    Análisis de los elementos estructurales utilizados en el diseño de una edificación de dos pisos con un sistema estructural liviano (Steel Framing)

    The development of civil construction leads to industrialized and modern construction systems. One of these is Steel Framing (SF), cold-formed galvanized steel profiles enclosed by cement board, wood or gypsum board panels. In the Ecuadorian environment there is concern about the safety of its structural components. The seismic demand to which the country is subjected requires the construction sector to innovate construction systems, especially for the residential building sector, in order to carry out construction processes with less environmental impact and better seismic resistant behavior that guarantees the safety of the occupants. The materials used in the SF construction system lack reliability in the local market, since they are in a discrete commercialization state due to their low demand and limited consumer scope, which is mainly composed of professionals dedicated to real estate projects. In this study, the structural design of a 2-story residential building was carried out, verifying the mechanical properties of SF by testing its main structural elements. The samples were extracted from profiles available in the market and were analyzed through mechanical tests in several laboratories in the country. During the tests, tensilexvi behavior, metallography, hardness, chemical composition, electron microscopy and coating thickness measurements were evaluated. The results showed that the structural elements that make up the SF system meet the mechanical requirements requested by the structural design standards and its application is feasible in the proposed building, taking into account the good quality of the material used in the manufacture of the profiles used in this construction system. In addition to the results obtained numerically, it is important to emphasize the advantages of the SF, in terms of weight of its elements (light structures), speed of execution and good environmental practices in the construction process.
