Com o desenvolvimento econômico e a produção no ramo metal-mecânico em ascensão, as reservas de materiais ferrosos no cenário mundial vem diminuindo cada vez mais. Visando esse aspecto, em busca de novas alternativas, o bambu pode substituir as tecnologias convencionais, como materiais ferrosos, por agregar diversas vantagens como o baixo custo, vasta disponibilidade encontrado no Brasil, alta resistência a tração, boa resistência à compressão, leveza, entre outros motivos. Para poder introduzir o bambu nos projetos estruturais é preciso conhecer as suas propriedades mecânicas, possibilitando dimensioná-los. Com isso, esse trabalho tem como propósito modelar as treliças que compõem as sustentações das coberturas dos pavimentos para circulação de pessoas presentes da UTFPR de Pato Branco e, assim, analisar o comportamento mecânico dos elementos constituídos por bambus que compõem a estrutura. Conhecendo a resistência mecânica dos bambus, com o desenvolvimento de um modelo aplicando o método dos
Greenhouses used for agricultural production are structures to partially control soil and climate conditions such as temperature, air humidity, radiation, wind, and atmospheric composition. Thus, according to Cermeño (1990) protected cultivation has quantitative and qualitative advantages compared to field cultivation since productivity in the first system can be 2 to 3 times higher. Bamboo is considered a sustainable material because it is renewable, absorbs carbon dioxide, uses solar energy, and is easily incorporated into nature at your life cycle end. The aim of this paper was to analyze the technical feasibility of bamboo in the construction of a greenhouse for protected cultivation. For this, the aerodynamic and structural behavior was analyzed in order to obtain the safety margins for this construction. With the safety margins it was determined that bamboo is a plausible material for the construction of these structures.

Con el desarrollo económico y la producción en el sector metalmecánico en aumento, las reservas de materiales ferrosos en el escenario mundial han ido disminuyendo cada vez más. Apuntando a este aspecto, en busca de nuevas alternativas, bambu puede reemplazar materiales convencionales, como materiales ferrosos, agregando varias ventajas como bajo costo, amplia disponibilidad encontrada en Brasil, alta resistencia a la tracción, buena resistencia a la compresión, ligereza, además de ser un material ecológico. Para introducir el bambú en proyectos estructurales, es necesario conocer sus propiedades mecánicas, lo que permite dimensionarlas. Yeste trabajo tiene como propósito el modelado de cerchas que componen los soportes de los techos para la circulación de personas en la UTFPR de Pato Branco y el análisis del comportamiento mecánico de los elementos constituidos por bambúes que componen la estructura. Conociendo la resistencia mecánica de los bambúes, con el desarrollo de un modelo aplicando el método del nudo, se adoptarán criterios de resistencia para estipular las tensiones permisibles de cada elemento que consiste en bambú y realizar el diseño de esta estructura.
