Brittleness of Reinforced Concrete Structures under Arctic Conditions,
Abstract
The behavior of reinforced and unreinforced concrete beams was studied under impact loading at low temperatures, and the results were compared to the behavior of reinforcing steel (rebar) in Charpy-V impact tests. Transition temperatures as low as -30 C were obtained for the rebars in the Charpy-V tests, whereas no brittle failures occurred in the rebars in the reinforced concrete beams at temperatures as low as -63 C, even in beams where the rebars were intentionally notched. The impact strength of unreinforced concrete increases considerably at lower temperatures, thus reducing cracking of reinforced concrete structures and significantly increasing the safety of lightly reinforced structures.
