Esta dissertação propõe uma solução padronizada de aplicação de Tuned-Mass Damper (TMD) para controle de vibrações em lajes baseada na análise das características de carregamentos associados à utilização humana e nas características estruturais mais comuns à engenharia contemporânea. De modo a simplificar sua aplicação técnica, a sintonização é proposta por meio da escolha de componentes pré-determinados para a montagem do TMD e pela distribuição e posicionamento dos mecanismos.

Abstract:

Il presente elaborato affronta lo studio dinamico di un dispositivo a massa accordata (TMD) innovativo che, accoppiato ad una struttura, migliora l’attenuazione delle vibrazioni rispetto ad un TMD classico. Questo dispositivo sfrutta l’amplificazione inerziale (IAM). È costituito da un oscillatore semplice, accoppiato a due masse laterali. Se progettato correttamente, le masse laterali sono capaci di amplificare l’inerzia effettiva del risonatore. In particolare, nel capitolo 1 verranno riassunte le nozioni fondamentali dell’isolamento sismico e della dissipazione. Si introdurrà lo smorzatore

Abstract:

Since their invention in the early 1900s, Tuned Vibration Absorbers (TVAs) have shown to be effective in suppressing vibrations of machines and structures. A vibration absorber is a vibratory subsystem attached to a primary system. It normally consists of a mass, a spring, and a damper. Mounted to the primary system, a TVA counteracts the motions of the primary system, "absorbing" the primary structure's vibrations. A conventional passive TVA, however, is only effective when it is tuned properly, hence, the name "tuned" vibration absorber. In many practical applications, inevitable off-tu

Atualmente as estruturas estão sendo avaliadas para um maior número de ações em relação há algumas décadas. Esta melhoria ao longo da fase de concepção é dada devido ao fato de que está se tornando mais competitivo o fornecimento de estruturas leves e esbeltas, sendo solicitados, cada vez mais, projetos com menor custo de implantação. Devido a isto, é necessário avaliar as estruturas não apenas sujeitas a cargas estáticas, mas também a carregamentos dinâmicos.

A device can be installed to prevent these vibrations.In this thesis, we study the response of buildings and lateral vibrations of footbridges equipped with Tuned Liquid Damper.

This thesis explores next generation passive and semi-active tuned mass damper (PTMD and SATMD) building systems for reducing the seismic response of tall structures and mitigating damage. The proposed structural configuration separates the upper storey(s) of a structure to act as the 'tuned' mass, either passively or semi-actively. In the view point of traditional TMD system theory, this alternative approach avoids adding excessive redundant mass that is rarely used. In particular, it is proposed to replace the passive spring damper system with a semi-active resetable device based system (SAT

Abstract:

Abstract The tuned mass damper (TMD) is a well-known and approved concept for resonance vibration control. However, as a fully passive device, the traditional TMD has a limited operating band and rather poor robustness against parameter variations. To overcome these weaknesses, a semi-active control can be applied to TMD. As a result, a more effective and flexible device can be attained. In theory, the application of the semi-active scheme is straightforward and the gain in performance is considerable. In practice, however, the non-idealities associated with actuators and control systems degra

This study developed a temperature controlled semi-active tuned mass damper (TMD) using shape memory alloy (SMA) for civil structural applications.

The effect of in-service temperature on SMA can provide adaptive dynamic properties to TMD. Therefore, the natural frequencies can be adjusted to an optimal range. In this thesis, the material characterisation of SMA is studied through acting dynamic cyclic loading. It was found

碩士<br>國立成功大學<br>土木工程學系<br>102<br>The friction-type tuned mass damper system (FTMD) is adopted in this thesis as the target for implementing the hybrid testing technique. Firstly, the shaking table tests of the FTMD controlled by high/low friction setups are conducted. The vibration suppression of the main structure equipped with the FTMD subjected to earthquake loading can be investigated and ensured. Secondly, the main structure is replaced by its numerical model and is embedded inside the hybrid testing configuration. The total shear force estimated from the inertial force calculated from th

Abstract:

碩士<br>國立中興大學<br>土木工程學系所<br>96<br>Multiple tuned mass dampers (MTMD) are structure control systems that composed by many masses, dampers and springs. The purpose of MTMD is to make the natural frequency of MTMD tuned with that of the main structure for changing the dynamic characteristics of the main structure. MTMD can reduce the dynamic response and increase the safety and availability of the main structure. Many schemes for designing optimal parameters of MTMD have been proposed and developed very well. However, there are few researches compare and analyze the difference among these schemes.

Abstract:

碩士<br>國立中興大學<br>土木工程學系所<br>103<br>A Tuned Mass Damper (TMD) system consists of an added mass with properly functioning spring and damping elements that provide frequency-dependent damping in a primary structure. By attaching a TMD to a structure, vibration energy of the structure can be transferred to the TMD and dissipated via the damping mechanism in the TMD. Although the design and application of traditional linear TMD systems are well developed, nonlinear TMD systems that may lead to better control performance are still in the developmental stage. The control performance of a traditional T

Abstract:

碩士<br>國立中興大學<br>土木工程研究所<br>82<br>Previous researches on reduction of structural responses using PTMD (Passive Tuned Mass Damper) did not take the effect of damper strokes into consideration in some cases, strokes of damper might exceed the allowable working space. To overcome this unrealistic situation, a control force can be applied on the device of PTMD to reduce both structural responses and the damper strokes. This research investigates how the structural properties are changed and how

Abstract:

The subject of this study is the vibration isolation effect of linear and nonlinear hysteretic single degree of freedom oscillators attached to a structure. The system of oscillators, attached to the main structure, reduce the amplitude of its structural response, over a wide frequency band excitation. This is achieved by distributing the natural frequencies of the attachments over an a priori specified frequency interval, which is related to the excitation power spectrum density. In order to introduce hysteretic restoring force to the oscillators and study its effect to the vibration reductio

Then, the results are used to develop the fuzzy sliding mode control(FSMC) in active tuned mass damper (TMP) control system. It is desired that the structure under control can be sustained in safety and stability during external disturbances. 　　The control rule is difficult to derive from the classical control theory for building structural control system using active TMD. Furthermore, the improper control force may cause resonance and failure of the structure. It can''t b
