[S02A-03] Effect of Bond Constitutive Law between Reinforcement and Concrete on Hysteresis Characteristics of Uniaxial Tensile Members
Keywords: Bond Constitutive Law, Uniaxial Tensile Member, Finite element analsys
An efficient finite element analysis method was constructed in which concrete was modeled separately using a plastic damage model and a non-linear hysteresis spring between the reinforcing bar and concrete. Numerical analyses reveal that the unloading curve and directing point by low-cycle cyclic loading analysis of uniaxial tension members and the reduction rate of concrete stress during high-cycle loading are generally consistent with previous experimental results.
