Testo completoEsta dissertação trata da modelagem dos esforços transmitidos por atuadores piezoelétricos, colados ou embutidos em vigas compósitas laminadas. O trabalho é motivado por aplicações na área de materiais e estruturas inteligentes. Em particular, procura-se avaliar o comportamento de diferentes teorias aproximadas nas faixas de médias e altas frequências, quando os comprimentos de onda podem ser da ordem da espessura da viga. Nestes casos, teorias tradicionais de vigas deixam de representar com acuracidade a resposta dinâmica de estruturas compósitas. Além disso, modelos convencionais que procuram representar os esforços gerados pelo atuador por forças e momentos fletores equivalentes, geralmente resultantes de uma análise estática, deixam de ser efetivos. São estudados modelos baseados na Teoria Clássica de Laminação (hipótese cinemática de Bernoulli-Euler) e na Teoria de Deformação Cisalhante de Primeira Ordem (hipótese cinemática de Timonshenko) e na Teoria discreta de Laminação proposta por Reddy (Reddy’s Layerwise Theory). Os três modelos são escritos na forma de equações de estado, e um método de solução é proposto para se obter a matriz de impedância dos atuadores. Resultados dos modelos estudados são comparados com os obtidos pelo método dos elementos finitos (código ANSYStm). São apresentados resultados para atuadores formados por camadas de PZT e Alumínio, bem como por camadas intercaladas de PZT, Aramide-Epóxi e Alumínio.
This dissertation addresses the problem of modeling the excitation of laminated composite beams by piezoelectric patches bonded or embedded in the structure. This work has been motivated by applications in the field of smart structures and materials. In particular, attention is paid to the electromechanical response in the high-frequency range. An attempt is made to evaluate the capabilities of different laminate theories in the medium and high-frequency ranges, where traditional models, such as the Classical (Bernouli-Euler) or First Order Shear Deformation (Timoshenko) theories, fail to provide accurate assessments of the structural dynamic response. Also, at these frequency ranges, conventional approaches to model the piezoelectric excitation via equivalent forces and bending moments, usually resulting from static analysis, are no longer satisfactory. Three different laminate theories are investigated: Classical, First Order Shear Deformation, and Reddy’s Layerwise theories. In the frequency domain, the governing electro-elastodynamic equations are written in a common state space formulation. A general method of solution is presented where the impedance matrix for the actuator is analytically evaluated. Comparisons are also made with numerical models obtained from a commercial finite element code.

Testo completoOn the basis of the slab behaviour identified, truss idealizations capable of determining the slab shear carrying capacity in a rational manner were developed. Then, the ultimate strength for composite beams at web holes was formulated including the truss idealizations. Another ultimate strength analysis accounting for the slab shear carrying capacity in a simple manner, which was also developed during this research project, is given. This provided the fundamental solution procedure for the plastic analysis used.
A series of nine tests was carried out with particular attention being directed to the verification of the proposed truss analogy. The major test parameters included the configurations of the studs in the hole region, the width of the concrete slab and stud detailing near the high moment end of the hole. The ultimate strength predictions were made by the two methods developed, and compared with previous and present test results.

As vigas mistas são um exemplo das cada vez mais difundidas estruturas mistas, e resultam da associação de uma viga de aço com uma laje de concreto ou mista, ligadas por meio dos conectores de cisalhamento. Dentre os diversos tipos existentes pode-se citar os pernos com cabeça (stud bolts), perfis C e o Perfobond. Um conector alternativo foi proposto para estruturas mistas, o TPerfobond, que deriva do conector Perfobond acrescentando a componente da mesa, que trabalha como um bloco. Combina portanto a alta resistência do conector tipo bloco com a ductilidade e resistência ao levantamento dos furos do Perfobond. Para determinação da sua capacidade resistente foi realizado um programa experimental envolvendo cinquenta e dois ensaios do tipo push-out com conectores Perfobond, T-Perfobond e T, um ensaio em escala real e uma modelagem numérica. Os ensaios push-out estabeleceram a carga máxima e a capacidade de deformação dos conectores. Procurou-se com o ensaio em escala real determinar a resistência última da estrutura, o modo de ruína, as deflexões e as deformações, e validar o comportamento do conector TPerfobond em uma estrutura real. Os resultados indicaram que o modelo de plastificação total pode ser adotado para a determinação do momento fletor resistente em vigas mistas bi-apoiadas com conectores T-Perfobond. Os modelos numéricos auxiliaram no estudo da capacidade de deformação da mesa do conector T-Perfobond, e na investigação das vigas com interação total ou parcial ao cisalhamento. Sob o ponto de vista econômico, um estudo comparativo dos custos dos conectores Perfobond, T-Perfobond e Studs foi conduzido e concluiu-se que os conectores Perfobond e T-Perfobond são mais econômicos em até 33% que os conectores Studs. Dentre as vantagens estruturais e construtivas de utilizar os tipos de conectores alternativos destacam-se: a alta resistência, a fácil produção e instalação no perfil de aço através de solda corrente, e bom comportamento à fadiga.
Steel and composite beams have been extensively used in buildings and bridges. The component that assures the shear transfer between the steel profile and the concrete deck, enabling the composite action to develop, is the shear connector. Among the different types of connectors the headed studs, C sections and the Perfobond may be referred. An alternative connector has been proposed for composite structures, the T-Perfobond. The main difference between the studied Perfobond and T-Perfobond connectors is the presence of a flange, providing a further anchorage to the system. This connector combines the high strength of the block connector with ductility and resistance to uplift of the Perfobond holes. To evaluate their shear capacity an experimental programme that consisted of fifty-two push-out test and one full-size test, and some numerical analysis were performed. The push-out tests have established the maximum load capacity and deformation of the connectors. The full-size test has determined the composite beam load carrying capacity, typical failure modes, associated stresses and displacements, and has validated the behaviour of the T- Perfobond connector in an actual structure. The results indicated that the plastic distribution can be adopted for T- Perfobond connectors. The numerical analysis helped in the assessment of the deformation capacity of the T-Perfobond flange connector, and the investigation of the composite beam with total or partial connection. From the economic point of view, a comparative study of the cost of Perfobond, TPerfobond and Studs connectors was conducted and it was concluded that the Perfobond and T-Perfobond connectors lead to an economy of up to 33% when comparing to the Studs connectors. Among the structural and constructive advantages of the use of alternative types of connectors, an high resistance, easy manufacturing and installation of steel beam by current welding and good performance to fatigue may be referred.

Testo completoThe vibration characteristics of castellated beams were examined using experimental and analytical test methods. The effective moment of inertia is essential to accurately predict the frequency and deflection of a floor system due to human occupancy. Since castellated beams have non-prismatic cross-sections, their effective moment of inertia is an uncertainty and was verified in this study. This paper confirmed the accuracy of the AISC Design Guide procedures used in for prismatic beam, when applied to castellated beams.
The flexural strength of various composite castellated beam were studied. Three full-scale specimens were tested to failure to evaluate their yield and maximum applied load. Each specimensâ moment strength was verified based on span, beam properties, concrete slab, and amount of shear connection.
