The wind force Is applied at midheight to calculate the overturning moment. The resisting moment Is based on the empty weight of the tank acting act the centerline of the tank. In all cases, there is net overturning for wind on an empty tank. The tank has been stabilized for this condition by the addition of cable bracing. The cable and anchor forces are determined based on the force required at the top of the cable (Ph In Table above) to stabilize the tank for overturning In wind. In all cases, seismic forces govern for design of base shear anchorages. Note: Where seismic foces govern overturning, the required resisting moment (Mc In table above) corresponds to the net seismic overturning moment.
