1. Hygrothermoelastic Analysis of Orthotropic Cylindrical Shells
Abstract In this work, the combined effect of moisture and temperature on the bending behavior of simply supported orthotropic cylindrical shells has been investigated. Initially three dimensional equilibrium equations of thermoelasticity, simplified to the case of generalized plane strain deformations in the axial direction are solved analytically for an or

2. Nonlinear Equilibrium and Stability Analysis of Axially Loaded Piles Under Bilateral Contact Constraints
AbstractThis paper presents a nonlinear stability analysis of piles under bilateral contact constraints imposed by a geological medium (soil or rock). To solve this contact problem, the paper proposes a general numerical methodology, based on the finite element method (FEM). In this context, a geometrically nonlinear beam-column element is used to model the

3. Mechanical behavior of the shear-patch loading interaction on transversally stiffened steel plate girders
In this paper, the behavior of the intertwined shear and patch loading mechanisms in transversally stiffened steel plate girders is described. The phenomenological insight depicted in this paper shows the influence of the web thickness and the flange yield strength as well as the influence of the transverse stiffeners on the stress distribution, the critical

4. Flexural analysis of cross-ply laminated beams using layerwise trigonometric shear deformation theory
In the present work, a layerwise trigonometric shear deformation theory is used for the analysis of two layered (90/0) cross ply laminated simply supported and fixed beams subjected to sinusoidal load. The displacement field of the present theory consists of trigonometric sine function in terms of thickness coordinate to take into account the effect of trans

5. Impactos potenciais do Protocolo de Cartagena sobre biossegurança nas exportações brasileiras de soja
O objetivo deste trabalho é verificar os impactos do Protocolo de Cartagena sobre Biossegurança (PCB) para o Brasil no mercado internacional, dado que o País foi o único grande exportador de commodities agrícolas que o ratificou. A análise centrou-se nas discussões do Artigo 18 e no mercado de soja. Calcularam-se os custos adicionais de identificaçã

6. Economic impacts of the introduction of the Bt11 corn in Brazil: a general equilibrium inter-regional / Impactos econômicos da introdução do milho Bt11 no Brasil: uma abordagem de equilíbrio geral inter-regional
Due to the importance of the productive chain of corn to the economy of different regions of Brazil and the liberalization of genetically modified (GM) corn cultivation in the country in 2007, this study aims to analyze the long-run economic impacts of the adoption of Bt11 corn in the inter-related sectors of the productive corn chain. Moreover, it is intend

7. Análises tensão-deformação de estruturas de solo grampeado. / Stress-Strain analysis of soil nailed structures.
The limit equilibrium methods that are frequently used for design of soi nailing structures do not provide information about the structures stress and strain. However, the techniques success depends on the displacements that mobilize the nails strength. Therefore it is desirable to predict the structures displacement, during and after the excavation; the for

8. Regras, normas e padrões no comércio internacional: o Protocolo de Cartagena sobre Biossegurança e seus efeitos potenciais para o Brasil / Rules, Norms and Standards in the international market: the Cartagena Protocol on Biosafety and its potential effects for Brazil
O estabelecimento de regras, normas e padrões internacionais relacionados ao comércio de produtos geneticamente modificados é bastante complexo e envolve uma diversidade de interesses. Essa complexidade pode ser evidenciada pela demora em se definir a forma de operacionalizar o Protocolo de Cartagena sobre Biossegurança - PCB. O PCB estabelece normas e p

9. ESTABILIDADE E DEFORMAÇÃO DE TALUDES DE SOLO SOB CARREGAMENTO SÍSMICO / STABILITY AND DEFORMATION OF SOIL SLOPES UNDER SEISMIC LOAD
The seismic stability of slopes has been a topic of considerable interest in geotechnical engineering for the past 40 years. During that period, the state of practice has moved from simples techniques to more complicated numerical procedures. The simplest approach is the pseudo-static analysis in which the earthquake load is simulated by an equivalent static

10. Numerical simulation of the wind action on a long-span bridge deck
A numerical model to study the aerodynamic and aeroelastic bridge deck behavior is presented in this paper. The flow around a rigid fixed bridge cross-section, as well as the flow around the same cross-section with torsional motion, are investigated to obtain the aerodynamic coefficients, the Strouhal number and to determine the critical wind speed originati

11. Analise de problemas de trincas interfaciais usando o metodo dos elementos de contorno
This thesis presents a procedure for computation of stress intensity factors due to the presence of interfacial cracks in bimaterial components. The procedure makes use of boundary elements method based on the formulation for bidimensional isotropic problems ldaded either in mode I or in mixed mode. The method of subregions was used to describe each one of t

12. ANALYSIS OF THE DISPLACEMENT FIELD IN THE STABILITY OF HIGH-RISE MINING SLOPES / ANÁLISIS DEL CAMPO DE DESLOCAMIENTOS PARA ESTABILIDAD DE TALUD DE GRANDE ALTURA EN MINERACIÓN / ANÁLISE DO CAMPO DE DESLOCAMENTOS PARA ESTABILIDADE DE TALUDES DE GRANDE ALTURA EM MINERAÇÃO
The evaluation of the stability of the Robert Pit Mine (Canada) is made through the field of displacements of superficial and ground marks and possible rupture mechanisms obtained from the results of tension-deformation analysis by using the program computational FLAC (V. 3.30). Two constitutive models, the elastic perfectly plastic model and elastic-plastic
