Experimental Study to Control Vibrations in One Storied & Two Storied Building with and without TMD

A. V. Phalake

Abstract


ABSTRACT

Recently, there has been an increase in the number of high-rise buildings in the industry of construction that are flexible and have very low damping values. These structures are susceptible to failure by earthquakes and wind-induced structural vibrations. Therefore, today there are many techniques to reduce the vibrations of structures, the latest concept of which is the use of TMD. There are many theoretical studies of the behavior of buildings with tuned mass dampers under impact. However, experimental research in this area is very limited. In this paper, one-, two-, and three-story building framework models are developed for a vibrating table under sinusoidal excitation to observe the structural response with and without TMD. The TMD is tuned to the structure frequency for structure preservation. Stiffness and damping constants, frequency ratio, mass ratio, tuning ratio and other parameters. It is considered to observe the effectiveness and robustness of the TMD in terms of percentage reduction in the amplitude of the structure. From the study of the different parameters observed, the TMD can be used for the vibration control of structures.
