How to Calculate Bending Moment Diagrams? The overturning moment is the sum of the horizontal forces times the distance to the footing base. The moments are obtained by multiplying the story shear by the distance to the center of mass above the elevation consid ered. 6. It is enlarged from figures in NBS discussion of national electrical safety code (handbook H39). In this design, the wind forces on the sails will result in an overturning moment which counteracts the overturning moment generated by the action of the wind on the V-shaped arms, and therefore the effect of the sails is a net reduction in the algebraic value of the overturning moments. This process continues until zero moment and shear at the base are obtained. The best way to judge this is to multiple the wind load by a factor equal to the Safety factor and to see if the footing still works. This is important for footings with eccentric pedestals where the vertical loads will have different stabilizing effects for each face. Thus, the component of the overturning moment resulting from the shear at the base of the supported member acting over the footing thickness is not accounted for. Distribution of wind pressure co-efficient Cp and response analysis is also evaluated for these models. Whats the physical value of mass moment of inertia? Multiply the Grms by the height of the center of gravity. Similarly, the de-stabilizing load would be viewed as the sum of the moments about the edge of the footing.
