Reinforcement detailing of Columns from ETABS output

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 per the special confining reinforcement provision of clause 8.1 of IS 13920 - 2016.

Answer:-

Aim:- To design the given column reinforcement by using ETABS software

Procedure:-

• Run analysis for the given model
• Click on concrete frame design, find out the longitudinal reinforcement area, and take a screenshot of it.
• again, select the concrete frame design, go to display design info, find the shear reinforcement area, and take a screenshot.
• Select the story edit details to plot the reinforcement details

Step 1:

1) Open a G+4 Etab file
