A new vibration control device called a rotational inertia double-tuned mass damper (RIDTMD) is proposed in this paper. The device consists of a tuned mass damper (TMD) in which the typical viscous damper is replaced with ...

In this research the comprehensive development of a long-stroke MR-damper designed to control the earthquake performance of an existing 21-story reinforced concrete building in Santiago (Chile) by reacting on one of its ...

The first low-cost tuned mass damper system in Chilean building construction was recently designed and included on a 21-story plus 6-basement building. The structure is an example of the so-called Chilean free-plan building ...

This research investigates the seismic and harmonic response of a true free-plan tall building equipped with two tuned pendular inertial masses (TMs) and magnetorheological (MR) dampers. Construction of this proof-of-concept ...

This research studies the response of asymmetrical linear and nonlinear structures subjected to unidirectional and bidirectional seismic excitation, equipped with one or two Tuned Mass Dampers (TMDs). The optimized parameters ...

This article deals with the development of a long-stroke MR-damper aimed to control, by reacting on a tuned mass (TM), the earthquake performance of an existing 21-story office building located in Santiago, Chile. The +/- ...

A scaled prototype of an MR damper was active in passive mode on a 160 ton tuned mass in a 21-story building in Santiago, Chile, during the February 27, 2010 earthquake. More recently, a full scale ±100 cm stroke MR damper ...

Passive tuned-mass dampers (TMDs) are a very efficient solution for the control of vibrations in structures subjected to long-duration, narrow-band excitations. In this study, a Bidirectional and Homogeneous Tuned Mass ...
