1. Optimal design of beam-column connections of plane steel frames using the component method
Abstract This paper presents a methodology for optimization of beam-column connections of plane steel frames. The objective is to obtain beam- column connections mechanically more efficient and with minimum cost by determination of the optimal dimensions for the components of the connection; satisfying mechanical constraints associated with the bending momen

2. Numerical analysis of truss systems with stiffened flattened end-bars
Abstract Circular hollow sections are usually used in long-span roof truss systems. One of the typology for connecting elements in such structures involves the flattening of bar ends. This article presents the numerical analysis of a plane truss composed of circular hollow sections, in which diagonal bars have flattened ends. In this sense, a new flattening

3. Excavation analysis of tunnels with lining using the boundary element method / Análise de escavações de túneis com revestimento utilizando o método dos elementos de contorno
In this work, an isoparametric boundary element method (BEM) formulation with approximation of any order was developed to the analysis of stiffened two-based on local stiffness corrections, which are made using an additional integral written in terms of initial stresses, applied over the areas close to stiffeners. Besides the usual displacement integral equa

4. Structural analysis of bending stiffeners with complex geometries utilized in offshore operations. / Análise estrutural de enrijecedores à flexão de geometria complexa utilizados em operações offshore.
The bending stiffeners discussed in this work are ancillary structural components installed on flexible lines at their connections with floating units in offshore oil production systems. The configuration of these accessories must provide the installation with a gradual variation of the bending stiffness near the lines attaching point, smoothing the curvatur
