Problem 4 Given a retaining wall as shown in the figure. f = 24 MPa fy = 415 MPa 3 6m Soil unit weight = 18.8 kN/m 6.5m 3 Concrete unit weight = 24 kN/m³ Active earth pressure coefficient = 1/3 0.50m 0.7m 0.8m The required strength of the wall, 3.5m u= 0.7 D + 1.7 E where D is dead load and E is earth pressure. Consider per meter strip of wall along its length. Calculate the factor of safety against sliding of the retaining wall. Consider coefficient of friction at the base 0.57. Neglect passive earth pressure at the toe. = Calculate the maximum design moment M, at the stem of the wall. Calculate the spacing of 20 mm Ø bars required at the stem of the wall. Use 85 mm cover to the centroid of stem reinforcements. 2m 0.25 m
