The selection of appropriate structural reinforcement materials requires consideration of the following factors:

Structural requirements: Understand the specific structural requirements for reinforcement, including increasing bearing capacity, increasing stiffness, and increasing seismic performance. Different reinforcement targets may require different types of materials.

Material performance: Evaluate whether the performance of the reinforcement material meets the requirements. Here are some common performance indicators:

1. Strength: Ensure that the reinforcement material has sufficient strength to withstand the loads applied to the structure.

2. Stiffness: Consider the stiffness of the reinforcement material to ensure that the structure can meet the design requirements after reinforcement.

3. Adhesion: The reinforcement material should have good adhesion and be able to firmly bond with the structural surface.

4. Durability: Consider the durability of reinforcement materials to resist erosion by moisture, chemicals, and environmental factors.

5. Alkali resistance: For the reinforcement of concrete structures, the reinforcement material should have good alkali resistance to prevent reaction with alkali in the concrete.

6. Seismic performance: If the goal of reinforcement is to improve the seismic performance of the structure, it is necessary to choose reinforcement materials with good seismic performance.

Construction conditions and methods: Consider the construction conditions and methods of reinforcement materials. Some reinforcement materials require specific construction techniques and conditions, such as specific temperature ranges, humidity requirements, or special construction tools.

Standards and specifications: Refer to applicable standards and specifications, such as ASTM, ACI, or national building standards, for regulations and recommendations on structural reinforcement materials.

Cost effectiveness: Considering the cost effectiveness of materials, that is, selecting economically reasonable reinforcement materials while meeting the requirements.
