In particular an analysis of the options given by the TechnicalBuilding Code, in Spain (CTE, Código Técnico de la Edificación, at its core document SI,Seguridad en Caso de Incendio, (Safety in case of fire) when seeking to determine therequired fire resistance of structural elements, and also the study of the actual fire resistanceof these structures. Too, it is necessary to justify the behavior of steel structures to fire tobuildings in which at present is not even raised by the use, making a combined analysis of theequivalent time, the calculation of real temperature in the area in case of fire, the passiveprotection fireproof and the special steels of high resistance to fire. With the ultimate goal thatthe steel structures to recover some lost ground with concrete.37º <strong>IAHS</strong> <strong>World</strong> <strong>Congress</strong> On Housing Science 94
