【Abstract】 An elastic-plastic damage element is developed on the basis of the concepts of damage mechanics and plasticity theory.And DAMAGE2D is compiled for the nonlinear analysis of RC frame according to the damage element.Examples illustrate that the nonlinear analysis results of RC frame have a satisfactory precision by use of the elastic-plastic element.Furthermore,the frame structure is divided into different damage stages according to the calculation results.And the results can be applied to the seismic analysis based on pushover method.更多还原
