| Abstract: | The response of RC flexural member under cyclic loading is investigated in this paper by using FEM nonlinear analysis method. The nonlinear behavior of concrete and the crack surface effect are considered. Eight types of concrete elements are discussed according to the forms of cracks in the processing of cyclic loading. A FORTRAN program is developed to calculate the whole responses of a cantilever beam under cyclic loading. The hysteresis curves and the crack pattern of concrete cracks are obtained. The hysteresis curves and the crack pattern show reasonable agreements with test results. |
