Abstract
A tall building () includes a plurality of ray structures () extending outward from a central, generally conical hollow reinforced-concrete core (). In three of the rays (), a frame () extends diagonally downward and outward from the core. If a building floor located above the barrier falls onto the floors extending outward from the barrier, the latter floors will fail in such a manner as to cover the barrier frame and shed all floors that fall onto the resultant barrier from above it. A chain-reaction failure caused by failed floors falling on successively lower floors is thereby interrupted, and floors below the barrier are protected from damage by floors that have fallen from above the barrier.
