Abstract

The reduction and shortage of natives forests in south and south-east regions in Brasil happened specially because their continuous and incontrolled exploration. This fact and the governamental incentives provided large areas of planted forest. So, several Pinus species were taken as alternatives source for obtaining wooden structural pieces previously classified and preserved against biological attack. This work aims to demonstrate the technical viability of using Pinus timber in trussed roof structures. As final conclusion of the work, comparative tables related to wood comsuption per unit covered area and the joints comsuption are presented. The utilization of Pinus lumber in civil construction, demonstrated its technical and viability, will constitute an expressive alternative, taking in account the implantation, the exploration of these planted forest. So, it will keep equilibrated the wood deal that, in addition to the short distance related to the consumer centers, will conduct to a accessible final cost. At last, the full utilization of the planted forest permits desinable reduction of the extensive exploration of the brazilian native forests. (AU)
