Analysis & Design of RCC shear walls in the model using ETABS

• minimum reinforcement for shrinkage and temperature.
• ultimate limit state design rebat reqired.
• ductility rebar requirement.

among these three which is greater should be drawn in RC shear wall detailing

• classification of shear wall as per IS 13920-2016 clause 10.1.4
