Resumo: | This work is focused on lightweight wood-frame constructions, which are accepted worldwide and may be considered feasible for use in Brazil as well. It presents the results of experimental tests on floor diaphragms subjected to lateral loads. This is the first time this kind of test is performed in Brazil. Thus, it brings up valuable information about this subject, giving technical information that may contribute to the design and construction of floor diaphragms employing local materials that come from planted forests. The main goal of this research is to evaluate the resistance and rigidity of wood light-frame floor diaphragms, when subjected to monotonic lateral forces acting in the plane of the floor. Full-scale floor diaphragm specimens (2.50 x 5.00 m) were tested with different constructive arrangements, and the influence of the following variables were examined: blocked vs. unblocked diaphragms, rigidity of the nailed joints between I-joists and sheathing; and distance between nails around the perimeter of the OSB boards. The tests showed that the blocked floor diaphragms enable nailing the whole perimeter of the boards, thus increasing its resistance and rigidity. |

Apresenta ensaios realizados pela primeira vez no Brasil, trazendo contribuição inicial sobre o assunto, com subsídios para projeto e execução de diafragmas de piso com emprego de material nacional oriundo do manejo racional de florestas cultivadas. O objetivo geral é avaliar a resistência e a rigidez de diafragmas horizontais, construídos em Sistemas Leves de Madeira, quando submetidos ao carregamento monotônico em seu plano. Para atendimento desse propósito, foram ensaiados protótipos em escala real (2,50 x 5,00 m) com diferentes arranjos construtivos e avaliou-se a influência dos seguintes parâmetros: utilização de dispositivos enrijecedores entre vigas, que constituem a ossatura do diafragma horizontal; rigidez das ligações e o efeito do espaçamento entre pregos na rigidez do conjunto, composto de madeira e chapas de OSB – Oriented Strand Board Nacional. Dos ensaios realizados, conclui-se que o emprego de dispositivos enrijecedores permite o aumento do número de pregos de fixação no perímetro das chapas e esse acréscimo é responsável pelo aumento da resistência e rigidez dos diafragmas.Universidade Estadual De Maringá2010-12-02info:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersionanálise experimentalapplication/pdfhttp://www.periodicos.uem.br/ojs/index.php/ActaSciTechnol/article/view/504610.4025/actascitechnol.v32i4.5046Acta Scientiarum.
