摘要

A previously proposed model for uniaxial loading of confined high strength concrete (HSC) is extended inthis paper to include cyclic loading. Parameters such as, compressive strength, volumetric ratio oftransverse reinforcement, yield strength of ties, tie spacing, and tie pattern, dissipation of energy throughthe hysteresis loops, stiffness degradation as damage progresses, degree of confinement, and ductility areall taken into account. Comparison of the results from finite element analysis using ADAPTIC, in whichthe proposed material model is implemented, against experimental results demonstrated good agreement,thus paving the way for much needed parametric studies on the behavior of structures made of HSC.
