Reinforcement Detailing of Beams from ETABS output

Aim - To run the analysis and design the RC moment resisting frame for the given ETABS Model

Procedure -

1. open the model in ETABS and check it from the Analyze tab

2. Check load combinations on the model

3. Start the beam design by selecting Start design/check option as shown

4. Select diplay design info option as shown

5. new tab will open with the following dialog box

6. Longitudnal reinforcement details have appeared

7. we must draw reinforcement diagram of 3 span continuous beam along grid A and also provide reinforcement details

max Ast for bottom support is 1766mm^2 and bottom middle is 702mm^2

for top - 1889mm^2 and top middle - 453mm^2

we will provide 3-28 dia bars at top and bottom

and 1-8 dia at top supports for continuous beam

8. reinforcement dia of 7span continuous beam along grid 3

the max Ast for bottom support is 1061mm^2 and middle bottom is 1493mm^2

max Ast for top support is 1915mm^2 and top middle is 479mm^2

we will provide 3-22 dia at top and bottom

and provide 1-10dia 1-12 dia supports and 2-16dia at the bottom middle for continuous beam

9. after providing reinforcement details, right click on beam and new tab appears

10. click on conrete beam design tab

shear details will be visible as shown below

as per clause 6.3.3 design force is 232 kN

max shear force we got is 174.11kN

result - beams are designed successfully in the software and longitudnal and shear reinforcement details have been provided.
