Desenvolvimento de um aplicativo android para dimensionamento de lajes nervuradas treliçadas

With new technologies and the speed of data processing, various activities have been updating, innovating and seeking new ways to solve problems. The aim of this work is to develop a tool for Android mobile devices to verify ribbed slabs with preformed beams using the MIT App Inventor 2 environment, associating computational logic and civil engineering, and using the application as a didactic tool. Many works prove both the versatility of the ribbed slabs with preformed beams as well as the utility and creation possibilities with MIT App Inventor 2. Studies in the pedagogical area show that the programming associated with teaching has presented good results. The ribbed slabs have advantages associated mainly with the reduction of their weight, leading to larger spans and a certain reduction of costs. The Lajedo application was developed in MIT App Inventor 2 using structural theories for unidirectional slabs and presents worksheet-compatible results in Excel software by validating their calculations through analytical resolution of exercise.
