Assessment of Energy Dissipation Capacity of Steel Moment Resisting Frames Under the Effect of Earthquake

Abstract

In recent years, earthquake engineering was introduced and showed the path for energy concepts, these concepts have applications in evaluating the vulnerability of the structures under earthquake vibrations and also in optimization design. Now-a-days, energy dissipation capacity is estimated by either empirical equations or experimental way which are not sufficient and considered effective for the study and also numerical analysis which is considered difficult to use in practice. In the present study, nonlinear dynamic analysis is obtained to investigate the distribution of damage and dissipation capacity in the structure and also to find out the maximum storey drift and storey displacement. The main aim of this study is to evaluate the energy dissipation capacity of steel moment resisting frames under earthquake motions. The more the structure height increases, the dissipation capacity increases. The stress levels at top stories are high which are controlled by potential and kinetic energy and balanced with damping.
