Desenvolvimento de aplicativo para dimensionamento de ligações em madeira de floresta nativa com pinos metálicos

Abstract

Due to the increase use of technologies in day-a-day activities, this work introduces an application for dimensioning native forest wood connection’s, using metal dowels, subjected to traction force in the same direction as the fibers and formed by two or three wood pieces. For this, the formulas and tables were adapted from NBR 7190 (2022) for the creation of the program using the framework React Native, one of the most used nowadays, and which is based on the Javascript language. As a result, the application called DLM was obtained, which calculates the number of metallic pins needed to fulfill the request informed by the user, or even the resistance of the connection according to the number of pins informed, of which can be nails, self-tapping screw or through screws. The program also details the connection according to the values of the wooden pieces entered by the user, specifying the metallic pins distances.
