Steel Structures has been gaining more and more space within civil construction, due to aspects such as lightness, execution speed and cleanliness, and even for becoming a viable option for various situations, and aiming at these aspects the constructive system of light steel structures, known as Light Steel Framing (LSF), allows this rationalization of characteristics through the industrialization process of the elements of a building. Thus, the work developed allows the understanding of the system as a whole, its particularities, construction processes, methods adopted, material characteristics, profile behavior, design characteristics and calculation considerations. Given the technical and theoretical characteristics of the system, the structural design along with the design and modeling of the structure follows, a process developed through mCalc3D and mCalcLSF Software, both from STABILE, aiming at the Brazilian standards ABNT NBR 8800(2008), ABNT NBR 14762(2010), ABNT NBR 15253(2104) and NBR 15575(2013), in which the resistant efforts for each profile and the maximum displacements that the structure allows are evaluated, in order to enable the most adequate sizing possible. Finally, estimates of the number of profiles to be used are briefly made so that in future work, the economic feasibility of this system can be studied in comparison with traditional construction methods, considering that, according to the results, steel has a higher cost than reinforced concrete in terms of material itself.
