Seismic Enhancement of Steel Moment Resisting Frame. With Hybrid Damping System

      Аннотация: Reinforced Cement Concrete (RCC) construction is a well-known form of building construction in Civil Engineering industry worldwide. But due to its weak performance during seismic events, this form is under revision or research. Steel moment resisting frame (SMRF) with deck slab is a new trend construction technique, which is attracting technocrats working in Structural Engineering field. High ductility and ease in modification and maintenance, makes them more popular as compared to RCC structure nowadays in earthquake prone areas. The energy dissipation capacity of the structure can be improved by installing energy dissipaters into the structures. The SMRF enhanced with passive energy dissipaters are investigated for earthquake response and energy dissipation capacity and an innovative approach of design of these systems is recommended in this research work. . The ten storied steel structure is analyzed by nonlinear time history analysis, with incremental dynamic loading of seven earthquake ground motion time history records, which are scaled to achieve a set of results and then compared with various possibilities.
