Abstract

The article presents results from the research into fire temperature influence on steel-concrete bond and on the bond reduction for both in-fire and after-fire status. Bond tests and its results for materials St3S, 18G2 reinforced steel and C16/20, C40/50 concrete, have been described in the article both for in fire and after-fire conditions. All tests have shown a significant reduction of steel-concrete bond as a result of fire temperature. It was proven, that significant bond differences exist between in-fire and after-fire tests, what demonstrate that the bond is regained partially after the exposure.
