Modelo não linear de viga para a obtenção de esforços em serviço aplicado a lajes de barragem de enrocamento com face de concreto
No full textDissertação (mestrado) - Universidade Federal de Santa Catarina, Centro Tecnológico, Programa de Pós-Graduação em Engenharia Civil, Florianópolis, 2009Em projetos estruturais, a determinação das solicitações para a verificação dos Estados Limites de Serviço é feita usualmente, com uma análise elástico-linear. Porém, pode ser que ocorram pequenas redistribuições de esforços mesmo em condições de utilização, devido à fissuração das seções mais solicitadas, principalmente no caso de peças dimensionadas com redistribuição de esforços. Neste caso, seria recomendável uma análise não linear para a determinação dos esforços solicitantes em serviço. Contudo, estas análises são geralmente complexas, necessitando certo grau de conhecimento teórico pelo projetista e modelos que exigem tempos de processamento computacional relativamente elevados, dificultando assim o seu uso em projetos usuais. Este trabalho tem por objetivo desenvolver um procedimento simplificado para a determinação dos esforços solicitantes em elementos sob condições de serviço, onde são utilizados diagramas momento curvatura para a consideração da não-linearidade dos materiais. Foi desenvolvido um programa computacional como forma de automatizar o processo iterativo que envolvem essas análises. Foram implementados no programa três tipos de diagramas momento-curvatura para se levar em conta a contribuição do concreto entre fissuras, o primeiro deles indicado pela NBR6118 proposto por Branson, o segundo retirado do CEB-FIP Model Code e o terceiro um diagrama bilinear simplificado. Foram estudados inicialmente exemplos de vigas contínuas, averiguando se há redistribuição de esforços em serviço, comparando os resultados obtidos pelos três diferentes diagramas com os resultados usuais de uma análise elástico-linear.O mesmo procedimento, com pequenas alterações, foi utilizado para o estudo de lajes de barragens de enrocamento com face de concreto, onde exercem função de vedação. Essas lajes possuem um comportamento pouco usual, já que pouco contribuem para a resistência da estrutura, estando praticamente submetidas a deslocamentos impostos.In structural design, the verification of serviceability limit states is usually done, by means of a linear-elastic analysis. However, small redistributions may occur, even under service conditions, due to cracking in the sections subjected to highest action effects, particularly in the case of structures designed with redistribution. In this case, is recommended a nonlinear analysis to determine the solicitations in service. Nevertheless, these analyses are usually complex, requiring some theoretical knowledge by the designer and models that require high computational processing time, making it difficult for use in regular projects. This work has the purpose to develop a simplified procedure to determine member efforts under service loads, where moment curvature diagrams are used to account for material nonlinearities. A computer program was developed as a way to automate the iterative process involving the analysis. To take into account the contribution of concrete between cracks, three types of momentcurvature diagrams were implemented. The first one indicated by NBR6118, as proposed by Branson; the second one taken from the CEB-FIP Model Code; and the third one is a simplified bi-linear diagram. Examples of continuous beams were initially studied, by checking if there is bending redistribution under service, and then comparing the results obtained by using the three different diagrams with the usual results of a linear-elastic analysis. The same procedure, with minor modifications, was used to study slabs of concrete face rockfill dams, where they exert sealing function. These slabs have an unusual behavior, since they provide a little contribution to the resistance of the structure, being subjected to imposed displacements

Associations between area-level unemployment, body mass index, and risk factors for cardiovascular disease in an urban area
No full textINTRODUCTION: Il existe peu d’évidences sur l’association entre le taux de chômage dans le milieu résidentiel (CR) et le risque de maladies cardiovasculaires parmi les résidents de milieux urbains. De plus, on ne sait pas si ce lien diffère entre les deux sexes. Cette thèse a pour objectif de déterminer la direction et la taille de l’association entre le CR et le risque de maladies cardiovasculaires, et d’examiner si cette association varie en fonction du sexe. MÉTHODES: Un sous-échantillon de 342 participants de l’Étude sur les habitudes de vie et la santé dans les quartiers montréalais a rapporté ses habitudes de vie et sa situation socio-économique. Des mesures biologiques et anthropométriques ont été recueillies par une infirmière. Le CR a été opérationnalisé en fonction d’une zone-tampon d’un rayon de 250 m centrée sur la résidence de chacun des participants à l’aide d’un Système d’Information Géographique (SIG). Des équations d’estimation généralisées ont été utilisées afin d’estimer l’association entre le CR et l’Indice de Masse Corporelle (IMC) et un score cumulatif de Risque Cardio-métabolique (RC) représentant la présence de valeurs élevées de cholestérol total, de triglycérides, de lipoprotéines de haute densité et d’hémoglobine glyquée. RÉSULTATS: Après ajustement pour l’âge, le sexe, le tabagisme, les comportements de santé et le statut socio-économique, le fait de vivre dans un endroit classé dans le 3e ou 4e quartile de CR était associé avec un IMC plus élevé (beta pour Q4 = 2.1 kg/m2, IC 95%: 1.02-3.20; beta pour Q3 = 1.5 kg/m2, IC 95%: 0.55-2.47) et un taux plus élevé de risque cardiovasculaires Risque Relatif [RR pour Q4 = 1.82 (IC 95 %: 1.35-2.44); RR pour Q3 = 1.66 (IC 95%: 1.33-2.06)] par rapport au 1er quartile. L'interaction entre le sexe et le CR révèle une différence absolue d’IMC de 1.99 kg/m2 (IC 95%: 0.00-4.01) et un risque supérieur (RR=1.39; IC 95%: 1.06-1.81) chez les femmes par rapport aux hommes. CONCLUSIONS: Le taux de chômage dans le milieux résidentiel est associé à un plus grand risque de maladies cardiovasculaires, mais cette association est plus prononcée chez les femmes.INTRODUCTION: Little is known about whether area-level unemployment is independently associated with individual-level Cardiovascular Disease (CVD) in an urban setting. Furthermore, it is unclear whether this relationship differs by sex. This thesis examined the direction and magnitude of the association between area-level unemployment (ALU) and Body Mass Index (BMI) and a marker for CVD risk, and whether this association differs by sex. METHODS: A sample of 342 individuals from the Montreal Neighbourhood Survey of Lifestyle and Health (MNSLH) self-reported behavioural and socioeconomic information. A registered nurse collected biochemical and anthropometric data. ALU was operationalised within a 250 m radius buffer centered on individual residence using a Geographic Information System (GIS). Generalized Estimating Equations were used to determine if body mass index (BMI), and a cumulative score for total cardiometabolic risk (TCR) representing elevated values for total cholesterol, triglycerides, high-density lipoprotein cholesterol, and glycosylated hemoglobin, were associated with ALU. RESULTS: After adjustment for age, gender, smoking status, behavioural, and socioeconomic covariates, living in an area in the upper ALU quartiles was associated with an elevated BMI [Q4 beta = 2.1 kg/m2 (95% CI: 1.02-3.20)] and greater TCR [Q4 RR = 1.82 (95 % CI: 1.35-2.44); Q3 RR = 1.66 (95% CI: 1.33-2.06)] relative to the 1st quartile. Sex-by-ALU interaction revealed a 1.99 kg/m2 (95% CI: 0.00-4.01) difference in BMI and 1.39-fold (95% CI: 1.06-1.81) greater TCR Score for women compared to men. CONCLUSIONS: Area-level unemployment is associated with greater CVD risk in men and women but associations are stronger among women
Do Women Shy Away From Competition? Do Men Compete Too Much?
No full textCompetitive high ranking positions are largely occupied by men, and women remain scarce in engineering and sciences. Explanations for these occupational differences focus on discrimination and preferences for work hours and field of study. We examine if absent these factors gender differences in occupations may still occur. Specifically we explore whether women and men, on a leveled playing field, differ in their selection into competitive environments. Men and women in a laboratory experiment perform a real task under a non-competitive piece rate and a competitive tournament scheme. Although there are no gender differences in performance under either compensation, there is a substantial gender difference when participants subsequently choose the scheme they want to apply to their next performance. Twice as many men as women choose the tournament over the piece rate. This gender gap in tournament entry is not explained by performance either before or after the entry decision. Furthermore, while men are more optimistic about their relative performance, differences in beliefs only explain a small share of the gap in tournament entry. In a final task we assess the impact of non-tournament-specific factors, such as risk and feedback aversion, on the gender difference in compensation choice. We conclude that even controlling for these general factors, there is a large residual gender gap in tournament entry.
