FIELD: construction, particularly to strengthen load-bearing reinforced concrete structures damaged by fire.
SUBSTANCE: method involves strengthening support devices made as two pressing cases tightly arranged on load-bearing member to be reinforced to provide 2-3 fold static rest support cases friction coefficient increase; installing reinforcing struts with pre-stressing thereof, wherein the reinforcing struts unload damaged member zone along with compression force control; bringing reinforcing struts into joint action with damaged load-bearing structure members without unloading thereof.
EFFECT: increased efficiency of compressed reinforced concrete member quality recovery in wakened load-bearing structure zone and increased reliability and rate of bringing pre-stressing struts into joint action for compressed member reinforcing.
