Unformatted text preview: using Richards and Elms formulation. If the top width of the wall is given as 3 meters, what should be the width at the base of the wall to fulfill the minimum weight requirement? Assume unit weight of concrete as 24 kN/m 3 d) Estimate the displacement of this gravity wall by using Richards and Elms method.
