Abstract: The yield strength of the steel rebars is one of their essential characteristics considered in the safety checking of reinforced concrete structures. It may present substantial variations, due to the influence of different factors This paper presents a statistical study of the yield strength Re of A500 steel rebars used in Portugal, from three different ductility classes according to the Eurocode 2. The statistical distributions of Re are based on a very large collection of more than 30 000 test results, obtained from 1994 to 2019. These rebars were produced by several dozens of different manufacturers, mostly from foreign countries. The detailed data presented here, about the main statistical parameters of the Re distributions and their variation with the rebars grade and diameter, for instance, may be useful for different studies,such as structural refurbishment projects to evaluate the safety of existing structures, in their actual state or after their restoration.
