REINFORCED CONCRETE BEAMS WITH STEEL FIBERS UNDER SHEAR

摘要: The effect of steel fibers on the behavior and strength reinforced concrete beams under shear is studied. Nine fiber one plain beam were tested by 2-point loading. content ranged from 0.4 to 1 %, aspect ratio was between 60 120. Improvement first crack load ultimate over that noted. first-crack fibrous a function spacing. much higher than beam, depending energy absorbed in debonding stretching fibers, which directly proportional volume ratio.
