MICROPLANE MODEL FOR CYCLIC TRIAXIAL BEHAVIOR OF CONCRETE

In this study, the microplane model from a previous study (Bazant and Prat, 1988) is improved and extended to cyclic loading, as well as to the rate effect, which is important in cyclic loading. The new model is implemented in a 3-dimensional finite element code. In this paper, the results of several numerical studies are presented to demonstrate the capability of the microplane model in simulating the cyclic and rate effects in plain concrete. The studies presented include those on cycling in tension, cycling in compression, and cycling in shear. The cyclic finite element analysis including the rate effect is performed for the cases of the 3-point bending of a beam and the uniaxial compression test. The results of the numerical analyses are compared with test results.
