The wood for the civil engineering: A proposal of distance education

The majority of the Brazilian schools of Civil Engineering have taught the subject works with wood in the traditional only by disciplines of Metallic Structures and Wood at a topic in the content of the program on disciplines at the Materials of Civil Construction. To extend of the wood studies is being made possible that all the pupils have a wider understanding of this material and its adapted use is the goal of the proposal, that by the means of the education modality e-learning, disclosing the first one: Module I - Introduction to the Study of the Wood. This methodology tries to use the theoretical beddings in projects that are related to the pupil daily tasks and its practical professional. The article presents the theoretical bases of the conception proposal and its structure, and at the conclusions, the problems found during its application are displayed. Basically, the methodology considers that the professor and the pupil must share the learning, and adopt it as main in the interdisciplinary.

The formation of the professionals for the timber industrial sector of the civil construction

The common point between the two forms of production of the wood-based sector in Brazil, one practically manufacturing and the other high technology, is in the qualification of the of the labor. In both cases, the professionals are being formed directly in the productive line and rarely with qualification in the academic area. There is not a public political education for the qualification of the labor, and the work market that does not demand qualified professionals, contributes for the sector stagnation. So, in order to excel the socio-cultural barriers in relation to the use of wood in the buildings, new attitudes are necessary in the teaching of the contents of the curricular programs, mainly, in formation of the architect and civil engineering.

Jogo de empresas para administração e controle de custos: um modelo para empresas fornecedoras de componentes para a construção civil

Este trabalho apresenta um modelo de jogo de empresas visando atender a gestores de empresas fornecedoras de componentes para a construção civil, caracterizadas pela onisciência dos mesmos, com dificuldades em compreender e utilizar as informações econômico-financeiras presentes nos relatórios, bem como promover o estreitamento teórico e prático dessas informações à comunidade acadêmica de Engenharia. Para o desenvolvimento do jogo de empresas fez-se necessário, além do reconhecimento de algumas empresas fornecedoras de componentes para a construção civil, um estudo de conceitos e técnicas contábeis, no que tange à Contabilidade de Custos e Gerencial. O jogo foi aplicado no ambiente acadêmico da Universidade Federal do Pará, junto a alunos de Engenharia Civil, que para tanto, tiveram que passar por um processo de nivelamento conceitual e de conhecimento da dinâmica do jogo, e em uma microempresa, Proativa, na cidade de Belém. Os resultados confirmaram as vantagens do uso da simulação empresarial abordada neste trabalho no processo ensino-aprendizagem.

Análise de inconformidades em obras recentes

Due to the large number of pathologies in the civil constructions justified to highlight the reasons for problems encountered and subsequently the most appropriate way of implementing procedures for certain services performed in civil construction. The intention here is to explain each of the subjects studied, identify and distinguish the conditions presented in the post delivery of civil constructions from construction X, through research and company documents, and highlight steps of the executives of some services civilians highlighted in this work to minimize, or cancel, future maintenance. Studies will be conducted in a more narrow, focused more specifically in the most happening pathologies in the constructions and how to perform each service to prevent future problems with masonry (non-structural cracks and crevices), waterproofing, window frames and cladding. Thus, this study seeks to protect the building, using material technology and equipment, to allow an increase in the service time of the building,

Análise geoambietal para o planejamento de obras civis lineares: uma abordagem por sensoriamento remoto orbital

Construction of linear engineering as, roads, ducts and multiducts as roads, has a strong feature of the diversity of land on which they are deployed. This diversity involves properties geological, geomorphological and structural variety. The purpose of this work is to characterize the physical environment in relation to their ability to support the implementation of civil works linear. To achieve this, the use of orbital remote sensing, in this case, Landsat - TM. Interpretative techniques are applied to images in order to assess the forms of relief and drainage found that they can set properties and have built a favorable meaning or not to implement these works. The results and thematic maps presented in this study allow us to promote the geoenvironmental analysis for the planning phase sustainable linear civil constructions (roads and multiducts)

Galloping instabilities of Z-shaped shading louvers

Modern design of civil constructions such as office blocks, airport terminal buildings, factories, etc. incorporates more and more environmental considerations that lead to, amongst other elements, the use of glazed façades with shading devices to optimize energy consumption. These shading devices, normally slats or louvers, are very flexible structures exposed to the action of wind, and therefore aeroelastic effects such as galloping must be taken into account in their design. A typical cross-section for such elements is a Z-shaped profile made out of a central web and two side wings. The results of a parametric analysis based on static wind tunnel tests and performed on different Z-shaped louvers to determine translational galloping instability regions are presented in this paper.

Investigación de fenómenos de galope en cuerpos de diversa sección transversal

Los fenómenos aeroelásticos son relativamente frecuentes en las construcciones civiles modernas como edificios de oficinas, terminales de aeropuertos o fábricas. En este tipo de arquitectura aparecen con frecuencia estructuras flexibles sometidas a la acción del viento, como por ejemplo persianas formadas por láminas con distintos perfiles. Uno de estos perfiles es el perfil en Z, formado por un elemento central y dos alas laterales. Las inestabilidades de tipo galope se determinan en la práctica utilizando el criterio Glauert-Den Hartog. Este criterio precisa de la predicción exacta de la dependencia de los coeficientes aerodinámicos del ángulo de ataque. En esta tesis se presenta un estudio sistemático, tanto por métodos experimentales como numéricos de una familia completa de perfiles en Z que permite determinar sus regiones de inestabilidad frente al galope. Los análisis numéricos han sido validados con ensayos estáticos realizados en túnel de viento. Para la parte numérica se ha utilizado el código DLR TAU, que es un código de amplia utilización en la industria aeronáutica europea. En esta tesis se enfoca sobre todo a la predicción del galope en este tipo de perfiles en Z. Los resultados se presentan en forma de mapas de estabilidad. A lo largo del trabajo se realizan también comparaciones entre resultados numéricos y experimentales para varios niveles de detalle de las mallas empleadas y diversos modelos de turbulencia. ABSTRACT Aeroelastic effects are relatively common in the design of modern civil constructions such as office blocks, airport terminal buildings, and factories. Typical flexible structures exposed to the action of wind are shading devices, normally slats or louvers. A typical cross-section for such elements is a Z-shaped profile,made out of a central web and two-sidewings. Galloping instabilities are often determined in practice using the Glauert-DenHartog criterion.This criterion relies on accurate predictions of the dependence of the aerodynamic force coefficients with the angle of attack. The results of a parametric analysis based on both experimental and numerical analysis and performed on different Z-shaped louvers to determine translational galloping instability regions are presented in this thesis. These numerical analysis results have been validated with a parametric analysis of Z-shaped profiles based on static wind tunnel tests. In order to perform this validation, the DLR TAU Code, which is a standard code within the European aeronautical industry, has been used. This study highlights the focus on the numerical prediction of the effect of galloping, which is shown in a visible way, through stability maps. Comparisons between numerical and experimental data are presented with respect to various meshes and turbulence models.

Animal Lovers, Bridge-Builders, and Supervising Watchdogs: Framing and Civil Society Construction by Japanese Pro-Animal Organizations in the Kansai and Tokyo Areas

Unlike their counterparts in Europe and America, the citizen organizations acting for the well-being of animals in Japan have not received scholarly attention. In this research, I explore the activities of twelve Japanese pro-animal organizations in Tokyo and Kansai area from the perspective of social movement and civil society studies. The concept of a ‘pro-animal organization’ is used to refer generally to the collectives promoting animal well-being. By using the collective action frame analysis and the three core framing tasks – diagnostic, prognostic, and motivational – as the primarily analytical tools, I explore the grievances, tactics, motivational means, constructions of agency and identity as well as framing of civil society articulated in the newsletters and the interviews of the twelve organizations I interviewed in Japan in 2010. As the frame construction is always done in relation to the social and political context, I study how the organizations construct their roles as civil society actors in relation to other actors, such as the state, and the idea of citizen activism. The deficiencies in the animal welfare law and lack of knowledge among the public are identified as the main grievances. The primary tactic to overcome these problems was to educate and inform the citizens and authorities, because most organizations lack the channels to influence politically. The audiences were mostly portrayed as either ignorant bystanders or potential adherents. In order to motivate people to join their cause and to enforce the motivation within the organization, the organizations emphasized their uniqueness, proved their efficiency, claimed credit and celebrated even small improvements. The organizations tended to create three different roles for citizen pro-organizations in civil society: reactive, apolitical and emphatic animal lovers concentrating on saving individual animals, proactive, educative bridge-builders seeking to establish equal collaborative relations with authorities, and corrective, supervising watchdogs demanding change in delinquencies offending animal rights. Based on the results of this research, I suggest that by studying how and why the different relations between civil society and the governing actors of the state are constructed, a more versatile approach to citizens’ activism in its context can be achieved.

A utilização da Manihot esculent crantz (mandioca) na indústria de chapas de compensados de madeira e seu impacto econômico e social na construção civil

Esta pesquisa tem como objetivo determinar as vantagens socioeconômicas para produção de chapas de compensados de madeira na construção civil substituindo a farinha de trigo por farinha de raspa de mandioca na formulação da cola de compensado de madeira. Abordou-se acerca da estrutura anatômica da madeira e suas propriedades, os tratamentos e processos industriais, a estrutura e o processo de produção de compensado além da substituição do insumo na formulação da cola de uréia-formoaldeído desenvolvendo-se então uma avaliação econômica de benefício-custo do compensado de madeira utilizado em fundação e estrutura em uma obra de edificação através da análise de preços dos insumos da cola de mandioca em substituição a cola de trigo. A análise mostra que em nível de composição de insumo principal de produção houve uma redução de 7,3% no custo da cola. Para a construção civil a chapa de compensado de madeira com adesivo de mandioca utilizada em fundação e estrutura não representa um percentual significativo de redução de custos, sendo o percentual do custo do compensado de madeira em uma obra padrão é de apenas 0,84% para economia. Em nível social o governo criou o Programa Nacional para o Fortalecimento da Agricultura Familiar para apoiar o desenvolvimento das indústrias de base da economia como a indústria da construção civil.

Proposta de estruturação do departamento de custos de uma empresa de construção civil de médio porte

This work consists of a literature review of technical project management with a focus on cost management in order to establish concepts and build a theoretical basis for later perform a case study of a construction company. All of the literature review is based on best practices in project management from the Project Management Institute - PMI, among other bibliographies that use the same concepts. The case study covers issues such as area of expertise, constructions undertaken, methodologies, procedures, assumptions, allowing to understand how the company operates in the market and, especially, which interfaces with the cost department in company processes. Confronting the knowledge gained from the literature review of the concepts of PMI and the information obtained from the case study on the current situation of the management costs of the company, it was possible to identify some gaps in the company processes of cost management and thus propose the solution of creating a centralized functional area focused on cost, that is responsible for ensuring that best practices in project management, specifically costs, are being applied
