Procedimentos para enquadramento em classe estrutural de resistência da madeira de Pinus sp.

Abstract

The development of products that meet the needs of society through raw materials efficient and low environmental impact is a challenge for all researchers in the country. Madeira is an interesting and viable proposal of use for buildings, it can be used in different types of structures, offering high quality, performance and ecology. This study aimed to make a simplified characterization of Pinus sp., Via parallel compression tests to the fibers, for framing purposes in structural classes, according to the recommendations of NBR7190 standard. For the development work random samples were taken from a batch of timber 3.5 m³. The bodies of the test piece were divided for the apparent moisture testing, basic density and resistance to compression parallel. After the mechanical test was determined by the modulus of elasticity (MOE) in the parallel direction of the fibers, based on data obtained in parallel compressive strength test fibers. the results for the apparent moisture test were found, basic density and resistance to compression parallel, however the variability of the sample in the frame prevented structural class and determination of modulus of elasticity.
