Beam column bonded steel plate and FRP wrap

Some original frame columns are reinforced with the method of sticking carbon fiber(FRP) composite wrap (outside the beam and column node) and the pressure injection method of steel plate hoop and steel bar hoop (beam and column node area).

The following methods are adopted to reinforce the original components that are not required to meet the requirements of bearing capacity or do not meet the specifications after modification.


Some original frame columns are reinforced with the method of sticking carbon fiber(FRP) composite wrap (outside the beam and column node) and the pressure injection method of steel plate hoop and steel bar hoop (beam and column node area). 


For individual beams with insufficient bearing capacity of reinforced bars, bonded steel plate, bonded carbon fiber reinforced polymer (CFRP) wrap and enlarged cross-section method are adopted. 


The pressure glue injection method must be used in the construction of steel plate reinforcement.
