13. Finite element analysis of high modal dynamic responses of a composite floor subjected to human motion under passive live load
Light weight and long span composite floors are common place in modern construction. A critical consequence of this application is undesired vibration which may cause excessive discomfort to occupants. This work investigates the composite floor vibration behavior of an existing building based on a comprehensive study of high modal dynamic responses, the rang

14. Dynamic response of low frequency Profiled Steel Sheet Dry Board with Concrete infill (PSSDBC) floor system under human walking load
This paper investigates the dynamic response of a composite structural system known as Profiled Steel Sheet Dry Board with Concrete infill (PSSDBC) to evaluate its vibration serviceability under human walking load. For this point, thirteen (13) PSSDBC panels in the category of Low Frequency Floor (LFF) were developed using Finite Element Method (FEM). The na

15. PROPRIEDADES FÍSICO-MECÂNICAS DE CHAPAS AGLOMERADAS PRODUZIDAS COM BAMBU, PINUS E EUCALIPTO. / PHYSICAL AND MECHANICAL PROPERTIES OF PARTICLEBOARD PRODUCED WITH BAMBOO, PINE AND EUCALYPT.
This study investigated the physical and mechanical properties of particleboards formed of bamboo (Bambusa tuldoides), pine (Pinus taeda) and eucalyptus (Eucalyptus grandis) and their combinations. To this end, panels were made, defined by the use of each type of particle pure or mixed by two or three being set 0, 25, 50, 75 and 100% of dry weight proportion

16. Structure-borne transmissibility evaluation through modeling and analysis of aircraft vibration dampers
Abstract In the aircraft industry a great practical relevance is given to the extensive use of vibration dampers between fuselage and interior panels. The proper representation of these isolators in computer models is of vital importance for the accurate evaluation of the vibration transmission paths for interior noise prediction. In general, simplified mode

17. Análise tipológica de elementos e sistemas construtivos pré-moldados de concreto do ponto de vista de sensibilidade a vibrações em serviço / Typological analysis of precast concrete elements and building systems in terms of sensitivity to vibration in service
In the context of construction modernization, the application of precast concrete elements offers a good and reliable alternative in the construction strategy, among them large spans, fast assembly, lightweightness and excellent structural members quality. Dealing about dynamic behavior of concrete structures, precast elements are subjected to several loadin

18. Mode localization of modular prestressed plate panels. / Localização de modos de vibração em painéis modulados de lajes protendidas.
In this research, the phenomenon of vibration modes localization in nearly periodic modular structures of linear and nonlinear behavior is studied. Of special interest is an application in Civil Engineering, lightly coupled periodic plate panels with small imperfections, mainly submitted to the variation of membrane forces introduced by prestress forces, whi

19. Pobreza, desigualdade e crescimento econômico: três ensaios em modelos de painel dinâmico / Poverty; inequality and economic growth: essays in there models of dynamic panel
This thesis is composed of three works, and they all use dynamic panel data estimation models. The estimation models used are the Generalized Moments system, developed by Arellano-Bond (1991), Arellano-Bover (1995) and Blundell and Bond (1998). The first work is entitled The Social Security system and Rural Poverty in Brazil, and it analyzes the impact of re

20. Tangibilidade e intangibilidade na determinação do desempenho superior e persistente de firmas brasileiras
RBV advocates that resources and competencies be distributed heterogeneously among firms of a determined industry, therefore, being the main cause of the variation observed in the performance of companies. When these resources are rare, valuable or difficult to be imitated and the firm disposes of an adequate organizational structure to explore them, they ha

21. A certificação ISO 9000 e o desempenho financeiro das companhias abertas brasileiras
The evidences that the quality management practices contribute positively to the financial performance of a firm do not produce a consensus. It is important to take off the impression ISO 9000 is so popular that it could not deserve more intense and effective academic production; there are many effects promoted by the introduction of this standard at the org

22. Wave propagation techniques in estimation of mechanical properties of OSB panels / Técnicas de propagação de ondas na estimativa de propriedades mecânicas de painéis OSB
Wood based materials production has grown in the national market, as it is the current international trend. Such products have been an interesting alternative to the sawn wood. Among them, OSB (Oriented Strand Board) has been of an outstanding importance. Its potential of production in the national context is expressive when supplying civil construction, fur

23. Investigação sobre a variabilidade da resposta dinamica de paineis reforçados / Investigation on the dynamic response variability of reinforced panels
In this master s thesis work, finite element method limitations are investigated in the dynamic analysis of reinforced panels. The panel was modelled using different meshes in order to show that, depending on the element length (or the number of degree of freedom) used in the model, the model does not properly stand for the real structure. In order to assess

24. Analise de simulação de cruzamento semaforizado
Conflicts emerge from the competition between elements participating in the circulation system, when these achieve severe degree traffic accidents occur. These accidents should be analyzed trom various points view so that its comprehension may indicate corrective measures. This work aims to identify the influence of dynamic publicity panels in the perception
