shear lag comparison in tall buildings with different structural systems

In this paper, Near fault earthquakes compared to far-fault earthquakes have greater potential to create damage in structures. In this paper, the effect of far fault and near fault events on structural response of reinforced concrete shear wall besides buckling restrained brace frame in tall and mid-rise buildings is studied. In the modeling, the specification of the reinforced shear wall and the buckling restrained frames is used. This kind of structural system is essentially a combined system. In this study, the structural system of the considered buildings is designed by using the valid cods and using response spectrum analysis method. Then, the nonlinear model is prepared. In the numerical model of the walls, the fiber type elements is used. In the numerical model of the walls, the fiber type elements is used. The nonlinear time history analysis is implemented subjected to the far fault and near fault earthquakes. Finally, the responses of the structures are analyzed and compared.
