Design the RC basement wall (a) as a cantilever wall unsupported at the top at the first stage of construction (b) as propped cantilever with the floor acts as a prop at the head of the wall (c) as 2-ways internal panel with all edges continuous. Loading Surcharge 5 kN/m2 Water pressure 10 kN/m3 Concrete density 24 N/m3 Materials Concrete f_eu = 30 MPa for superstructures, Reinforcement f_y = 460 MPa Backfill soil (Gravel)
