Three-dimensional (3D) simulation of 3,10 and 20 story buildings were exposed to compromised column scenarios providing an insight to the inherent robustness and structural integrity of moment-resisting frames. The methodology proposed, validated for quantifying the catenary and membrane mechanism in concrete floor system and structural floor framing system, and identification of provisions for successful activation of catenary and membrane action in framing system. The base system included 2VLI22 steel deck and 66-W1. 4DW1.4 welded wire mesh reinforcement. Due to the addition of mild steel reinforcement, membrane action in slab system is effectively enhanced. The distribution of mild-steel slab reinforcement in the exterior bay appears to be economical in enhancing the inherent structural integrity. The analysis conducted indicated that it is likely more beneficial to have smaller moment capacity and flexural stiffness for connections distributed throughout the floor framing;
