Abstract
Studs are often used as shear connectors or anchors between concrete and steel members at various composite structures. Generally as each stud has different edges distance from the edges of structural concrete, it is not expected that they have same pull-out and shearing strength as the studs located enough inside, even if all studs were arranged in a group to be subjected same displacement.
In this paper, the authors evaluated again test data of previous investigation including their new test results and strength equations for pull-out and shearing capacities were revised in the case of free to consider the edge distance. Then in the case of the studs to be considered the edge distance, new influence factors were found and composed into the revised equations as coefficients.
