    • Abstract
  • The fiber-reinforced concrete(FRC) is characterized with a tensile strain-hardening behavior and numerous micro-cracks development. In order to reduce the amounts of stirrups, the FRC was used in the core of a beam-column joint. The compatibility equation, equilibrium equation and constitutive laws were established to analyze the force behavior of an FRC beam-column joint due to earthquake. A shear stress-strain skeleton curve model was presented, and the calculation method of shear stress and shear strain of crack point, yield point and peak point were studied. The comparison between theoretical calculation results and experimental results shows that the proposed model for shear stress-strain calculation is in a good agreement with the shear stress-strain relationship of an FRC beam-column joint under earthquakes.
