Characterizing of steel used in the construction of civil works in Almeria

Abstract:

[en] Various tests have been conducted on the steel bars used in the construction of civil works in Almeria (Spain) during the period 18 January 2000-7May 2001, with the aim of mechanically characterizing the different types of steel (weldable; B400S, B500S and ductile weldable: B400SD) to determine whether there is a technical reason for the increase in the use of ductile weldable steel. For this, we have used a hydraulic machine to break by traction all the test samples that arrived to the laboratory, following the specifications of the UNE 7474-1: 1992 and the UNE 7474-2: 1992. The results indicate that only in 86% of the cases does the steel B400SD satisfy the limits specified by the UNE 36065: 1999-EX, as opposed to 95 and 94% of the B400S and B500S steels. In addition the ductile weldable steel registered mean values lower than those of B400S. This findings disagrees with expectations set by the specifications.(Author) 6 refs
