The girders have cracks due to occasional factors, and their usability is not affected. But the safety level is low, the use of bonded steel plate reinforcement has fewer advantages, such as less engineering volume and relatively low cost.

Can steel plate be reinforced to repair cracks? Yes, Of course.

When we chooses steel plate reinfroced to repair crakcks? Horse Construction has summed up a few points for you.

1. The external appearance of the beam is not affected, and the cost of reinforcement is second, the method of steel plate strengthening should be used.

2. The girders have cracks due to occasional factors, and their usability is not affected. But the safety level is low, the use of bonded steel plate reinforcement has fewer advantages, such as less engineering volume and relatively low cost.

3. This method should not be adopted when the cross section of the beam is just low, and the cracks in the beam are widely distributed and the width is large.

4. In addition, the requirements of the strengthening standard, when the strength of concrete is lower than C15, this method shall not be adopted.
