【 摘 要 】

The results obtained by experimental determination of residual mechanical properties of high-strength concrete after fire exposure are presented. The following properties are analyzed: compressive strength and tensile strength, and the tangent and secant moduli of elasticity. The testing is conducted by heating concrete samples to a high target temperature. In addition to mechanical properties of concrete, other properties registered after sample cooling are also presented. The results are compared with corresponding properties given in EN1992-1-2 and EN1994-1-2.
