## Reinforcement of columns

Columns are the structural components that mainly ensure the required seismic performance of the building and the stirrups are the most critical components of the columns

## COLUMN 300 x 300 mm (with its entire length taken as a critical area)

In the second version of the column reinforcement the entire length of the column is considered as a critical area and Ø10 stirrups have been placed at a spacing of 100 mm. The column’s length is 2.70 m therefore, the provided stirrups are 27. This is presented as 27Ø10/100.
The stirrups placed in the joint area are Ø10/100, their total number is 5 and consequently, they are presented as 5Ø10/100.

## COLUMN 300 x 300 mm (with critical and non-critical areas)

In this first version of the column reinforcement, Ø10 stirrups, at a spacing of 150 mm, have been placed throughout the entire middle area of the column. That area’s length is 1.50 m and therefore the number of the provided stirrups is 10. This is presented as 10Ø10/150.
The stirrups placed in each of the column’s critical areas are Ø10/100, their total number is 6 and consequently they are presented as 6Ø10/100.The stirrups placed in the joint area are Ø10/100, their total number is 5 and therefore they are presented as 5Ø10/100.
