Reinforcement detailing of Columns from ETABS output
The ETABS file for a G+4 building is provided.
Run the analysis and design the RCC Moment Resisting Frame.
The following challenge deals specifically with two columns at the following grid intersections.
- 3A
- 3B
AIM-
- Provide details of longitudinal reinforcement
- for the two columns, from foundation to terrace level.
- Sketch the column cross sectional & elevation details
- or draft it using autocad software.
- Show shear reinforcement & lapping details as per special
- confining reinforcement provision of clause 8.1 of IS 13920 - 2016.
PROCEDURE-
Open etabs ,click concerete frame design tool.
-select display design info option .
-choose design output as longitudinal reinforcement.
-after selecting longitudinal reinforcement click elevation view .
-to avoid confusion click tick mark on ribbion and uncheck beam .
GRID A
1] for base to 1st floor maximum Ast = 7027
2]so we can provided 8 bar of 32 mm = 9x 803.84 =6446.72
2bars of 16mm =2x 200.96 =401.92
=7048.72 mm^2
there fore it can satisfy entire span.

there fore it can satisfy entire span.
GRID B ----
1.Base to tarrace maximum Ast = 5046
2.so we can provided 7 bars of 28mm
=7x615.44
3bars 20mm = 3x314
5250.8 mm^2
-therefore it can satisfy entire span.
Therefore it can be satisfied entire span.
SHEAR REINFORCEMENT ":
Click concerete frame design tool
choose shearreinforcing . click apply and ok.
-after selecting shear reinforcement option ,
the shear reinforcement values are obtained at each column .
