Reinforcement Detailing of Beams from ETABS output

• AIM: To provide details of longitudnal and shear reinforcement for the two continous beams usinf ETABS

• PROCEDURE:

STEP 1):

• After downloading the model given in the question ,click the concreter frame design tool in the ribbon tab
• Choose the appropriate design combination
• Select the appropriate combination from the dialog box
• CLick OK

STEP 2)

• Once the analysis is done ,click frame icon
• After clicking the icon ,it starts checking the concrete design

STEP:3)

• After the checking is done ,go to the plan view
• On the plan view we have a column and beam detailing
• For this gridd 3 and grid A need to provide reinforcement details

STEP 4:)

AT TOP

• Maximum Ast support =2045
• Maximum Ast at middle=485
• 2 dia of 32 mm= 1606
• 1 dia of 25 mm= 490

To satisfy the support we need to provide 2 dia of 32mm bar and additionally in the middle need to provide 1 dia of 25mm

AT BOTTOM

• Maximum Ast at support=1056
• Maximum Ast at middle=1501

• 3 dia of 25 mm =1470
• 1 dia of 16mm=200.96

To satisfy the support we need to provide 3 dia of 25 mm bar and additionally in the middle of need to provide 1 dia of 16mm

STEP 5)

GRID A:

• Maximum Ast at support=1927
• Maximum Ast at middle=789
• 2 dia of 32mm
• 1 dia of 16mm

To satisfy the support we need to provide 2 dia of 32mm bar and additionally in the middle need to provide 1 dia of 16mm

STEP 6:)

• Right click the grid A beam
• Click detailas and switch it into shear details

STEP 7:)

• As per clause 6.3.3 the design force of equivalent Ve=242.75kn
• Shear force under the linear analysis as per load combination of UDCCons66=194.825
