A Simple Macro-Model to Predict the Nonlinear Behavior of RC Shear Walls

This study investigates the effectiveness of a simple macro-model in predicting the nonlinear response of reinforced concrete shear walls. The model consists of nonlinear spring elements representing Flexural and shear behavior. The Flexural behavior of the model is based on the uniaxial behavior of the vertical spring element. The shear behavior is based on a trilinear force-displacement backbone curve assigned to each horizontal spring element the model was implemented in ABAQUS6.6 to allow comparison between experimental and analytical results for test specimens with different shear-span ration. The model turned out to be capable of simulating the nonlinear behavior of the specimens at different stages of loading to a very good degree of accuracy and after a few seconds of CPU time.
