The following elaborated work will explicitly show the behavior of trusses used as support structures for roofs or other elements that require it in civil construction, note that this is for academic use which will serve efficiently to solve said trusses, layers to give exact results such as: internal forces, displacements and reactions and also visually discriminate the shape of said structural element in 2 dimensions, the aforementioned will be executed through the matrix analysis of trusses, using the software called as the only systematic tool.
