A Seismic Analysis of R.C. Structures Under Tuned Mass Damper System.
Abstract: A Seismic Analysis of R.C. Structures Under Tuned Mass Damper System treats seismic force reduction of multi-storey buildings using embedded dampers. tuned mass damper is investigated. Dynamic analysis was carried out using Etabs to obtain the damped and undamped responses of the structure in terms of deflections at all storeys in order to evaluate the effectiveness of the damping system to reduce the seismic response. The earthquake zone v used …

Effectiveness of Semi-Active Variable Stiffness Tuned Mass Damper for Seismic Load Using LQR Control
Abstract: In this study, effectiveness of semi-active variable stiffness tuned mass damper in reducing seismic response of 10-story frame structure is evaluated. The variable stiffness device, comprising four spring, having rhombus configuration, adapted from literature is attached to the tuned mass damper. A control algorithm using state space form of governing equation of motion is developed. LQR controller is employed to obtain control force based on displacement and velocity response feedback. …

Vibration control of a Plan irregular RC framed structure under seismic excitations with the help of TMD along with bracings
Abstract: The study of dynamic behavior of high-rise structures is immensely important as the dynamic response of the structures due to natural forces like seismic forces, wind forces etc. may result in structural failure. An unsymmetrically located shear wall or similar kind of stiff element may cause the structure to have plan irregularity. Such type of plan irregularity in high rise structure can induce the torsional displacements in the structure subjected …

Experimental Study on Effectiveness of TMD in Reducing Torsional Motion under Harmonic Base Motion
Abstract: AbstractAsymmetry in the building could arise due to unsymmetrical distribution of mass, stiffness, damping and/or strength characteristics. The earthquake response of asymmetric buildings is characterized by coupling between translational and rotational degrees of freedom (dofs). This paper includes an experimental analysis of one storied asymmetrical building frame subjected to harmonic motion with and without tuned mass damper (TMD). Experimentation is done on a shake table and readings were recorded. The …

Differential Model of Wave Vibration on Strings and Rods
Abstract: Vibration, as a physical phenomenon, plays a multifaceted role in both natural and engineered systems. Beyond its essential contribution to communication through sound and speech, it finds critical application in various technological domains. For instance, in the design of stringed musical instruments such as violins and guitars, precise manipulation of string vibrations defines tonal quality and musical resonance. Similarly, metal rods in tuning forks exhibit vibrational properties that are finely …

Experimental Study on Effectiveness of MTMD in Reducing Structural Response of Multi-story Asymmetric model Under Harmonic Loading.
Abstract: The current trend toward construction of high rise building with the use of lightweight, high strength material and advance construction methods have led to making comparatively light and flexible structures, which have relatively low natural damping. Results make structures more prone to environmental excitation such as earthquake loads. An asymmetry in a building which may arise due to unsymmetrical distribution of stiffness, mass, damping and strength characteristics. The responses of …

Analysis of Two way Continuous Bridge under Moving Loads
Abstract: The analysis of dynamic behavior of bridge structures that are subjected to moving loads has been one of the research interests in recent years. Specifically in railway bridges, Resonance occurs when the load frequency is equal to a multiple of natural frequency of the structure. Resonance vibrations have been observed in railway bridges especially subjected to High Speed Lines. They are caused mainly because of two reasons one is the …

Parametric Study of Tuned Liquid Damper on Multistorey Frame Unit
Abstract: Swimming pools in a skyscraper are not only an entertainment facility but also a boon of a structural design engineer to curb the impact of lateral forces such as wind, earthquake, etc. The usage of swimming pools as liquid tuned damper is a cost effective alternative without having any additional component within the structure. Much of the research to damp the vibration of the structure like base isolation, bracing, in-fills …
