玄武岩纤维钢筋混凝土梁弯曲静载及疲劳性能试验研究

In this paper, based on static load and fatigue test, analysis of basalt fiber reinforced concrete beam under static load and repeated bending load failure pattern and failure mechanism, deflection change rule.?The results show that: basalt fiber reinforced concrete beam on the ultimate bearing capacity is enhanced, the maximum amplitude is 6.5%.??Basalt fiber reinforced concrete beam fatigue failure mode of brittle failure, began in the fatigue fracture of reinforcement.?Deflection with fatigue cycles - grew larger, and later in a stablephase amplitude changes relatively small.?Through the fatigue life of basalt fiber reinforced concrete beam with the curves load cycles, fitting a different volume content fatigue life equation.Provide the basis for basalt fiber in the practical engineering application.
