Reinforcement Detailing of Beams from ETABS output

Aim: To give the detailing of a beam in Etabs

Procedure:

• Open the downloaded file in Etabs

• Now check the model

• Now run analysis

• Now check the Design load combinations

• Now select start beam design or click shift+f6
• Now click on Display design info

• Now select the longitudinal reinforcement

• Now we get model as shown below

Reinforcement diagrams:

• Select the beam along the grid A
• Maximum Ast for the bottom support 1925 and bottom middle 789
• Maximum Ast for the top support 2045 and top middle 511
• Here provide the 3 bars of 20mm (942) and 5 bars of the 16mm (1004) at the bottom
• And provide the 4 bars of 20mm (1256) and 4 bars of 16 mm at the top (804)
• Next right click on the beam and check the sear details

• Select the beam along grid 3
• Maximum Ast for the bottom support 1042 and bottom middle 1501
• Maximum Ast for the top support 1940 and top middle 485
• Here provide the 2 bars of 12mm (226) and 4 bars of the 16mm (804) at bottom
• And provide the 3 bars of 20mm (942) and 5 bars of the 16mm (1004) at top
• Next right click on the beam and check the sear details

• From the Etabs results, we can observe that the shear demand is 378.9687KN
• So as per clause 6.3.3 provide 3 legged stirrups of diameter 10mm with spacing 95mm

Result:

The task of detailing the beam is done successfully
