PPrabhat Tiwari17 Sept 2024

OBJECTIVE -

To know the design of RC shear wall using ETABS analysis

To know the basic of Shear wall reinforcement detailing with respect to primary standards

To ensure the ductility reinforcement required by IS 13920- 2016 been satisfied in reinforcement drawing

QUESTION -

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 run the analysis and design the RCC shear wall shown in the ETABS model

PROCEDURE :

Open the ETABS file Lecture9_challenge.
After opening the file the first step is to Run analyze.

Select the shear wall of size 300x1500 at grid A-11 in the structural model.
Right click mouse on the selected shear wall at grid A -11.
Select option show only selected.

Now we will design the selected shear wall.
Click on Shear Wall design

After completion of designing process in the ETABS software, we need to collect the all required data which will be helpful in the further detailing calculations.
So in order to design the shear wall we need three main data
Longitudinal Reinforcement
Shear Reinforcement
Boundary Element Width (BE)
