N2  - The subject of this study is to improve the previous computational model for computing  shear capacity of reinforced crack.  The reduced axial stiffness of reinforcement caused by crack shear in concerete has been  investigated in this study. Experimental shear stress-shear slip and steel strain-pullout results in  reinforced concrete member are given. At the crack plane, steel stress-pullout relationship and  its mechanical behaviors are experimentaly found to be quite different from the relationship  previously obtained under uniaxial stress condition. The distribution of strain and curvature  nearby the shear crack has been investigated. The high curvature induced in bar nearby the crack  section has been found to be the main reason responsible to the reduced axial stiffness of bigger  diameter steel bar and causes the premature failure of reinforced concrete after crack.
