Client requirement
Strengthening design and construction addressed insufficient concrete strength in selected frame columns.
Engineering challenge
Member replacement redistributes forces. Composite action between new and existing concrete and the safety of adjacent members during construction required attention.
Technical approach
Site testing and structural analysis informed staged replacement. Unloading supports at connecting beams, stress-transfer techniques and precision force measurement supported construction control.
Project value
The project connects structural analysis, unloading support and process measurement when replacing load-bearing members in a high-rise building.
