Data on the bond strength of 2 concretes and 3 steels at high temperatures

In order to assess the structural response of reinforced concrete in fire, a major research programme was initiated under the umbrella of the Hiper project which involves the testing of the steel, concrete and the composite by means of pull-out tests. Such a comprehensive programme is unique. The tests are partly funded by Hiper and partly by Professor Gabriel Khoury of FSD and Imperial College to provide a comprehensive panoramic view of the effect of fire on reinforced concrete structures and to examine the influence of three types of steel - carbon, AISI 316 Stainless and especially the innovative HSS3 Conge stainless steel. Although the casting was made in December 2004 and January 2005, the steel tests and over half of the concrete and pull-out tests have already been completed. While not part of the Hiper programme, tests on plain concrete are necessary in order to ascertain the thermal stabilities of the two concretes examined: limestone and granite, the latter being the more stable. For the pull-out tests, the pull-out failure induced by shearing off (corresponding to well-confined bars) and pull-out failure induced by splitting cracks (corresponding to less confined bars) are investigated. Furthermore, all tests are conducted at Imperial College, London, in the traditional "steady-state" temperature methodology as in the codes and standards, and by an innovative "transient" thermal test methodology more representative of fire conditions.
