Abstract:
Under the American design standard, ACI 318, the strength of slab-column connections is assessed using an interaction equation that includes contributions from both shear and unbalanced moment. Based on a reexamination of tests reported by Hanson and Hanson, the unbalanced moment at interior connections is shown to contribute far less to transverse shear than is assumed in design. A simple limit analysis is presented. This analysis is more consistent with observed behavior and accepted material limits and better predicts the test results.
