The complexities in designing structures require that engineers be experts in the use of structural
design software. However, many of these programs have complex user interfaces and closed codes. For this
reason, it is often difficult for engineering students to use such programs as educational tools. In this regard, the
Tecgraf/PUC-Rio Institute is developing an interactive graphics open-source tool on MATLAB for structural
analysis of 3D frame structures: the LESM program, which has an intuitive graphical user interface and well-
structured code based on the Object-Oriented Programming (OOP) paradigm. This work describes an extension
of LESM for the design of steel structures based on the Brazilian standard NBR8800:2008. The code
architecture was conceived with modularity, in an abstract OOP fashion, making it possible to extend the
program to handle different steel design codes. The definition and organization of the OOP classes and methods
that were added to the program are presented, in addition to a demonstration of the usability of the software.
