Verificação experimental de carga critica em pilares de madeira de acordo com a NBR 7190/22

Abstract

We learned from the beginning of graduation, the responsibility that an engineer has, whether to execute a work, or to design. It must always follow the rules that are made available. The use of wood in civil construction is growing every day, as it is a renewable raw material that generates less waste than other materials. Like any other type of material, ABNT guides the engineer on how to design using wood efficiently and safely, this standard is NRB 7190, which in 2022 received an update, the last revision was made in 1997. In this standard we can find guidelines on the dimensioning of columns and verify their stability, which is exactly the purpose of this work, the first idea was a practical and theoretical comparison, using the standard and tests proposed in it. But with the revision of the standard, it was also possible to compare with its revisions. The work also made possible the contact with the raw material that is offered in the local trade, which often does not have any record about its origin and quality, which can also be observed in the results obtained. Keywords: Pillars, engineering, standards, wood, construction.
