Proposed Configurations for the Use of Smart Dampers with Bracings in Tall Buildings

Abstract EN

This paper presents wind-induced response reduction in a very slender building using smart dampers with proposed bracings-lever mechanism system.

The building presents a case study of an engineered design that is instructive.

The paper shows that shear response and flexural response of tall buildings present two very different cases for vibration suppression.

Smart dampers are implemented optimally in the building to reduce its response in the lateral directions for both structural safety and occupant comfort concerns.

New bracings-lever mechanism configurations are proposed for the dampers to improve their performance.

The study shows how the proposed configurations can enable application to flexural response and scenarios where the interstory drift is not enough for dampers to work effectively.

In addition, a decentralized bang-bang controller improved the performance of the smart dampers.
