Use of Dampers in Vertical cities: Effective Method to Control Seismic Vibrations

Modern high rise buildings, vertical cities, sky scrapers are popular due to its advantages in terms of consuming less foot print area of site; however this vertical development should be verified to safeguard the structure. To achieve this considering various parameters like structural systems, seismic vibration controlling systems and maintaining overall ductility of the structure are most important. This paper mainly reviews and discusses one of such method to control seismic vibrations i.e. use of dampers. Dampers of various types and mechanisms are studied. Case studies of top 5 skyscrapers in the world are discussed which includes Jeddah Tower, Burj Khalifa, Taipai tower, Shanghai Tower and International Commerce Centre. Concluding remarks are made with possible use of these dampers considering their suitability and requirement under various circumstances.
