Reinforcement detailing of Columns from ETABS output

Aim & Introduction :

Reinforcement detailing of columns in Etabs 2018.

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.

1. 3A
2. 3B

• 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 :

• From the existing drawing Choose the terrace level as shown
• Choose the required object and right click and choose display selected objects only as shown below it will appear
• Before Selecting It Choose as For All Storey
• Change it into 3D view as Shown below
• 
• By Selecting the Concrete Frame Iconw we may get the results for longitudinal reinforcement
• By geting it for both 3A and 3B go to elevation and select A and then 3 to get Simultaneously the results of longitudinal reinforcement as shown below
• 
• Similarly for getting shear reinfoecement choose concrete frame tool and selecr display option and change it as shear reinforcement the following representaion for shear reinforcement
• Total Height of the building Is shown as follows
• 
• shear reinforcement & lapping details as per special confining reinforcement provision of clause 8.1 of IS 13920 - 2016.
• 
• at the Beam Column junctions the shear reinforcement should be confined and placed at 100m spacing
• whereas at the centres minimun spacing for shear reinforcement should be 200mm

Result :

From the following procedure we came to know about the particular columns shear and longitudinal reinforcement and also how to place the shear reinforcement and lapping details
