We were hamstrung with a maximum 50mm increase allowance in sections of junctions, but the results were exemplary.
THE CHALLENGE :
- Faulty construction practices had led to slippage in the joints and junctions of flared and vertical columns.
THE ODDS :
- The structure was slated to be cladded, which restricted the increase in sections of the junctions by only 50mm on all sides.
OUR RESPONSE :
- Initial assessments of the structure were carried out to check for consequential damages, if any
- We then designed a retrofit scheme for both the flared and vertical column junctions
- We used Steel-plate jacketing while anchoring it to parent concrete with shear connectors and micro-concreting, to reinforce all junctions externally
- As a result, the load transfer was rerouted from concrete to steel jacket and steel jacket to concrete, balancing it completely and effectively
