Abstract:
Based on a beam analogy concept, a two-dimensional (2D) nonlinear model for interior slab-column connections was developed for use in pushover analyses of flat-plate structures. The slab lateral resistance from flexure and shear acting on the connection was modeled by an equivalent beam element and the resistance from torsion by a rotational spring element. The parameters defining connection lateral stiffness were calibrated from the tests presented in this study and were validated using experimental data reported in other studies.
