ABSTRACT
Earthquakes and Wind forces pose significant threats to high-rise structures worldwide, often causing extensive damage and loss of life and property. Friction dampers are cost-effective, easy to install and reusable and hence are the best choice among several types of seismic dampers to control the effects of lateral forces on high-rise structures. The arrangement of the dampers plays a prominent role in strengthening high-rise buildings for lateral forces. The present study investigates the efficacy of X-type and diagonal friction damper configurations arranged at the bottom 1/3rd, middle 1/3rd, top 1/3rd and throughout the height in a typical bundled tube high-rise building system in minimizing the structural response to lateral forces. It is observed from the present study that the location of the friction dampers plays a prominent role in controlling structural response to the lateral loads compared to the type of friction dampers adopted. Building system with X-type friction dampers arranged throughout the height of a building is found to be effective in resisting lateral forces in bundled tube high-rise structural systems, especially at higher stories as compared to other configurations considered in the study.
