Performance-based Design of RC Frame Buildings with Metallic and Friction Dampers

Performance-based Design of RC Frame Buildings with Metallic and Friction Dampers Supplemental energy dissipation is a technique of earthquake resistant design and for improving the seismic performance of existing buildings. In the present study, a comprehensive design methodology for performance based design of frame buildings with metallic and friction dampers has been proposed. In this study, the target performance level is aimed to achieve both in terms of inter-storey drift and plastic hinge rotation. A non-iterative step-by-step design procedure is proposed to achieve the target performance level. The methodology provides the design yield forces in case of metallic dampers, and slip forces in case of friction dampers. A satisfactory distribution of both types of dampers along the height of the building is also provided in the methodology. The efficiency of the proposed design methodology is validated by applying to a ten storey building and performing nonlinear time history analysis. The building, with and without dampers, is subjected to five spectrum compatible time histories with peak ground acceleration of 0.24 g and the relative performance of the building with the two types of dampers is studied. http://www.deepdyve.com/assets/images/DeepDyve-Logo-lg.png Journal of The Institution of Engineers (India): Series A Springer Journals

Abstract

Supplemental energy dissipation is a technique of earthquake resistant design and for improving the seismic performance of existing buildings. In the present study, a comprehensive design methodology for performance based design of frame buildings with metallic and friction dampers has been proposed. In this study, the target performance level is aimed to achieve both in terms of inter-storey drift and plastic hinge rotation. A non-iterative step-by-step design procedure is proposed to achieve the target performance level. The methodology provides the design yield forces in case of metallic dampers, and slip forces in case of friction dampers. A satisfactory distribution of both types of dampers along the height of the building is also provided in the methodology. The efficiency of the proposed design methodology is validated by applying to a ten storey building and performing nonlinear time history analysis. The building, with and without dampers, is subjected to five spectrum compatible time histories with peak ground acceleration of 0.24 g and the relative performance of the building with the two types of dampers is studied.
