摘要：

Presently, earthquake-resistant design provisions are based on the assumption of inelastic behaviour of structures in major earthquake occurrences. It is generally possible to achieve ductile behaviour with significant damage in steel and reinforced concrete structures. The passive control system is generally used to protect a building from the damaging effect of an earthquake. In the present work, the study of building with Base Isolated top floor as a tuned mass damper (TMD) is considered. The top storey is used as TMD for this purpose, the isolation system is provided at the base of the top storey of a building. This TMD being made up of concrete has the same damping ratio as that of the main building. Effectiveness of Base Isolated TMD is ascertained by comparing the results of the considered building of analysis by using Time History Analysis. By comparing the results, it is observed that Base Isolated TMD is quite effective as compared to building without TMD. © 2020, Springer-Verlag GmbH Germany, part of Springer Nature.
