The strip model describes a load path prior to failure that can be tailored to a wide range of slabs under concentrated loads, both concentric and eccentric. Eccentric punching shear can occur in concrete slab-column connections subjected to shear and unbalanced moment, such as edge and corner columns. This paper shows how the strip model is applied to experiments of edge column-slab connections tested with outward eccentricities, and compares this approach to the traditional and simplified ACI 318-19 approaches for dealing with eccentric punching shear. This work shows how a lower-bound plasticity-based model can be used for the practical case of the slab-column capacity for edge and corner columns, how it may explain the mechanics behind the ACI code provisions, and can help researchers identify adequate test setups for future experiments.
