1. Influence of growth ring orientation of some wood species to obtain toughness
Wood toughness is a mechanical property of interest in structural design where the load impact must be considered, finding a strong application in bridges, however, not an integral part of the mechanical properties commonly investigated in the characterization of this material. This study aimed to investigate with the aid of variance analysis, the influence

2. Modular bridge timber trusses system: a good alternative to the Para State / Sistemas de treliças modulares para pontes de madeira: uma boa alternativa para o Estado do Pará
The Para state has an area of 1.253.164,49 KM POT.2; it has an abundant hydrography and nearly 19.253,35 Km of vicinal roads, that are cut by many rivers. In this context, the construction of bridges with small and medium spans is essential to the improvement of intercity and interstate transportation. The system of modular timber truss bridges, was already

3. Recomendações para o projeto e construção de estruturas com peças roliças de madeira de reflorestamento / Recommendations for design and construction of structures with roundwood from tree farms
The object of this work is to propose the draft for a handbook with recommendations for the design and construction of structures using treated roundwood originating from forest farming in Brazil. Roundwood structures were classified and characterized visually and mechanically. Guidelines were presented for the desing of bridges and barns with structural and

4. Confiabilidade estrutural de pontes laminadas protendidas de madeira / Structural reliability of stress laminated timber bridges
O conceito de tabuleiros laminados de madeira protendidos transversalmente foi usado inicialmente no Canadá na década de 70. Desde então, foi largamente utilizado em um número crescente de países. No Brasil, esse sistema foi utilizado pela primeira vez com a construção da ponte sobre o rio Monjolinho, na região metropolitana de São Carlos, estado de

5. Estudo de estacas de madeira para fundações de pontes de madeira / Study of timber piles for wooden bridges foundations
This work presents a theoretical and experimental study of timber piles, including the instrumentation of the timber piles of a wooden bridge foundation, in order to generate recommendations for the project of this type of foundations for small wooden bridges. The experimental work was made in two stages. In the first stage the mechanical properties of timbe

6. Studies and applications of glued-in steel rods on shear connectors in mixed wood-concrete deck bridges / Estudos e aplicações de barras de aço coladas, como conectores em lajes mistas de madeira e concreto para tabuleiros de pontes
As pontes tradicionais de madeira no Brasil, nem sempre atingem as condições plenamente satisfatórias em estradas vicinais, exigem manutenção contínua e a maioria não está adequada ao tráfego pesado usual. As pontes mistas de madeira e concreto destacam-se como alternativa econômica apresenta grande resistência e rigidez além de exigir baixa manu

7. Orthotropic stress-laminated truss plate for timber bridges construction / Tabuleiro ortótropo treliçado protendido transversalmente para aplicação em pontes de madeira
This work aim to the theoretical and experimental study of the behaviour of orthotropic stress-laminated truss plate for timber bridges construction. To this purpose the material properties, structural elements, conections and prestress level were analysed. Two numeric models were used in order to avaliate the plate elastic properties, based on the finite el
