Unformatted text preview: net dynamic thrust and its point of application on the wall during this earthquake scenario by using Mononobe-Okabe (1921, 1926) method. c) Estimate the displacement of this gravity wall by using Richards and Elms method. d) Estimate the minimum wall weight required to ensure stability of the gravity wall by 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 Assignment 8 : Seismic Assessment of Retaining Structures 4 m 2 m 4 m 2 m Sand wet =18 kN/m 3 c = 10 kPa =30 Sand sat =19 kN/m 3 c = 5 kN/m 2 =32 15 20 kN/m...
