Seismic response of building structures with dampers in shear walls

摘要

When buildings are subjected to earthquakes, it is imperative to dissipate some of the input energy through predetermined and well designed mechanisms. This study investigates the influence of mechanical control on structural systems through the application of strategically located component elements with reliable damping and stiffness properties that can modulate the response. The effects of installing such dumping elements at two particular locations have been investigated. These positions are between the shear walls near the coupling beams and within cut out sections of the wall elements in multi-storey structures. Finite element time history analysis is used in the study and results indicate that the proposed procedure is able to achieve reasonable improvements in seismic response.
