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...
متن کاملComparisons between Ambient and Forced Vibration Experiments
The ambient and forced vibration techniques for testing full-scale structures are critically compared. Both methods, based on small level excitation, may be used to determine many mode shapes and frequencies of vibration and the corresponding damping values, with adequate accuracy for most purposes. The two techniques give mutually consistent results. The mode amplitudes determined by ambient a...
متن کاملOptimization of Tuned Mass Damper Parameters Using Evolutionary Operation Algorithm
Optimum parameters of Tuned Mass Dampers (TMD) are determined in this paper to minimize dynamic response of a multi-storied building system. The response of the structural system is simulated under lateral excitation. To optimize dynamic parameters of the TMD system for minimum top deflection of the structure, a numerical global optimization algorithm called Evolutionary Operation (EVOP) is use...
متن کاملThe Multi-Degree-of-Freedom Tuned-Mass Damper for Suppression of Single-Mode Vibration Under Random and Harmonic Excitation∗
Formulas for the optimal design of single-degree-of-freedom (SDOF) tuned-mass dampers (or dynamic vibration absorbers) for SDOF structures under random and harmonic excitations have been available for many years. Whenever an absorber body is attached to a primary system, there is potential for utilization of motion in more than one degree of freedom of the body relative to the primary system. I...
متن کاملThe Two-Degree-of-Freedom Tuned-Mass Damper for Suppression of Single-Mode Vibration Under Random and Harmonic Excitation
Whenever a tuned-mass damper is attached to a primary system, motion of the absorber body in more than one degree of freedom (DOF) relative to the primary system can be used to attenuate vibration of the primary system. In this paper, we propose that more than one mode of vibration of an absorber body relative to a primary system be tuned to suppress single-mode vibration of a primary system. W...
