Seismic overturning moment formula
WebOnce the seismic overturning moment is calculated, the code then requires that the vertical stress in the shell be less than the buckling stress (this is a good provision), as calculated using the traditional σ = M/S. For a shell annulus with D(inside) = 140 feet and t = 0.60 inches, S= πdoutside 4−d inside ()4 32doutside Webthat apply to lateral force resisting systems: moment frames, shear walls and braced frames. 4.4.1 Moment Frames Chapter 4.0 - Evaluation Phase (Tier 2) ... loads, but are known to have small seismic overturning forces. When both demands are large, the combined effect of gravity and seismic forces must be calculated to demonstrate …
