1. Vigas mistas com laje de concreto e perfis laminados tipo I: análise comparativa do comportamento estrutural entre conectores / Composite beams with reinforced concrete slab and rolled I beam: comparative analysis of the structural behavior of connectors
Dentre os diversos sistemas estruturais e construtivos existentes, destacam-se os sistemas formados por elementos mistos aço-concreto, cuja combinação de perfis de aço e concreto visa aproveitar as vantagens de cada material, tanto em termos estruturais como construtivos. Um fato corriqueiro que pode ser observado na execução de obras metálicas é a s

2. Vigas mistas com laje de concreto e perfis laminados tipo I: análise comparativa do comportamento estrutural entre conectores / Composite beams with reinforced concrete slab and rolled I beam: comparative analysis of the structural behavior of connectors
Among the many structural and building systems, it could be highlighted a system that is a mix of steel-concrete that allows the application of their structural and building advantages as whole. When dealing with metal structures, it was noticed some changes regarding the standards of the involved material due to its lack of availability; such measures do no

3. Composite steel and concrete beam constituted by filled cold-formed steel section / Viga mista de aço e concreto constituída por perfil formado a frio preenchido
The composite steel and concrete beams have been largely applied in buildings and bridges constructions, having also a large amount of theoretical and experimental investigations about the use of hot-rolled and welded shapes and shear connectors that are compatible with these members, as for an example, the stud bolt and channel connectors. In the cold-forme

4. Comparative study of steel purlins in conventional beams, in planar trusses and multi-planar trusses / Estudo comparativo entre terças de aço, convencionais em vigas, em treliças planas e em treliças multiplanares
Steel roof systems are widely used in buildings that require large free internal spaces and small execution times, such as commercial and industrial warehouses and storage and distribution centers. The purlins have a considerable contribution in the roof system total weight composition. In this work was developed a study on the different types of purlins for

5. Análise teórica e experimental de conectores de cisalhamento e vigas mistas constituídas por perfis de aço formados a frio e laje de vigotas pré-moldadas / Theoretical and experimental analysis of shear connectors and composite beams constituted of cold-formed steel beams and floor system with lattice girder beams
In Brazil, the lack of hot-rolled members and high cost of welded steel beams have increased the use of composite beams made of cold-formed steel beams and floor system with lattice girder beams, whose structural behavior is not perfectly understood. Although this system is similar to the one composed of hot-rolled steel beams and concrete slabs, it is impor

6. Normative criteria of influence of the Aw / Af and slenderness of soul in the calculation of the resistance to bending of beams slim in elements of steel structures. / Critérios normativos sobre influência da relação Aw/Af e esbeltez de alma no cálculo da resitência à flexão de vigas esbeltas em elementos de estruturas de aço.
Neste trabalho é feita uma análise teórica sobre o comportamento de vigas esbeltas. Uma viga esbelta foi dimensionada com base nos critérios da norma americana Manual of Steel Construction Load and Resistance Factor Design (AISC, 1994), e depois verificada pela norma brasileira NBR 8800: Projeto e execução de estruturas de aço de edifícios (método d

7. Normative criteria of influence of the Aw / Af and slenderness of soul in the calculation of the resistance to bending of beams slim in elements of steel structures. / Critérios normativos sobre influência da relação Aw/Af e esbeltez de alma no cálculo da resitência à flexão de vigas esbeltas em elementos de estruturas de aço.
This work contains a theoretical analysis of the behavior of plate girders. A plate girder has been calculated based on the criteria of the American standard Manual of Steel Construction Load and Resistance Factor Design (AISC, 1994), and checked by the Brazilian standard NBR 8800: Projeto e execução de estruturas de aço de edifícios (método dos estados
