ELASTIC-PLASTIC ANALYSIS OF RC SHEAR WALL USING DISCRETE ELEMENT METHOD
Abstract:
An analytic method of RC structure using discrete element method is introduced in this paper. The RC structures are meshed with concrete discrete elements and re-bar elements. The discrete elements are connected with “point to point” contact elements and spring elements. The damage of concrete is assumed that it only happens on the interfaces of different discrete elements. Hence, the contact estimation of traditional discrete element method is simplified and the stability and speed of calculation process is improved. The influence of crack surfaces also can be obtained in this method, which is difficult for normal finite element method. A two-limb shear wall model is analyzed using this method. The results show this method is rational and effective.
