FIELD: construction, particularly to recover compressed reinforced concrete structures damaged by fire, explosion or other accidents.
SUBSTANCE: method involves inspecting the column; performing verifying strength analysis of damaged column and recovery members; installing thrust seat pressed with normal force of support bearer and pre-stressed strut with force control; applying fire-proofing covering on steel column recovery members.
EFFECT: increased efficiency of damaged column inspection and column condition estimation, as well as increased reliability of bringing pre-stressed strut and damaged structures into joint action.
