Analysis & Design of RCC shear walls in the model using ETABS
AIM:
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.
PROCEDURE:
- first we open the file in ETABS
- we check for the error and analyse and Run the file
- Go to plan view ->open any floor plan level
- the image shown below is to show the shear wall 11A we have to work on
- chaneg the selection to all stories->sslect the 11A wall
- right click anywhere->show selected objects only (it'll only show the 11A wall)
- go to elevation->select 11
- now go to shear wall deisign section->start design check
- it'll check all the design and shows if any error are there
- Now Display->show tables->modal mass participation ratios
- to see the base reaction->display->show tables->base reaction
- now go to shear wall design->display design info
- show output->pier longitudnal reinforcing->the reinforcing info will be shown
- Now again go to display deisgn info->show output->pier shear reinforcing
- The shear values are all same in all floors
- Now display design info->deisgn output->Pier edge/boundary zone widths
- right clickmon the wall->a new sheet will open
- it shows the result values of the shear walls we deigned
BARS CALCULATION:
base floor to first floor:
reinforcement design of shear walls cross-section
- First floor to second floor
- second floor to terrace
