钢纤维对高强混凝土高温作用后力学性能影响的研究

Research of the steel fiber influence on the mechanical property of HSC after high temperatures

通过对钢纤维高强混凝土高温后力学性能的试验研究,探讨了钢纤维高强混凝土的抗压强度、抗拉强度和抗折强度在不同温度下的变化规律。与高强混凝土火灾后性能变化规律进行比较,分析了钢纤维对高强混凝土受高温作用后力学性能的影响机理。

Through the experimental study on the mechanical property of steel fiber reinforced high strength concrete（SFRHSC）after high temperature, the paper discusses the influencing law of the compressive strength, splitting strength and rupture strength of SFRHSC under different temperatures; compares the changing rule of SFRHSC to that of high strength concrete（HSC） and analyzes the influence mechanism of steel fiber to the mechanical property of HSC after high temperatures.
