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

Q)

The etabs file for a G+6 building is provided. Run the analysis and design the RCC shear walls (show in the etabs model). The following challenge deals specifically with the shear wall of size 300x1500 at grid A-11 in the structural model.

• 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. AutoCAD application can be used for this exercise. Alternatively, it can be drawn by hand as well.
• Provide elevation drawings of the reinforcement details of the shear wall from base up to terrace.

ANS)

given model is opened in etabs and is checked for errors.

after checking for errors, we go to display bars from the shear design tab and subselect longitudinal bars.

area of longitudinal bars is obtained.

after that values for shear reinforcement is obtained.

then lengths of boundary elements is obtained.

after taking these values calculations for bars is done as shown below.

cross sections and elevations of shear walls along each wall is shown in figure.
