The anchoring adhesive is less than 80 C, and the high temperature produced in the welding is extremely unfavorable to the rebar adhesive, which usually directly affects the performance of the rebar adhesive and affects the anchorage and strengthening effect of the reinforcement.

Harmful cracks will not affect the bridge structure, affect the service life of bridges, accumulate over time, will lead to bridge collapse.

For cracks in concrete beams with width of 0.2-mm, besides epoxy resin pressure grouting according to the two methods, CFRP is bonded to seal the surface. Reinforced concrete beams are reinforced by CFRP sheets at the bottom of the mid span.

In order to study the effect of the external carbon fiber composite sheets on the shear strength of the specimens, the 12 specimens are rectangular beams with no abdominal reinforcement, and the bottom of the beam is matched with 2 18 longitudinal bars, and the size of the specimen is 2600 * 150 x 300.

Factors affecting the bearing capacity of beams strengthened with bonded steel plate: length of steel plate anchorage; historical loading; reinforcement ratio of steel bar; anchorage measures at the end of steel plate

The steel corrosion not only reduces the cross section of the steel, but also reduces the yield strength and the ultimate strength of the steel, which is one of the reasons for the reduction of the bearing capacity of the components.
