要旨 As post-peak mechanics of concrete structures is highly time dependent in general, constitutive modeling of softened concrete under short-term straining is thought to serve collapse analysis of higher accuracy. The main objective of this research is to propose a time dependent constitutive model for hardened concrete under short-term uniaxial cyclic loadings, which cover both pre- and post-peak regions in compression. Towards better evaluation for structual performances, the coupled elaso-plastic-damaging law in both time and strain paths is presented. Derivation of constitutive laws from experiment is discussed and its verification is performed under arbitral loading paths.
