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

• Open up the Model for which You Want to Design the Shear Wall

1. As we all know, the very first step is to locate the file on your computer and open the ETABS model.
2. And in our case, the file has been attached to the question.
3. So, download the file, save it at an appropriate location within your system, and then open the same using ETABS.

• Check the Model and Run the Analysis

1. Now that we have opened up the required model, we need to run the analysis using the software.
2. However, before running the analysis, we need to first check the model for any structural defects.
3. And to do that, simply drop down the analysis menu and click on the check option.
4. Select all the options given in the menu and then run the check.
5. Once the model has been checked and is free from errors, we can safely run the analysis.
6. And to run the analysis, simply press the F5 key on your keyboard or click on the play button available on the ETABS screen.

Classification of shear wall as per IS-13920-2016 clause 10.1.4 = Slender Wall

Minimum net vertical reinforcement as per IS-13920-2016 Table-1 = iii) 2363 mm2

Minimum vertical reinforcement within boundary element Table-1 = iii)

1440 mm2 on left (600 mm width boundary element

1080 mm2 on right (450 mm width boundary element

Minimum horizontal reinforcement in shear wall as IS-13920-2016 Table-1 (iii)

(Ph)min 0.0025 which is same 7500 mm2/m

Max. dia of rebar for shear wall as per IS-13920-2016 clause 10.1.8

1/10th of wall thickness = 300/10 = 30 mm

Commercial rebar dia 25mm shall be adopted.

Ash = 0.005 Sv h (fck/fy)

Sv = 150 mm, h= 1000 mm

Ash = 452 mm2
