Abstract:
The Brazilian standard ABNT NBR 15200 is in revision. Some omissions on the design of beams in the 2004 version of the standard will be included now. Possibility of reduction of c1 in situations of safety reserves, different design for unidirectional ribbed slab and lateral increase in c1 in some cases are the cases of interest in this work. The Eurocode provides recommendations on these items, however, they are not considered adequate to Brazilian design. The objective of this article is to perform thermal or structural analyzes of reinforced concrete beams and propose alternatives to the recommendations of Eurocode in order to standardize them at this stage of revision of the Brazilian standard.
