Shear-bearing bearing capacity of stud within negative moment region of continuous steel-concrete composite beams was studied. Based on 3 factors of stud diameter and concrete intensity and steel fiber, orthogonal pull-off tests of stud shear connectors with concrete slab under tension were conducted. The analysis of range and variance shows that, stud diameter has marked effect on ultimate carrying bearing capacity, the influence of concrete intensity and steel fiber can be neglected. Shear-bearing bearing capacity of stud within concrete slab under tension or compression has no visible difference under the condition of degree of connector less than 1 and the stress of longitudinal rebar under yield-point. The cracks appear near studs at first. In the condition of keeping invariableness of degree of connection, the maximum width of crack can be restricted by the methods of lesser diameter of stud and dense collocation.
