ANÁLISE COMPUTACIONAL DE ESTRUTURAS METÁLICAS VIA MASTAN2

Abstract

The use of computer programs for analysis has become increasingly recurrent due to the optimization of processes and the practicality they provide. In this sense, the traditional analysis process based on analytical solutions has been complemented by software that greatly assist civil engineering students, professionals and researchers. Currently, the Instituto Federal Goiano - campus Rio Verde does not have its own software to perform matrix analysis of threedimensional structures considering physical and geometric nonlinearities. A software with these characteristics would be essential for the learning of students in civil engineering disciplines and for master's students in the Graduate Program in Applied Engineering and Sustainability, in addition to being able to promote the production and publication of articles in the structural area. Thus, MASTAN2 appears as a viable alternative for having the ability to perform 2D and 3D analysis, considering the physical non-linearity, geometric non-linearity, among other parameters. The present work consists of an initial project that aims to present the MASTAN2 software, providing basic notions for its use and for obtaining diagrams of solicitant forces and displacements in first-order elastic analyses. For this, it is about demonstrating several cases subdivided into 8 models of specific efforts in metallic structures, seeking to cover the greatest number of possibilities and their analyses. The first 4 models consist of applying loads, torsor moment and displacement in a mono-mounted beam. The fifth example is a double-mounted beam with applied temperature variation. The sixth model consists of an inclined beam with a distributed transfer length. The seventh example shows the application of torsor moment on a beam that is exposed on 3 axes. The last model brings a second order analysis of a frame preestablished by the software. From these applications and evaluations, several values of requesting efforts and loads compatible with those reached by analytical solutions are obtained. Consequently, a didactic manual is obtained that will help civil engineering students and professionals in the use of the program, in addition to results similar to those found in the literature, attesting to the software's capacity and its feasibility for use by all students and civil engineers.
