Given:

This wall’s weight is 145 lb/CF

The design wind pressure is 20 lb/SF

For moment calculations, the wind can be assumed equivalent to a point load perpendicular to the wall at the midpoint of the exposed wall

Which of the following statements is most correct? Ignore the weight and overturning resistance of the footing and calculate only the moments at the bottom of the vertical portion of the wall.

Options:

• The overturning moment is greater than the righting moment and therefore the design needs to be further stabilized
• The overturning moment is greater than the righting moment and therefore the design is adequate as-drawn
• The righting moment is greater than the overturning moment and therefore the design needs to be further stabilized
• The righting moment is greater than the overturning moment and therefore the design is adequate as-drawn
