how to design the basement walls fir the vertical loads?
is it correct to take 1feet strip and check for stresses against vertical loads and provide the required reinforcement just like the slab is designed?
General Basement Wall Design.
take a unit strip, if your basement wall has a slab on top, you can treat it as a propped cantilever with Ko (Coefficient of Static earth pressure: as wall cant move to Ka state for failure).. If cantilever, design for lateral loading with Ka(Coefficient of active earth pressure).
Significant Vertical Load
If you have significant vertical load design it as a beam column and use ACI wall provision for min/ max reinforcement.
