1. Numerical analysis of collapse modes in optimized design of alveolar Steel-concrete composite beams via genetic algorithms
Abstract The objective of this study is to present the formulation and applications of the optimization problem of steel-concrete composite alveolar beams. In addition to presenting the formulation, a comparative analysis of the predominant collapse modes is performed numerically via the finite element method. The optimization program was developed with the

4. Some Aspects of Numerical Modeling of Steel-Concrete Composite Beams with Prestressed Tendons
Abstract Aspects about the numerical modeling of three-dimensional prestressed steel-concrete composite beams by using the finite element (FE) method are highlighted and commented in this work. Emphasis is given to the numerical treatment of bonded and unbonded tendons. The proposed modeling technique uses curved beam and catenary elements for simulating int

6. Parametric Modal Dynamic Analysis of Steel-Concrete Composite Beams with Deformable Shear Connection
Abstract Composite structural elements of steel-concrete began to be used only in 1960 after the development of methods and constructive dispositions that ensured the functionality of these two materials together. In order to verify the importance of the participation of the axial mode in the frequency spectrum of the free vibration problem in composite beam

9. 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

10. 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

12. 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
