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

Aim

1) Run analysis and design RCC shear wall

2) Extract values ​​of longitudinal steel ratio, boundary element length and shear reinforcement ratio from the design results.

3) Provide elevation drawings of shear wall reinforcement details.

Introduction -

Procedure -

Step 1)

i) Open prompts 9 file and download it.

ii) Open this file in Etabs software


Step 2)

i) Check the model for any error before analysis

ii) Click Analyze - Model Check

iii) You will see the following dialog box


Step 3)

i) Now run the analysis

ii) Once the analysis is done

iii) Click Start Design Check for Shear Wall


Step 4)

i) Once the design review process is complete.

ii) Click on Design - Shear Wall Design - Display Design Info -
iii) Once you click on Show Design Walls

iv) Click on Display Output -



1) Click on - Pier Gain Ratio

2) Longitudinal reinforcement of the pier -

3) Pier edge / border zone width -

4) Pier shear reinforcement

Step 5) - Calculation of shear wall details.

1) Basic floor to 1st floor -

Hence Minimum vertical reinforcement

AND)

i) Calculations of longitudinal reinforcement -

b) Shear calculation -

2) First floor to second floor -

i) Calculations of longitudinal reinforcement -

b) Shear calculation -

Note - The length of the boundary element decreases as it moves up. This means that stress is reduced.

3) Second floor to third floor -
i) Calculations of longitudinal reinforcement -

b) Shear calculation -

Result -

i) The shear wall is successfully designed.

ii) All inspections are carried out as per IS 13920 - 2016
