Seismic Vibration Control on Reinforced Concrete Structure with Multiple Tuned Mass Damper Considering SSI Effects

Abstract

An earthquake causes a great deal of damage to the structure, that’s why many researchers work on the vibration of the structures caused by the earthquake. A fifteen-story reinforced concrete structure with MTMD (multiple tuned mass dampers) is modeled with a fixed and flexible base in SAP 2000. And also deals with the analysis of the structure and the comparison of the Natural periods, Storey displacement, and Base shear of building values under the dynamic condition considering SSI effects. The paper concluded that the natural periods increase when the soil-structure interaction effect is considered as compared to the assumption of fixed support and the story displacements increase when the soil-structure interaction effect is considered as compared to the assumption of fixed support. The analysis of this structure yielded better results under the conditions used by the multi-tuned mass damper.
