Strengthening and rehabilitation of RC beam and column

The reinforcement of 13.800M frame beam and continuous beam is strengthened by sticking carbon fiber reinforced polymer(CFRP） on the bottom of the original concrete beam.

Column Beam Strengthening

(1) the reinforcement of frame beams and continuous beams of 18.600M floors is reinforced by planting steel bars into existing concrete beams, and the cross sections of frame beams, continuous beams and new concrete beams are enlarged.

(2) the reinforcement of 13.800M frame beam and continuous beam is strengthened by sticking carbon fiber reinforced polymer(CFRP） on the bottom of the original concrete beam.

(3) the reinforcement of the 7.500M frame column is bonded with steel plate around the original frame column and reinforced by latex cement.

(4) the reinforcement of 7.500M frame beam and continuous beam is strengthened by sticking carbon fiber reinforced polymer(CFRP） on the bottom and side of the original concrete beam.
