Abstract

ABSTRACT: This work is focused on lightweight wood-frame constructions, presents a finite element modeling of floor diaphragms and wood I-joists subjected to four-point bending. It presents the results of experimental tests on wood I-joists subjected to vertical loads. The main goal of this research is to evaluate the resistance and rigidity of wood light-frame floor diaphragms, when subjected to monotonic vertical forces acting in the plane of the floor. The analysis by the Finite Element Method was performed by SAP2000 computer program were tested with different constructive arrangements, and the influence of the following variables were examined: distance between wood I-joists and distance between nails around the perimeter of the OSB boards. Finally, a comparison between experimentation and analytical results are performed, some conclusions are presented demonstrating that the OSB, used as subfloor elements in horizontal diaphragms, are responsible for the redistribution of the load and the influence of the different systems of connections used.
