Diretrizes para seleção tecnológica de vedações verticais externas de edifícios em estrutura metálica. / Guidelines for technology selection of external walls of steel structural buildings.

Carla Andrade da Silva 30 May 2016 (has links)
A publicação da Norma de Desempenho (ABNT NBR 15.575:2013) e a intensificação das discussões sobre o meio ambiente têm trazido ainda mais destaque para as demandas de desempenho, sustentabilidade e construtibilidade nos projetos de edifícios. Se a inserção dessas demandas em projeto é um desafio, sua obtenção durante a execução do edifício é ainda mais difícil, sobretudo ao se considerar o processo tradicional que ainda domina a produção. Por outro lado, a industrialização do processo construtivo, facilitada pela utilização de tecnologias pré-fabricadas, tem potencial de atender às exigências de desempenho, sustentabilidade e construtibilidade. O arquiteto, enquanto profissional atuante desde o início do processo de projeto, é protagonista da seleção tecnológica, com capacidade de influenciar na adoção de um processo produtivo mais industrializado. Para discutir como o arquiteto pode melhorar sua postura frente às demandas de desempenho, sustentabilidade e construtibilidade, ocupando seu papel de agente integrador no processo de projeto, este trabalho aborda as tecnologias construtivas pré-fabricadas para vedações verticais externas (VVE) de edifícios em estrutura metálica. O objetivo principal deste trabalho é propor diretrizes para seleção tecnológica de VVE de edifícios em estrutura metálica, para o desenvolvimento do projeto de arquitetura, considerando os objetivos do empreendimento e as exigências relacionadas a desempenho, sustentabilidade e construtibilidade. A realização deste trabalho adota duas estratégias de pesquisa: revisão bibliográfica e entrevistas com projetistas de arquitetura e incorporador, com experiência na adoção de estrutura metálica e tecnologias pré-fabricadas de VVE em seus projetos. Como resultado, são propostas: diretrizes voltadas para o processo de projeto de arquitetura, incluindo recomendações para a organização da empresa de projeto que busca tomar decisões sobre tecnologias de VVE pautada em requisitos técnicos; diretrizes para identificar se o empreendimento está inserido em \"nichos estratégicos\" e se o \"ambiente\" para sua realização é favorável à adoção de tecnologias construtivas pré-fabricadas; e diretrizes para atendimento às exigências de desempenho, sustentabilidade, construtibilidade e legislação e normas técnicas a serem seguidas pelos projetistas de arquitetura. Conclui-se que, para responder às demandas de desempenho, sustentabilidade e construtibilidade, buscando adotar tecnologias construtivas pré-fabricadas de VVE, são necessários ao projetista de arquitetura: participação, de fato, na etapa de execução do edifício; estabelecimento de parcerias com agentes envolvidos no processo do empreendimento; manter-se atualizado quanto à legislação e normas técnicas (que têm revelado a tendência de não restringir ao uso de tecnologias construtivas tradicionais); especificar por desempenho as tecnologias de VVE adotadas em projeto; acompanhar a evolução das informações sobre o impacto ambiental gerado pelas tecnologias de VVE; e adotar os princípios de Coordenação Modular nos projetos. / The publication of NBR 15575: 2013 and the growing discussion about environment have brought even more emphasis on some specific demands, such as performance, sustainability and constructability in building projects. Considering that including these demands on design is a challenge, during the building construction is even more difficult, especially regarding the traditional process, which still dominates the production. On the other hand, the industrialization of construction, facilitated by usage of prefabricated technology, has potential to meet performance, sustainability and constructability requirements. The architect, an active professional since the beginning of design process, is the protagonist of technology selection and able to influence the choice for a more industrialized construction process. In order to discuss how an architect could improve his job when it comes to performance, sustainability and constructability demands, assuming an integrating agent role on design process, this research approaches the prefabricated technologies for external walls of steel structural buildings. The main purpose of the research is to propose guidelines for technology selection of external walls of steel structural buildings, aiming the architectural design development, considering the project goals and requirements related to performance, sustainability and constructability. Therefore, two research strategies have been chosen: literature review and interviews with architectural designers and developer, experienced in adopting steel structure and prefabricated technologies for external walls on their projects. As a result of this, it is proposed: guidelines oriented for the architectural design process, including recommendations to organize the design company which seeks for selecting technologies for external walls driven by technical requirements; guidelines to identify if the project is included on \"strategic segments\" and if the \"environment\" for its execution is advantageous to the adoption of prefabricated building technologies; and guidelines to meet performance, sustainability, constructability, legislation and technical standards requirements to be followed by architectural designers. In conclusion, to meet performance, sustainability and constructability demands, aiming the adoption of prefabricated building technologies for external walls, there are some specific needs for architectural designers: active participation on building execution phase; establishing partnerships with stakeholders during the development process; be up to date on the legislation and technical standards (which have been showing a trend to do not restrict the usage of traditional building technologies); to specify by performance the technologies for outside walls chosen on the project; follow the information development about environmental impact generated by outside wall technologies; and adopt the principles of Modular Coordination on the projects.

Nosná ocelová konstrukce stacionárního hydraulického agregátu / Steel structure for the the stationary hydraulic unit

Petr, Tomáš January 2017 (has links)
The main theme of this diploma thesis is a description and a strength analysis of several steel structures of valve frames used by Bosch Rexroth, s. r. o. The first part sums up possibilities of fastening of hydraulic control elements. Furthermore, current types of valve frames were described. The strength analysis of three steel structures was output of using the finite elements method. The result of these analysis was the determination of the loads and critical points of individual structures. In the end of this study, new structures for one block frame were designed to modify the critical locations of the original solution.

Drážní most nad vodotečí / Railway Bridge above the River

Hasil, Tadeáš January 2019 (has links)
The subject of this master's thesis is a static and structural design of a Load-carrying steel structure of railway bridge with bottom steel deck of the span of 42 + 60 + 42 m over the Labe river in Děčín. A solid steel beam forms the main load-bearing structure of the bridge reinforced with truss-work. The truss-work is made up of an open top chord and diagonal strut without secondary vertical struts. The calculations were done in compliance with valid ČSN EN documents.

Vícelodní průmyslová hala / Multibay industrial hall

Hrabovská, Kristýna January 2020 (has links)
The principal aim of this thesis is to design two possible options for the steel structure of a new multibay industrial hall located in Slavkov u Brna. An overhead crane with load capacity of 12.5 metric tons will by situated in one of the bays. The hall has a rectangular shape with dimensions of 63x48 meters, each of the two bays has dimensions of 63x24 meters, a height of 11.5 meters and a saddle roof with an angle of slope 10°. Both of the options have the same layout design, the only difference is that option 1 has columns with truss girders while option 2 has a transversal frame with a haunch. The first option was selected because it is more economical due to material savings and is design developed in a greater detail. The permanent load on the building is considered and includes the weight of the steel structure, panels and the weight of crane runway. The variable load is also considered due to the live load, snow load, wind load, the crane, and their combination. Steel S235 is used as the construction material.
