to structural members, not only improvement of structural performance but also mitigation of damage under seismic loads would be expected. In this paper, static cyclic tests of columns are carried out to investigate seismic capacity and effect of damage control of HFRCC. Variables of test specimens are materials, the quantity of lateral reinforcement, and axial load condition. Usage of HFRCC are concluded as improvement of structural performance such as ductility, shear resistance, axial load carrying capacity, mode of failure, and damage level due to multiple cracks, pseudo strain hardening, and ductile tensile behavior by experimental study. Furthermore, it is shown that shear resistance and load carrying capacity can be evaluated by adding the effect of tensile strength of HFRCC to lateral reinforcement strength of conventional design formula.
