This paper presents an experimental study on new moment frame connections designed to restrict damage to specific connection elements placed at the bottom flange of the beam. Composite effects and damage to the concrete slab were addressed in these tests. Composite action led to a roughly 98% increase in initial elastic stiffness and 20% increase in yield strength. Meanwhile, the plastic strain at the specific connection elements was increased by only 20%, indicating that the plastic rotation capacity of the connections was hardly affected by the presence of the concrete slab. And the feature of the design forcing the connection to rotate about the top flange was beneficial in reducing damage to the concrete slab.
