1. STRESS, DISPLACEMENT JOINTS OF GMELINA ARBOREA AND TECTONA GRANDIS WOOD WITH METAL PLATES, SCREWS AND NAILS FOR USE IN TIMBER TRUSS CONNECTIONS
ABSTRACT In countries like Costa Rica, there is an interest in developing wooden trusses in a versatile and light way. However, there is a key aspect in the behavior of truss connections in this product. Therefore, the present study determines the structural behavior of the truss connections and the displacement, the resistance, the stiffness values and the

2. Influence of nails size and layout to obtain the reduction coefficient of moment of inertia for timber beams with composite cross section
ABSTRACT A significant portion of rural building’s roof is supported by timber trusses. Increasing distance between the trusses can be achieved by using composite cross sections ("T" and "I") for beams. With this, it is possible to reduce the number of columns and trusses, bringing significant savings in material and the desired cost reduction, mainly usin

3. 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

4. Forces on bracing elements of timber trusses / Forças em peças de contraventamento de treliças de madeira
This work analyzes the forces acting on the bracing bars of triangular timber trusses by computational numerical models. The models are produced in the system of structural analysis Strap and consider the operation of bracing in the three-dimensional structure. The maximum forces obtained in the three-dimensional models are compared to the minimum values ind

5. Optimation and dimensional of plane trusses of Wood, applying the genetic algorithms method / OtimizaÃÃo e dimensionamento de treliÃas planas de madeira empregando o mÃtodo dos algoritmos genÃticos
The objective of this study is to present information on the optimization of plane truss wooden structure using the method of genetic algorithms. All assessments are made by the computer program called Optimization Structures Plane (OTP). It was also used the computer program GESTRUT for determining forces and displacement. It was evaluated pitched trusses,

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
