Elementos estruturais em madeira: desenvolvimento de programa computacional de dimensionamento

Abstract

Wood is a material that shows several favorable characteristics, like its relation between endurance and weight, its sustainability, the materials easiness to handle, the fact that it's a good thermal insulator, among other things. Because wood is a natural building material it's susceptible to biological flaws and has several imperfections, like knots and crevices. Although, with the advancement of technology, these negative aspects are easily handled with the use of industrial products for each situation. Thus, making wood a durable and high quality building material. The use of wood as a structural material is still very little explored because of the fact that there is still prejudice against the material for the reasons stated above and also for the lack of research on this subject. Therefore, this study has as its objective the development of a computer program for dimensioning structural elements in wood, following accurately the requirements of ABNT NBR 7190:97. The software was developed on IDE NetBeans 8.2 using Java coding and it was divided in 9 different tabs, where which of the tabs has its specific function to improve the users experience. Among these flaps are the dimensioning flaps of structural elements in wood (sic).
