Abstract

This paper presents a brief overview of research being conducted in the area of Seismic Hazards Mitigation. The focus of the study has been on the development of integrated model of a structure with controllable fluid damper. The damper is used with an objective of reducing the dynamic wave propagation potential in the structure, upon the structural excitation. Before its employability to serve the intended purpose, the system identification and the model validation are the pre-requisites for the optimal functioning of the damper. A phenomenological model of the controllable fluid damper-Magnetorheological damper is used along with other Smart materials in the experiments conducted under controlled conditions. The experimental results are used to verify the integrated system model. The experimental results obtained indicate that high performance can be attained with controllable fluid damper to meet the requirements associated with seismic response reduction in civil engineering structures.

Some Experimental Investigations for the Development of Integrated Model of a Structure with the Controllable Fluid Damper

Arlington, Virginia

This paper presents a brief overview of research being conducted in the area of Seismic Hazards Mitigation. The focus of the study has been on the development of integrated model of a structure with controllable fluid damper. The damper is used with an objective of reducing the dynamic wave propagation potential in the structure, upon the structural excitation. Before its employability to serve the intended purpose, the system identification and the model validation are the pre-requisites for the optimal functioning of the damper. A phenomenological model of the controllable fluid damper-Magnetorheological damper is used along with other Smart materials in the experiments conducted under controlled conditions. The experimental results are used to verify the integrated system model. The experimental results obtained indicate that high performance can be attained with controllable fluid damper to meet the requirements associated with seismic response reduction in civil engineering structures.
