13. Modelos numéricos de vigas mistas de aço e concreto pertencentes a sistemas de pisos mistos de pequena altura em situação de incêndio / Numerical modelling of composite slim floor beams in fire
Slim floor frames consists on structural system in which the steel beam is completely or partially inserted in a concrete slab, that is usually used in profiled steel decks systems. The main goal of the slim floor systems is to obtain a minimum height of the composite beam section and, consequently, achieve a higher height of the floor or a lower total heigh

14. Contribuição ao projeto e dimensionamento da superestrutura de pontes rodoviárias em vigas mistas de aço e concreto / Contribution to the project and design of superstructure of bridges composite beams of steel and concrete
Even the metal bridges known for overcoming large spans, designed and implemented by large offices, this paper wishes to present concepts that can be applied in practical design of Steel-Concrete composite bridges of short and medium span, because those are the most common in national highways, and there is also a lack of professionals to design them into st

15. Glulam-concrete composites: experimental investigation into the connection system
Timber-concrete composite structures work appropriately when a suitable connection system is included because the degree of interaction between the materials stiffs the structural system. Thereby, it is extremely important to improve the knowledge about their connection system. The purpose of this paper is to show the results obtained by experimental investi

18. Reliability-based evaluation of design guidelines for cold-formed steel-concrete composite beams
This paper presents an analysis of design guidelines for steel-concrete composite beams, formed by concrete-filled cold-formed steel sections. The study is based on experimental results for connector resistance (push-out) and for four full-scale beam bending tests. The accuracy of analytical design equations is evaluated by comparing their predictions with e

19. 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

20. A theoretical and experimental study of steel bars contribution of the bending capacity of the partially encased composite beams / Estudo teórico-experimental da contribuição da armadura para a capacidade resistente de vigas parcialmente revestidas
This study aims to investigate the contribution of the steel bars to the flexure capacity and to promote the composite behavior in partially encased composite beams. The study includes an experimental investigation of partially encased beams under bending in four points and a numerical simulation using the computer package DIANA® to collect data from the be

21. Análise estrutural de vigas mistas de aço e concreto em perfis formados a frio: estudo da ligação viga-pilar e da região de momento negativo / Cold-formed steel and concrete composite beams: study of beam-to-column connection and region of hogging bending
No Brasil, o emprego de estruturas de aço constituídas por perfis formados a frio tem crescido consideravelmente, em virtude da ampla disponibilidade de laminados planos no mercado (chapas finas), bem como pela busca de soluções estruturais mais competitivas. Nesse cenário, pode-se destacar as estruturas mistas de aço e concreto destinadas aos edifíci

22. Verificação à fadiga de pontes rodoviárias mistas (aço-concreto) / Fatigue analysis of composite highway bridges
Steel and composite highway bridges (steel-concrete) are currently subjected to dynamic actions, for example, variable magnitude due to vehicles traffic on the deck rough pavement. These dynamic actions can generate the fractures nucleation or even their propagation on the structure. The correct consideration of these aspects pointed out to an analysis metho

23. 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

24. AVALIAÇÃO DO COMPORTAMENTO ESTRUTURAL DE CONECTORES PERFOBOND E T-PERFOBOND PARA VIGAS MISTAS / ASSESSMENT OF PERFOBOND CONNECTOR BEHAVIOUR FOR COMPOSITE BEAMS
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 c
