Abstract

One of the most significant behavioral characteristics for bolted connections results in prying action and slip in that ultimate strength capacity as well as energy dissipation can be determined based on these mechanisms. The experimental programs considered herein were performed to isolate the heavy clip-angle component of bolted moment connections so that an economic parametric investigation on prying action and slip mechanism should be conducted. So, in this paper, the proposed prying and slip model are evaluated by comparing their predictions to the results of experimental component tests with respects to failure modes, ultimate clip-angle capacity, and slip resistance. Thus, the adequacy of both proposed models generally used for connection design is validated through the comparison.
