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

Aim:

• To run the analysis and design the RCC shear walls shown in the ETABS model.
• To Extract values of longitudinal steel ratio, boundary element length and shear reinforcing ratio from the design results.
• To tProvide cross sectional steel arrangement of the shear wall from its base up to terrace.
• Using AutoCAD application for this exercise or Alternatively, it can be drawn by hand as well.
• To provide elevation drawings of the reinforcement details of the shear wall from base up to terrace.

INTRODUCTION:

• Shear walls are vertical elements of the horizontal force resisting system.
• They are constructed to counter the effects of lateral load acting on a structure.
• When shear walls are designed and constructed properly, and they will have the strength and stiffness to resist the horizontal forces.
• Shear walls are especially important in high-rise buildings subjected to lateral wind and seismic forces.

Step 1:

1) Open the ETABS file

2) After the analysis click Concrete frame design

Step 2:

1) Need to check there is any failures occurs

2) Click Shear wall design tool

3) select Display info and choose PM failure

Step 3:

1) Click any wall and check the details

2) Here there is no failure occurs all the values of reinforcement ratio is within 4%

Step 4:

Shear Reinforcing

1) Go to concrete frame design

2) Click Display design info

3) Choose Shear reinforcing

Step 5:

Boundary element width

1) Go to concrete frame design

2) Click Display design info

3) Choose Pier edge or boundary zone width

Step 6:

Longitudinal Reinforcement:

1) Go to concrete frame design

2) Click Display design info

3) Choose Pier longitudinal reinforcing
