Abstract: After high temperature, such as a fire, reinforced concrete undergoes a series of changes in its mechanical properties such as compressive strength, tensile strength and bond strength between the steel and concrete. Mechanical properties of reinforcement and concrete and bond-anchorage properties of bars in concrete are summarized and analyzed systematically.
Keywords: after high temperature; reinforcement; concrete
