Performance of reinforced concrete walls with dampers under the influence of earthquakes in the near and far regions

In this article, the behavior of high-rise coupled reinforced concrete walls subjected to earthquakes in the near and far domain has been investigated. In this system, there is no ordinary reinforced concrete coupler beam and the coupler action is done with buckling restained type braces with and without viscous dampers, which in addition to the consumption of seismic energy, cause a pair of axial forces in the foundations of the wall. The structures are designed according to the regulations and then the nonlinear model of the reinforced concrete wall is prepared using fiber elements. Seismic responses of structures such as drift between floors, ductility of curvature of wall foundations, coupling ratio, displacement and shear requirement of the responses under the two types of records mentioned are investigated and compared. On average, the results show that the inter-floor drift ratio for systems without dampers is about 22% higher than for systems with dampers.
