The Crack Width Control Effect of a Component in Short Aramid Fiber Reinforced Concrete Member

SupervisorFProf.Takumi SHIMOMURA

Each fiber reinforced concrete member carried out axial tension test. Fiber reinforced concrete member checked experimentally that it was effective in reduction of the crack width of a component. The crack width reduction mechanism by fiber mixing studied.
Consequently, it became clear that it cannot explain from a viewpoint which tension-stiffening of concrete and crack interval.
The bridging effect of the fiber in a crack checked that it was the main mechanism of crack width reduction.
The crack width calculation formula of fiber reinforced concrete was proposed.
