2. The cantilever retaining wall resists active lateral earth pressure throughout its length. Given: a= 0.25m b= 0.55m c=0.55m Unit weight of soil = 17 kN/m³ Unit of concrete = 24 kN/m³ d=2.8m e=6m H=6.5m Active earth pressure = 1/3 Neglect passive earth pressure at the toe. Consider per meter strip of the wall along its length. Calculate the total lateral force in kN on the wall due to active pressure. Determine the overturning moment (OM) in kN m 6.5m to. 0.50m

additional given/ replacement: fc'=21mpa and fy=415 mpa 2. solve and give the correct answer foundation and retaining wall 2. The cantilever retaining wall resists active lateral earth pressure throughout its length. Given: a= 0.25m Ha b= 0.55m d=2.8m e=6m H=6.5m c=0.55m Unit weight of soil = 17 kN/m³ Unit of concrete = 24 kN/m³ Active earth pressure = 1/3 Neglect passive earth pressure at the toe. Consider per meter strip of the wall along its length. Calculate the total lateral force in kN on the wall due to active pressure. Determine the overturning moment (OM) in kN.m due to lateral earth pressure. 6.5m b 2.80m How much is the moment (RM) resisting the overturning moment? Determine the factor of safety against the overturning moment. (FS=RM) 0.50m Determine the ultimate moment at the wall stem. Determine the number of 20mmØ bars required at the stem of the wall. Use 75mm cover to the centroid of stem reinforcement.
