| 摘 要： | 本文研究了素混凝土、碳纤维混凝土和钢纤维混凝土在轴压疲劳荷载下的破坏机理，试验研究了碳纤维、不同品种钢纤维、纤维掺量、加载应力水平对于疲劳寿命及能量吸收的影响规律，探讨了疲劳累积损伤特性。研究表明：在较低的应力水平下纤维混凝土的疲劳寿命、能量吸收值均比高应力水平时明显增大。

| Abstract: | The result of experimental investigation of failure behavior of carbon-steel fiber reinforced concrete under compressive loading is presented.The effects of fiber type,fiber volume and stress/strength ratio on fatigue resistance and energy adsorption are studied.The characteristics of damage accumulation in concrete are also studied.It is found that fiber reinforced concrete may dissipate much more additional energy under low stress level and has logner life than that of high stress level. |
