No. of bitstreams: 1 2650.pdf: 5740203 bytes, checksum: 7179b3cceecc59296850ba33bcd2404f (MD5) Previous issue date: 2009-08-28 / This work is aimed at studying slab systems for steel structures by assessing massive conventional slab, framed slab, pre-cast slabs, compsite slab systems and other systems of steel and concrete. Characteristics as well as structural and building advantages and disadvantages of each slab system for steel structures usage are addressed. Based on a defined architecture, a structural project will be developed in which the main structure (columns and beams) is supported by steel structure, and several solutions using different slab systems will be technically presented according to the methodology for mounting them, execution, and cost comparisons. A more realistic evaluation of each slab system studied was sought by comparing them to each other in terms of structural behaviour, building techniques, and cost. / Este trabalho tem como proposta estudar os sistemas de lajes para estruturas metálicas, avaliando as lajes convencionais maciças, as lajes treliçadas e pré-moldadas, a laje mista com forma de aço e outros sistemas de laje mista de aço e concreto (pavimento misto). Apresentam-se e discutem-se características, vantagens e desvantagens estruturais e construtivas de cada sistema de laje, quando usado em estruturas metálicas. Baseado numa arquitetura definida, será desenvolvido o projeto estrutural, com a estrutura principal (pilares e vigas) em estrutura metálica e com as diversas soluções em laje, avaliando tecnicamente a metodologia de montagem e execução e comparando custos envolvidos. Busca-se uma avaliação mais realista, para cada sistema de laje estudado, comparando as lajes entre si, no que diz respeito ao comportamento estrutural, às técnicas construtivas e ao custo.
