Estudo de caracterização física e mecânica da madeira Pinus Elliottii

Abstract

For this study, the characterization of some physical and mechanical properties of wood of the species Pinus Elliottii var. Elliottii was performed. Regarding the mechanical properties, tests were performed to obtain the normal and parallel compressive strength of the fibers, as well as the shear strength test parallel to the fibers. Also, moisture content and basic density tests were performed to define these physical properties. These tests aimed to define the parameters of wood strength that are used in permanent and temporary constructions in Alegrete - RS and region, since there is little research related to wood, both at state and national levels. The results obtained were compared with data from NBR 7190 (1997) and other related studies. It can be observed that the wood used didn’t reach the expected strength values, i.e., if the designers take as base the average values contained in NBR 7190 (1997) for the dimensioning of wood structures with the material studied, the project wouldn’t meet the safety criteria.
