Nonlinear modeling scheme is proposed for reinforced masonry building structures, from component(shear wall) to structure level. For the reinforced masonry shear walls, both flexure and shear dominated walls are considered. In flexure-dominated walls, material models are described for both masonry and reinforcement. In the model of reinforcement, the effects of hysteresis behavior, fracture and buckling are considered, while in the masonry model, the crushing effect is considered. In the shear model, a nonlinear spring is provided with parameters calibrated according to the available test data. Comparison between experimental data and simulation is conducted for both shear-dominated and flexure-dominated walls. Furthermore, The building system model with the proposed model is analyzed under different level of earthquake ground motions.
