Abstract

Abstract

It was conducted an experimental investigation on four steel fiber reinforced high-strength concrete frame exterior joints under the low cycle loading,and discussed the influence of steel fiber volume ratio and stirrup ratio on seismic capacity of the joint of this type.The result shows that with the increase of the steel fiber volume ratio and stirrup ratio,the restriction role to the concrete of the core area of the joint was enhanced; the shearing-resistance capacity of the core area of the joint was increased; the degeneration degree of shearing-resistance capacity and rigidity was mitigated; joint core area shearing deformation was reduced; the joint ductility was increased and the energy dissipation capacity of the joint was improved．
