Seismic Response Study of Asymmetric Systems with Linear and Nonlinear Fluid Viscous Dampers
This investigation is concerned with application of nonlinear fluid viscous dampers for asymmetric-plan systems. For this purpose, the behavior of nonlinear fluid viscous dampers is summarized first followed by the effects of damper nonlinearity on seismic response of asymmetric systems. It is shown that the peak force in nonlinear damper tends to be smaller compared to linear damper. However, ...
متن کاملICCM2014 28-30 July, Cambridge, England PARAMETER IDENTIFICATION OF FLUID VISCOUS DAMPERS
This paper focuses on parameter identification of Fluid Viscous Dampers, comparing different existing literature models, with the aim to recognize ability of these models to match experimental loops under different test specimens. Identification scheme is developed evaluating the experimental and the analytical values of the forces experienced by the device under investigation. The experimental...
متن کاملImproved Seismic Performance of Chevron Brace Frames Using Multi-Pipe Yield Dampers
Spacious experimental and numerical investigation has been conducted by researchers to increase the ductility and energy dissipation of concentrically braced frames. One of the most widely used strategies for increasing ductility and energy dissiption, is the use of energy-absorbing systems. In this regard, the cyclic behavior of a chevron bracing frame system equipped with multi-pipe dampers (...
متن کاملFluid Viscous Dampers: an Effective Way to Suppress Pedestrian-induced Motions in Footbridges
In the civil engineering field, fluid viscous dampers, used extensively in military applications, have found commercial applications on buildings and bridges subjected to seismic and/or wind storm inputs. Because fluid damping technology was proven thoroughly reliable and robust, implementation on footbridges to suppress undesirable pedestrian-induced vibrations is taking place. . This presenta...
متن کاملApplication of a Direct Procedure for the Seismic Retrofit of a R/C School Building Equipped with Viscous Dampers
Several design methods aimed at sizing the viscous dampers to be inserted in building structures have been proposed in the last decades. Among others, the authors proposed a five-step procedure that guides the practical design from the choice of a target reduction in the seismic response of the structural system (with respect to the response of a structure without any additional damping devices...
