1. Aplicação de tuned-mass dampers para controle de vibrações em lajes
Resumo Este artigo propõe uma solução padronizada de aplicação de Tuned-Mass Dampers (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 sintoni

2. Effectiveness of Tuned Mass Dampers in Seismic Response Control of Isolated Bridges Including Soil-Structure Interaction
Abstract The effect of soil-structure interaction (SSI) on the dynamic responses of seismically isolated three-span continuous reinforced concrete (RC) bridge is investigated. Also, tuned mass damper(s) (TMD/s) is/are installed to control undesirable bearing displacement, even under the SSI effect. The TMDs are placed at the mid-span of the bridge and each t

3. Sensitivity Analysis of the Effectiveness of Tuned Mass Dampers to Reduce the Wind-Induced Torsional Responses
Abstract Use of Tuned Mass Dampers (TMDs) to reduce the wind-induced torsional response of structures has been investigated in the literature by assuming that the wind excitations can be approximated by harmonic forces or white noise random processes; however, such an assumption is not realistic. Further, wind load effects are correlated. This study is focus

4. Optimal configurations of composite multiple mass dampers in tall buildings
The effectiveness of multiple tuned mass dampers (MTMD) for suppressing harmonically forced oscillations is studied in the paper. In particular the influence of possible connections between the masses of the damper on the main system performance is investigated using four different configurations of a double mass damper. For this, a minimax procedure, which

5. Estudo em túnel de vento dos efeitos de atenuadores dinâmicos sintonizados em modelos de edifícios altos
Com a crescente necessidade de projetos cada vez mais econômicos, bem como a valorização dos terrenos nos grandes centros urbanos, que leva a conseqüente necessidade de aumentar o aproveitamento destes, e com o desenvolvimento das técnicas construtivas e dos processos de análise estrutural, as edificações tornaram-se mais altas, leves, flexíveis, me

6. Controle de vibrações em edifícios submetidos à ação de cargas dinâmicas utilizando amortecedor de massa sintonizando na forma de pêndulo / Vibration control of structures subjected to dynamic loads using tuned pendulum-shaped mass dampers
The ongoing progress of structural analyses and dimensioning, in addition to the continuous advancements in building techniques and material, has made it possible to build taller and more slender structures every day. These structures are also more vulnerable to excessive vibrations caused by dynamic loads like earthquakes, winds, waves, intense traffic, and

7. Controle da Resposta Dinâmica de um Passarela de Pedestres da Cidade de Brasília com a Utilização de Amortecedores de Massa Sintonizados / Vibration control of a footbridge in the city of Brasilia using multiple tuned mass dampers (AMSM)
Advanced constructive technologies and the use of high resistance materials made possible the design of slender and flexible structures, which present less strength and damping. These structures are more sensitive to vibrations in low frequencies, characteristic of footbridges. The loads produced by human movements, mathematically represented by periodic fun
