Moment of Inertia Definition. Though no structures of this type had yet experienced strong earthquakes, in the early 1960s, engineers placed language in the Uniform Building Code (UBC) requiring that all buildings, in excess of 13 stories or 160 feet in height, be provided with a moment-resisting steel frame capable of resisting at least 25% of the required seismic forces. This configuration is able to resist lateral and overturning forces because of the bending moment and shear strength that is inherent in its members and the connecting joints.
