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

DESIGN SHEELL WALL

elevation drawig of reinforcement

procedure:

• Extract values of longitudinal steel ratio, boundary element length and shear reinforcing ratio from the design results.
• Provide cross sectional steel arrangement of the shear wall from its base up to terrace, in compliance with provisions of IS 13920 – 2016.

• 1/3rd of min member dimention =300/3
• 6 times smallest main bar =6*25 =150mm
• 150mm permisible if verticle bars are spaced at max 200m
