Análise da utilização do Concreto Protendido e do Concreto Reforçado com Fibras de Aço (CRFA) como solução para pavimentos industriais

Abstract

The world market for civil construction is constantly evolving. Every day, new innovations in products, appliances and construction techniques appear and shown more effective for a given situation in the daily life of the construction. Due to this evolution, today, in Brazil, it is possible to execute different types of industrial flooring. It is the engineer job to reconcile the best solution with the lowest possible cost, because often new techniques overtax the work, without necessarily bringing a significant improvement to the final result. Among the techniques that the engineer can use, there are the application of prestressed concrete and fiber reinforced concrete. Both techniques give the floors the possibility of overcoming large spans by increasing structural capacity, thus increasing the use of space in the industry and reducing maintenance costs. This project sought to present in more details the indicated solutions, by means of theoretical basis and calculation analysis of an industrial floor made by each of the presented ways. Relevant Limit States were verified in accordance with the regulations adopted. Lastly, a brief budget study of the constructive solutions of this work was elaborated.
