Enhanced motion control performance of the tuned mass damper inerter through primary structure shaping

Assessing the effect of nonlinearities on the performance of a tuned inerter damper

Real time tuned mass damper simulation system

The major concern in the construction industry in constructing tall structures is vibration due to wind and earthquake. Tuned mass dampers are an effective and practical ways to reduce the effect of vibration in structures. This thesis presents a tool, which simulates the effect of tuned mass dampers on the structure. This tool has been proposed to form a part of the website, moment.mit.edu. Ja...

The Effect of Tuned Mass Damper on Seismic Response of Building Frames with Uncertain Structural Characteristics

Tuned mass dampers (TMDs) could be used to absorb the input energy of the applied load, and reduce the response of the building frames. However, the effectiveness of TMD in reducing the response of the building frames could be affected by inherited uncertainties in the structural characteristics of the frames. In this study, in order to investigate the probabilistic response of steel moment-res...

Reduction of Wind Induced Motion Utilizing a Tuned Sloshing Damper

Serviceability of buildings is affected by excessive acceleration experienced at the top floors in wind storms that may cause discomfort to the occupants. To ensure functional performance of tall buildings it is important to keep the frequency of objectionable motion levels below the discomfort threshold. This paper addresses a new approach that facilitates mitigation of wind induced motion of ...

Comparative Performance Study of Tuned Liquid Column Ball Damper for Excessive Liquid Displacement on Response Reduction of Structure

The tuned liquid column damper (TLCD) having a uniform cross-sectional tube of U-shaped, occupied with liquid is used as a vibrational response mitigation device. The tuned liquid column ball damper (TLCBD) is a modified TLCD, where, an immovable orifice, positioned at the middle part of the horizontal portion, is replaced by a metal ball. Different studies on the unconstrained optimization per...
