There are many reinforcement methods that can be used in structural reinforcement projects. Bonded steel reinforcement and carbon fiber reinforcement are two of them, and the two are often used for comparison. Because the calculation principles, formulas and limiting conditions of sticking steel and sticking carbon fiber reinforcement are the same. Therefore, after confirming that the components can be reinforced with bonded steel and bonded carbon fiber, how to quickly determine whether to use bonded steel or bonded carbon fiber cloth? Below, Horse will introduce how to choose bonded steel reinforcement or carbon fiber reinforcement.

(1) Structural deformation

The elastic modulus of carbon fiber cloth and steel plate is basically the same, but the tensile capacity of carbon fiber cloth is 8 times that of steel plate. Therefore, when the structure of the building is deformed greatly, it is recommended to adopt the reinforcement method of sticking carbon fiber cloth. If the deformation capacity is small and the bearing capacity of the building components differs greatly, in order to reduce the stress hysteresis and ensure the full performance of the material, the use of bonded steel reinforcement is preferred.

(2) Structural reinforcement requirements

In the case of the same structural reinforcement requirements, the cross-section required for the bonded steel reinforcement is relatively large, which significantly improves the structural rigidity. If the bending resistance of the two is the same, the deflection and crack width of the bonded steel reinforcement is smaller than that of the bonded carbon fiber cloth reinforcement.

(3) The impact of structural reinforcement on the environment

If the structure is in a humid corrosion reinforced environment, it is recommended to use carbon fiber cloth, because the corrosion resistance of carbon fiber cloth is much better than that of steel.

(4) Reinforced internal structure

If the internal structure of an existing building is too complex, in order to avoid damage to its internal structure during the reinforcement of the building, we can choose carbon fiber materials, which are convenient for cutting and suitable for a variety of operating environments.

(5) Reinforce the budget and make the final decision

If the construction budget is sufficient, both reinforcement methods are okay. If the construction budget is tight, a choice must be made. Bonded steel reinforcement and carbon fiber reinforcement. How different are the costs of different reinforcement methods? The use of carbon fiber reinforcement can effectively save construction costs. .

The above are the aspects that need to be considered in the comparison of bonded steel reinforcement and carbon fiber reinforcement. It is recommended that you choose the reinforcement method according to the actual situation when choosing between bonded steel reinforcement and carbon fiber reinforcement. This can not only ensure the practicability of the reinforcement method, but also save costs and shorten the construction period.
