Numerical evaluation of cyclic performance of damaged RC frames using passive devices

Abstract

Metallic yielding device is one of the passive energy dissipation devices. It has good energy dissipation capacity, high initial stiffness along with high ductility. In this study, 0.4-scale single-story single-bay non-ductile gravity load design frame has been tested under cyclic load; later on, the damaged frame has been strengthened with the help of steel caging and metallic yielding damper. In this paper, the experimental results are validated numerically using OpenSees. The numerical model has the capability of predicting of failure and nonlinear behavior of reinforced concrete frame. The numerical model predicted the hysteresis behavior, stiffness, and energy dissipation with adequate accuracy.
