Column failure at Anand Kunj
Column failure at Anand Kunj
Problem :
- Additional load due to internal change in use of area on upper floors resulted in sudden failure of a column on ground floor level
Solution :
- The column was temporarily relived of load by supporting beams with multiple steel props
- The concrete that was crushed was removed and steel was treated with anticorrosive agent
- Additional rebars were added along with stirrups and the column was re-casted using micro-concrete to achieve high early strength
- Column was wrapped with double layer of GFRP wraps and plastered
