Reinforcement Detailing of Beams from ETABS output

AIM: 

To design the beams in detail from the Etabs 2018.  To provide details of longitudinal and shear reinforcement for the given two continuous beams      To calculate the value of maximum shear force in any one of the spans in the continuous beams.

PROCEDURE: 

Step:-1

• First we have to open the challange 7 page and download the challenge.
• After downloading the Challenge open it in the etabs 2018. 

Step:-2

• Next we have to check the load combinations, 

Step:-3

• Next we have to start the beam design by selecting the 'Start Design/Check' option 

Step:-4

• After the completion of the beam design, we need to select the 'Display Design Info' option
• After selecting the 'Display Design Info' option the new tab appears, In that we select the Longitudinal Reinforcing in the Design Output and click on the OK button 
• Next the longitudinal reinforcement details will appear, 

Step:-5

• Next we need to draw the Reinforcement diagram of 3 span continous beam along Grid-A, and also need to provide the reinforcement details.
• The maximum Ast for the bottom support is 1766mm^2and bottom middle is 702 mm^2
• The maximum Ast for the top support is 1889mm^2and top middle is 453 mm^2
• Now we provide 3-28Φat the top and bottom, as shown in the below figure.
• Next we provide 1-8Φat the top supports for the continuous beam,

Step:-6

• Next we need to draw the Reinforcement diagram of 7 span continous beam along Grid-3, and also need to provide the reinforcement details.
• The maximum Ast for the bottom support is 1061mm^2 and bottom middle is 1493 mm^2
• The maximum Ast for the top support is 1915mm^2 and top middle is 479 mm^2
• Now we provide 3-22Φ at the top and bottom, as shown in the below figure.
• Next we provide 1-10Φand 1-12Φat the top supports and we provide 2-16Φ at the bottom middle for the continuous beam 

Step:-7

• After providing the beam reinforcement details, we select the beam and right click on the beam then the new tab appears.
• Next we need to click on the Details option in Concrete beam design tab. 
• Next the Shear details will be visible, as shown below.
• As per the clause 6.3.3 the design force is 232 kN.
• We got, Maximum Shear force = 174.11 kN 

RESULT: 

The beams are designed successfully in detail from the Etabs software.

Provided the details of longitudinal and shear reinforcement for the two continuous beams.

And also calculated the value of maximum shear force in the continuous beams using the Etabs software .
