As estruturas de piso misto de madeira e concreto já algum tempo fazem parte do contexto construtivo pelo mundo, sendo empregadas principalmente na recuperação de pisos antigos de madeira em residências uni ou multi familiares, principalmente em países da Europa e da America do Norte, são usadas também em estruturas de pontes e passarelas ao ar livre pois a placa de concreto protege a madeira das intempéries, radiações solares entre outros. Vários fatores contribuem a favor do uso deste tipo de estrutura em residências, entre eles destacam-se: o custo bem mais barato que a construção convencional em concreto armado, a leveza arquitetônica do arranjo, com as peças de madeira aparentes envernizadas e laje pintada, proporcionando um acabamento muito bom, o isolamento térmico e acústico se tomarmos como referencia os pisos somente de madeira. Este trabalho ressalta o uso de madeiras de reflorestamento no Brasil, sendo escolhida por sua beleza e resistência a Tectona Grandis (TECA), e para a laje que compõem a mesa escolhemos um concreto de pós-reativos, onde alguns agregados são subprodutos das indústrias de papel e vidro. A geometria traçada para laje foi delineada em busca de se ter o melhor arranjo estrutural, aliado ao bom efeito arquitetônico. As expressões para cálculo do piso misto madeira-concreto estão fundamentadas nas equações de equilíbrio e nos preceitos da EUROCODE 5 os parâmetros para verificação e segurança seguem os preceitos da NBR 7190/97, NBR 6118/14 da própria EUROCODE 5. Os resultados apresentados demonstram que há diferenças entre os métodos de cálculo analítico e de elementos finitos (SAP 2000), os resultados entre estes modelos tiveram diferenças quanto ao modelo experimental, às medições realizadas mostraram uma rigidez efetiva bem mais elevada que as apresentadas nos dois modelos citados anteriormente. Concluímos então, que os módulos de elasticidade dos materiais e o módulo de deslizamento devem ser ensaiados para que haja uma proximidade com resultados experimentais. Os resultados obtidos no modelo experimental nos mostra ótima rigidez, os fatores de segurança quanto aos EL Último e de utilização, foram atendidos o custo final da montagem mesmo com a utilização do concreto de pós-reativos ficou mais baixo que o custo de uma estrutura convencional, assim podemos denotar que as estruturas de concreto-madeira apresentam ótimas condições de emprego em construções e reformas, sendo de suma importância o incentivo e a continuidade dessa técnica construtiva. 2018-05-21T19:10:57Z 2018-05-21T19:10:57Z 2016-12-20 Dissertação BRITTO, Raimundo Angelo de Lima.
