【Abstract】 In this paper,the distinct element method (DEM) is applied to analyze the nonlinear static analysis of RC members,and the distinct element model for reinforced concrete members is developed,which is named as segment-multi-spring model (SMSM).A program is also developed in this paper for the nonlinear static analysis of RC columns on the basis of SMSM,to analyse the response of reinforced concrete columns under monotonic and cyclic horizontal loads.The numerical results prove that the SMSM is reliable,and the application of the DEM on RC structures is practicable.The application range of DEM is greatly enlarged in this paper.更多还原
