Reinforcement Detailing of Beams from ETABS output

Objective of this challenge is to know the design of RC beam using Etabs, know the basics of beam reinforcement detailing with respect to primary standard, and to ensure the ductility reinforcement required by IS 13920-2016 satisfied in Etabs Design.

Procedure:

1) Open the attachment provided and opened in Etabs. Run the analysis after that click on the concrete design icon.

2) Here we have draw the detail of Grid A continious beam and Grid 3 continious beam.

3) After designing we can check the area for the reinforcement as top and bottom reinforcement in both left and right end.

4) We can also check the shear reinforcement from concrete design icon. and also check from the design report.

The reason for the failure of middle beam along grid A because the beam is overstressed. The torsional is also increased. The load has to be revised or reduced here.

As per IS 13920-2016

Vus=(0.87fy*Asv*d)/Sv

Here Fy=415kn/mmsq

Asy= 151mmsq

d=450mm

Sv=100mm

After calculating Vus=245Kn

Hence Ok
