Cálculo de la estructura metálica de una nave industrial y análisis de diferentes técnicas de protección pasiva frente al fuego

Abstract

The aim of this project is to design and calculate the steel structure of an industrial building in the city of Villarreal, in the province of Castellón, Valencia, Spain. This industrial building will be dedicated to the storage of electronic equipment. Subsequently, the application of different methods of passive fire protection will be studied and compared. Firstly, the design and the calculation of the steel structure will be carried out by using specific software. The design is conditioned by the necessities of the future use of the industrial building and its location. The calculation of the structure will be performed in accordance with the national standard CódigoTécnico de la Edificación. The second part of this work will be to evaluate several techniques of passive fire protection and make a study to determine which one is the best solution from the economic point of view. The different cases studied are unprotected sections and four other scenarios which include different types of passive protection: rock wool, plasterboard, mortar projection and intumescent paint. This second part will be developed according to the corresponding standards. Again, theCódigo Técnico de la Edificaciónwill be employed, specificallytheDocumento Básico de Protección en caso de incendio (CTE DB-SI). Sincethestructurewill be hold industrial facilities, theReglamento de Seguridad contra Incendios en los Establecimientos Industriales (RSCIEI, Real Decreto 2267/2004) will be usedtoo. According to these standards, the structure safety requirements in case of fire will be defined and established taking into account its characteristics. Then, for each case outlined above the required passive protection will be calculated and described with detail. Finally, an economic study of each option considered will be carried out. This analysis will be developed in order to compare the different techniques used, so it will be possible to determine which is the most appropriate method to be applied from the economic point of view.
