1. Composite floor system with CFS trussed beams, concrete slab and innovative shear connectors
Abstract Steel and concrete floor systems are widely applied for buildings and provide excellent structural response, optimized material consumption, reduced beam height, and improved bending strength and stiffness capacity. In recent years, many experimental investigations concerned with new alternatives addressed to efficient interaction between steel and

2. Free Vibration of flexible soft-core sandwiches according to layerwise theories differently accounting for the transverse normal deformability
Abstract This study aims to generalize a previously developed accurate and inexpensive 3-D zig-zag theory up to an arbitrary representation form and to determine which simplifications are yet accurate in determining transverse shear and normal stress/deformation effects on vibrations of soft-core sandwiches with not moving middle/neutral plane (pumping).

3. Non-Linear Three Dimensional Finite Elements for Composite Concrete Structures
Abstract The current investigation focused on the development of effective and suitable modelling of reinforced concrete component with and without strengthening. The modelling includes physical and constitutive models. New interface elements have been developed, while modified constitutive law have been applied and new computational algorithm is utilised. T

4. A Differential Quadrature Procedure with Direct Projection of the Heaviside Function for Numerical Solution of Moving Load Problem
Abstract Owing to its particular characteristics, the direct discretization of the Dirac-delta function is not feasible when point discretization methods like the differential quadrature method (DQM) are applied. A way for overcoming this difficulty is to approximate (or regularize) the Dirac-delta function with simple mathematical functions. By regularizing

5. Evaluation and comparison of behavior of corrugated steel plate shear walls
In this paper, the nonlinear behaviour of steel plate shear walls with corrugated plates under lateral pushover loading conditions in the models' top level has been analytically investigated by the finite element method. The one-storey frames have beams and columns as boundary elements. Steel plate shear walls are simulated using the finite element method, b

6. A Differential Quadrature Procedure with Regularization of the Dirac-delta Function for Numerical Solution of Moving Load Problem
AbstractThe differential quadrature method (DQM) is one of the most elegant and efficient methods for the numerical solution of partial differential equations arising in engineering and applied sciences. It is simple to use and also straightforward to implement. However, the DQM is well-known to have some difficulty when applied to partial differential equat

7. Strengthening of structurally damaged wide shallow RC beams using externally bonded CFRP plates
Reinforced concrete wide shallow beams (WSBs) are commonly used in the joist flooring systems. The structural behavior of WSBs strengthened with carbon fiber reinforced polymer (CFRP) reinforcement was studied on isolated beams and as part of full-scale building. The effect of structural damage on the performance of WSBs flexurally strengthened with CFRP pla

8. Análise da interação placa-viga via método dos elementos de contorno / Analysis of plate-beam interaction by the Boundary Element Method
This work presents a formulation of the boundary element method for the analysis of plate-beam interaction in buildings floors. In order to properly match the beams and plate is used an alternative formulation of the boundary element method for thin plates, in which the beam is modeled by ordinary differential equations and the compatibility between plate an

9. 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

10. Projeto e construção de placas espalhadoras e degradadoras de energia para uso em radioterapia com feixes de elétrons para doenças de pele / Project and construction of energy degrading and scattering plates for electron beam radiotherapy for skin diseases
There are many radiosensitive epidermotropics diseases such as mycosis fungoids and the syndrome of Sézary, coetaneous neoplasics originated from type T lymphocytes. Several studies indicate the eradication of the disease when treated with linear accelerators emitting electron beams with energies between 4 to 10 MeV. However, this treatment technique presen

11. Análise numérica da influência da excentricidade na ligação placa-viga em pavimentos usuais de edifícios / Numerical analysis of plate-beam coupling eccentricity influence of usual buildings slabs
Its usual practice on structural analysis of buildings slabs to assume the concentricity between plates and beams. Numerical studies in waffle-slabs, where the distance between beams is small, showed that the eccentricity of beam to plate results in reduction of stresses and displacements of the system, however there is not similar study about the influence

12. A new approach in the use of computational tools in teaching content of the discipline "Concrete Structures" in the Civil Engineering courses / Uma nova abordagem na utilização de ferramentas computacionais no ensino de conteúdos da disciplina estruturas de concreto em cursos de Engenharia Civil
This presentation analyzes the two computational tools, GPLAN (Plan Grills) and FTOOL (Two-Dimensional Frame Analysis Tool), and how they can be used in the content of "Concrete Structures" discipline, in Civil Engineering Graduation. The considered study is divided in two topics, being the first, the plan grills consideration (interaction plate/ beam) in th
