Análise de estabilidade e de resistência de pilares de madeira de seção composta no município de Delmiro Gouveia - AL

Abstract

Although it is widely used in roof structures, wood is poorly applied in other types of structures in Brazilian buildings. However, it is not difficult to find constructions, in which, the wood is applied without any structural unification, above all, in the residences of lower standard. This improper practice generates additional costs and does not guarantee structural safety, so it is necessary to develop studies that promote the reduction of the raw material loss index and the safety of techniques used in the construction of structures. In this way, this work involves the analysis of 15 composite section wood pillars, located in the city of Delmiro Gouveia - AL, according to the methods described in NBR 7190 - Timber Structures Project (1997). In the study, stability and resistance checks were performed only on the structures ensured by the standard and the constructive's inspection and geometrical pillars' characteristics. Finally, in terms of results, the procedure of stability analysis and resistence meet the requirements, but it was possible to perceive the non-compliance with the construction techniques of the wooden pillars established by this standard.
