摘要
在国内外有关钢纤维混凝土疲劳特性研究的基础上,试验研究了低温下钢纤维混凝土梁抗折疲劳特性。试验结果表明,应力水平对低温养护钢纤维混凝土梁抗折疲劳寿命产生显著影响,低应力水平下的疲劳寿命远远高于高应力水平下的疲劳寿命。
On the base of the domestic and overseas fatigue research on steel fiber reinforced concrete （SFRC）, the flexural fatigue feature of SFRC beam is researched according to the basic mechanics property investigation of SFRC at low temperatures. The test results indicate that the stress level has significant effect on the flexural fatigue life of SFRC beam under low temperature curing. The fatigue life under low stress level is much higher than the fatigue fife under high stress level.
