Research Abstract

Experimental and analytical investigations were conducted on the mechanical characteristics of hybrid RC members reinforced by continuous fibers. The members consisted of different kinds of reinforcement with respect to strength, elastic modulus, hysteric response and ductility. The properties related to flexural, shear and bond characteristics were mainly discussed. Carbon fibers were more effective than aramid fibers to reinforce concrete members, because the high elastic modulus of carbon fibers performed to prevent expanding of cracks. Conventional formulas recommended in AIJ guidelines or formulas by modified compression field theories overestimated the shear strength of hybrid RC members. However, analysis based on truss analogy combined with sector truss mechanism considering bond stress distribution along main steel rebar well-predicted experimental results, Experimental and analytical investigations were also conducted to study development of damages in hinge zones of reinforced concrete columns. Sufficient confinement for hinge zones was significantly effective to control the deterioration of bending moment capacity to be small. Simple inelastic section analysis considering confinement for concrete predicted the observed moment vs. curvature and axial strain vs. curvature relationships precisely. Accurate formula to estimate anchorage strength of main rebar anchored mechanically into RC members was proposed in case of side-splitting failure of concrete around the rebar.
