Abstract:
The Brazilian standard ABNT NBR 15200:2004 - Fire design of concrete structures gives a tabular method to the fire design of concrete columns, which associates the load level and the minimal dimensions of the cross-section and the place of the reinforcement centroid to the required time of fire resistance. This paper presents the theory of those tables and a study as a contribution to a future review of NBR 15200. A structural design more optimized, more correct and economic than the tabular method given by the Brazilian standard can be attained using alternative methods.
