The Impact Of Grading On The Structural Performance Of Tensioned End-Joints Of Nailed Laminated Timber – NLT

The most common use of wooden structure in Brazil is the structural frame for roofing. The wood from planted forests, especially southern pine – Pinus spp, is as a good alternative, given that it is a sustainable raw material and with great availability in the market. The trussed rafters system using soft lumber and metal plate connectors is widely used on roofs in other countries. This work proposes the development of the trussed rafters system in nailed laminated timber (NLT), using southern pine to enable the utilization of shorter pieces and smaller cross section compared to the traditional system. Before testing the trussed rafters, tensile tests on end joints were made in NLT specimens with dimension timber. The end joints were spaced…
