Using the high precision plane elements with ratational degree of freedom, a finite element model for reinforced concrete coupled walls is founded to analyse the process of crack and yield under cycle load. Also, a more accurate method of anti-seismic design for reinforced concrete coupled walls is presented.
Keywords: coupled wall; reinforced concrete; elasto-plastic; cycle load; rotational degree of freedom
