[2146] NUMERICAL INVESTIGATION OF EFFECT OF THROUGH CRACK ON SHEAR STRENGTH DEGRADATION OF RC COLUMN
Keywords:cyclic loading, RC column, shear strength degradation, through crack
When a RC member is subjected to cyclic loading, shear failure often occurs after flexural yielding because of shear strength degradation. The effect of through crack on shear strength degradation was numerically evaluated by assuming that through cracks, caused by residual deformation of tension rebar after yielding, probably lead to shear strength degradation. As a result, by generating through cracks at around the height of column effective depth, the knowledge that shear strength degraded remarkably with increase of crack width was acquired.
