Analysis & Design of RCC shear walls in the model using ETABS
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.
Aim: To analyze the given G+6 building and to provide details of longitudinal steel ratio, boundary element length ans shear reinforcing ratio of shear wall of size 300x1500 at grid A-11. To also provide elvation drawing of reinforcement details of the shear wall from base to terrace.
Procedure:
1. Open given G+6 building and run the analysis.
2. Choose the required sgear wall at grid A-11 and hide the remaining elements
3. Go to shear wall design and display design info, choose peir longitudinal and peir shear reinforcing and peir edge/boundary zone width to get the results.
4. The Peir Longitudinal Reinforcement for grid A-11 shear wall
5. The Peir Shear Reinforcement for grid A-11 shear wall
6. The Peir Edge/Boundary zone width for grid A-11 shear wall
7. Now need to calculate the minimum vertical and horizontal reinforcement in web and boundary elements using IS 13920 code
8. Calculate the area of reinforcement using minimum reinforcement value as shown below
9. Note down the boundary element lenght from ETABS.
10. All calculations are done as per code IS 13920 - 2016
Result: Analyzed the given G+6 building and provided the details of longitudinal steel ratio, boundary element length ans shear reinforcing ratio of shear wall of size 300x1500 at grid A-11. Also provided elvation drawing of reinforcement details of the shear wall from base to terrace.
