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:

      1) To run the Analysis and Design the RCC Shear Wall

      2) To extract values of Longitudinal Steel Ratio, Boundary Element Length and Shear Reinforcement ratio from Design results.

      3) To provide cross sectional steel arrangement of the shear wall from its base up to terrace, in compliance with provisions of IS 13920 – 2016.

      4) To provide elevation drawings of the reinforcement details of the shear wall from base up to terrace

 

PROCEDURE:       

         STEP : 1 Open File:-  

               - Initially open the given ETABS file.

               -  Download the file given in the attachment then start the ETABS 2017 software 

          

         STEP: 2 Check the piler lables:-  

                   - Click on Right click - go to other asignments

                   - Check box of lables in pier assignments

                      

                          

                      -  Check the pier lables are right or wrong

                       

         STEP: 3 Check model errors:- 

                    - Check for errors was done next by selecting Check Model under Analysis menu.

                                              

                                                                            

 

 

         STEP:4 Check revise preference :-        

                    -  Click on shear wall design - select view revise prefernece

                                                                                     

 

                    -   Make changes if required - click on ok

 

                                      

   

         STEP: 5 Run analysis:- 

                    - Then go to elevation and select 11 - apply - close then

                   -  Click on Analyse tab and select Run Analysis to perform the analysis function.

         STEP: 6 Run analysis of shear wall:-

                 - go to 3D - then Click on shear wall design logo

 

                                            

                 -  wait for process

 

 

 

         STEP: 7 Show wall design:- 

                 - To view the selected design results Click on Design followed by Shear Wall Design and then select Display Design info.

                                    

                 -  Now from the dialogue box which appears select the required ones like Pier Longitudinal Ratio, Pier Reinforcement Ratio, Pier Shear Reinforcement and Pear Edge/ Boundary Zone Width.

                   1) Pier Longitudinal Ratios:

                                             

                                                                   

 

                                    

 

 

 

 

                                    2) Pier Reinforcement Ratio:

                                          

                                                       

                                                     

 

 

 

 

                                   3) Pier Edge/ Boundary Zone Width:

                                                                

 

                                                             

 

                                                             

 

 

 

 

 

                                   4) Pier Shear Reinforcement:

                                                             

 

                                                             

 

                                                             

              Step:8 - Shear wall detailing calculation: 

                                           

                                          

                                          

                                          

                                          

                                          

                                          

                                          

 

                                                                                

RESULTS:

1. Analysis was performed and RCC Shear Wall was designed sucessfully.
2. Extracted values of Longitudinal Steel Ratio, Boundary Element Length and Shear Reinforcement ratio from Design results.
3. Provided cross sectional steel arrangement of the shear wall from its base up to terrace, in compliance with provisions of IS 13920 – 2016.
