"Light Steel Framing" (LSF) is a constructive system with a rational conception for industrialized, large-scale, manufacturing and assembly of buildings from domesticscale, almost all dry, where the cold-formed members, in galvanized (zinc coated) steel plate of small thickness, are used in the composition of walls, beams of floors and roofs. The present research deals with the numerical analysis of structural components by finite elements method of residential buildings of four and seven floors structured in the LSF system, where different proposals were considered in architectural and structural conceptions. In order to determine the load in the structures, as well as for the analysis of the global stability of the building, a commercial structural analysis program was used via Finite Elements Method (FEM), where linear and non-linear analysis had been carried through, including the consideration of the geometric second-order effects (P-Delta) in the evaluated structures. The diaphragm effect in the hardening of wall panels with OSB plates was also considered, with the evaluation made by means of two different theoretical methodologies. As result of this work, it was verified that the technology is perfectly adaptable to buildings with up to seven floors, taking into consideration the cross-sectional of the frames used by the norm NBR 14762, as well as the detailing of structures for determining steel consumption.
