Earthquake Analysis of Reinforce Concrete Framed Structures with Added Viscous Dampers
This paper describes the development of a numerical finite element algorithm used for the analysis of reinforced concrete structure equipped with shakes energy absorbing device subjected to earthquake excitation. For this purpose a finite element program code for analysis of reinforced concrete frame buildings is developed. The performance of developed program code is evaluated by analyzing of ...
متن کاملEquivalent Damping Ratios of Structures with Supplemental Viscous Dampers
The current design formulas such as those provided by FEMA273/274 for building structures with supplemental viscous dampers were derived based on the shear building assumption. However, for medium-rise to high-rise buildings that deform in a combined form of shear and bending when subjected to seismic loading, the design using existing formulas may result into an actual damping ratio much lower...
متن کاملSeismic 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 کاملParametric Non-Linear Analysis of Reinforced Concrete Frames with Supplemental Damping Systems
Abstract—This paper focuses on parametric analysis of reinforced concrete structures equipped with supplemental damping braces. Practitioners still luck sufficient data for current design of damper added structures and often reduce the real model to a pure damper braced structure even if this assumption is neither realistic nor conservative. In the present study, the damping brace is modelled a...
متن کاملThe Effect of Viscous Dampers on Improvement of the Behavior of Tall Belt Truss Structures
Using energy absorption systems in the structures with malfunctioning components is of paramount importance. By absorbing the seismic energy, these systems help the components of the structure to remain resilient during earthquake. In the present study, viscous dampers were applied in order to enhance the reactions of tall building with belt truss. To assess the response of a structure under e...
