RC column removal instrumentation and monitoring

RC column removal from a newly constructed villa, Phuket-Thailand

The RC column below was requested to be removed by the owner of the villa to enlarge the middle room area of the floor level LG. Before column removal, steel beams and columns additional structure were fabricated and erected to support existing RC structure. To maintain and monitor the structural serviceability and stability due to the column removal, displacement transducers were implemented at several locations over several floor levels of the building during column removal, and member displacement was monitored in real time via a dynamic data logging system and comparison with ACI deflection limits was carried out during column cutting.
