Carbon Fiber Strengthening Apartment

Reason: They drilled holes in the apartment beams and cut steel.

Problem: The cross-sectional area of the beams was reduced after drilling and cutting, and the load-bearing capacity decreased.

Solution: They used carbon fiber to replace the lost steel. Carbon fiber plate bonding on the bottom of the beams, then wrap carbon fiber for shear strengthening.
Carbon fiber has a high strength-to-weight ratio and can be several times stronger than steel. Using carbon fiber to replace the lost steel section can effectively restore or even increase the load-bearing capacity of the beam.
