摘 要：Effects of high temperature on the compressive and splitting strength of the steel-fiber reinforced concrete （SFRC） with different content of steel-fiber were investigated and its mechanism was simply analyzed.Results indicate that the compressive and splitting strength of SFRC decrease slowly within 400 ℃ and they decay a little faster when over 400 ℃.The residual compressive and splitting strength rate of SFRC （2% fiber） increase about 27.6% and 9.3% of that of the control concrete without steel-fiber,respectively.The finite element software ANSYS was adopted to analyze the temperature field and stress field of the steel-fiber reinforced concrete at 400 ℃.The simulation results can further explain the effects of fiber content on the thermal field and stress field in SFRC and forecast the crack tendency of SFRC during heating process.
