“Ligaço”: um aplicativo android para verificação de ligações aparafusadas e soldadas

Abstract

The present work applies the knowledge of screwed and welded metal connections, according to ABNT NBR 8800 2008, for the construction of an application for Android devices using the LAMW - Lazarus Android Module Wizard development framework. The Application LigAço developed in this work is able to calculate the effort resistant of structural metal connections in elements of the type: plates, flat bar, profile I, profile H, profile angles and profile U connected in the following arrangements: bolt with straight drilling; bolt with zig-zag drilling; fully penetrated welding; partially penetrated welding and fillet welding. The results obtained using the automation tool LigAço are comparable to those reported in the reference literature and can be used in professional and academic activity with significant advantages when compared to the analytical calculation (handmade) for providing solutions quickly and accurately for the cases of connections bolt and welding of laminated and welded elements. The LAMW framework proved to be efficient and versatile, standing out for the usability and ease of learning, living up to the RAD paradigm - rapid application development environment, and it can be an interesting option for the development of applications in the engineering areas.
