What types of buildings should be reinforced promptly? Some old structures require seismic reinforcement, and in some countries, it's generally required for houses in earthquake-prone areas to undergo seismic identification and surveys. If the seismic identification results indicate insufficient seismic resistance, reinforcement must be carried out.
Masonry structure seismic reinforcement technology:
1. Reinforcement mortar and rebar mesh mortar surface reinforcement
Cement mortar and reinforced mesh mortar coating reinforcement is one of the more commonly used strengthening methods for brick-concrete structures. This method involves applying a certain thickness of cement mortar or reinforced mesh cement mortar coating to one or both sides of the brick wall to enhance its seismic resistance.
2. Reinforced concrete panel wall reinforcement
Reinforced concrete panel wall reinforcement is another commonly used method for reinforcing brick-and-concrete structures. This involves casting or spraying a certain thickness of reinforced concrete wall on one or both sides of the wall to be reinforced, to enhance the seismic bearing capacity of the original wall.
3. Add seismic-resistant wall reinforcement
Additional seismic walls for reinforcement are applicable when the overall seismic capacity of the building does not meet the assessment requirements, or when the spacing between seismic transverse walls exceeds the assessment requirements. The additional seismic walls can be either masonry walls or reinforced concrete walls, and it is generally preferred to use seismic walls made of the same materials as the original structure.
4. Additional Ring Beams - Reinforced Concrete Column Reinforcement
Ring beams and structural columns play a crucial role in enhancing the seismic resistance and preventing collapse of brick-and-concrete structures. Therefore, for brick-and-concrete buildings that have not been set up in accordance with seismic assessment requirements, reinforcement can be achieved by adding external ring beams and reinforced concrete columns.
5. Steel wire mesh - Reinforcement with polymer mortar coating
Steel wire mesh mesh - Reinforcement with polymer mortar surface is a method that uses steel wire mesh as the reinforcing material, bonding it to the wall surface with polymer mortar.

Seismic reinforcement design should also take into account the following issues:
The seismic reinforcement design must ensure uniform distribution of structural rigidity and strength, avoiding the formation of new weak layers.
2. When designing seismic reinforcement, vertical load-bearing components should be continuous to ensure a clear transmission path.
3. Increased seismic action due to changes in the structure's natural vibration characteristics after reinforcement.
4. When adding components or reinforcing existing ones in seismic reinforcement design, the potential for reducing the entire structure's torsional effect must be considered.
5. Reinforce seismic construction for vulnerable areas during seismic fortification design.
6. During seismic reinforcement design, ensure the structural load-bearing condition is more rational, prevent components from experiencing brittle failure, and eliminate load-bearing conditions that are detrimental to seismic resistance, such as strong beams with weak columns and strong members with weak joints.
7. When designing seismic reinforcement, consider the impact of the construction site. Based on the specific conditions of the site for the building, select a structural system with a smaller ground motion response after reinforcement, to avoid the increase in seismic effects exceeding the improvement in the structure's seismic capacity.
8. Utilize state-of-the-art earthquake resistance reinforcement techniques during design. Adopting relatively mature new technologies for earthquake reinforcement can significantly enhance the overall seismic performance of the structure and improve its resistance, which should be strongly promoted.

Advantages and characteristics of carbon fiber reinforcement methods include:
1. The material itself boasts high strength-to-weight ratio, and reinforcement does not alter the original structure's dimensions.
2. Simple process flow, short construction period, and high efficiency.
3. Reinforcement for concrete and steel structures is available, enhancing their load-bearing capacity, seismic resistance, and durability.
4. Operates normally in harsh environments.

How to formulate an anti-seismic reinforcement plan for buildings:
1. Measures to reinforce lateral force components such as seismic bracing frames, seismic walls, and supports using energy dissipation or isolation techniques. This serves to enhance the overall seismic performance of the structure and reduce the seismic response of stair components.
2. The one-way frame should be reinforced into a two-way frame, allowing for the addition of seismic walls and support structures to resist lateral forces.
3. When the requirements for single-span frame identification vary greatly, the spacing of seismic walls should not exceed 24 meters, and additional seismic walls, wing walls, supports, and other lateral force components should be added internally. It is also possible to change the corresponding axis single-span frame into a multi-span frame.
4. Insufficient building rigidity: In this case, there are two measures. One is to reinforce with additional reinforced concrete seismic walls or wing walls, and the other is to strengthen with additional supports for the seismic brackets.
5. In cases where the actual bending capacity of the frame beams and columns is insufficient, two measures are taken: one is to reinforce the frame columns by using encased steel sections, expanding the concrete cross-section, or bonding steel plates, etc.; the other is to determine countermeasures based on the results of structural elastic-plastic analysis under rare earthquakes.
6. When the reinforcement requirements for seismic support frame beams and columns do not meet the standards, the following methods can be adopted: using encased steel sections, increasing the concrete cross-section, or bonding steel plates, carbon fiber mats, steel wire mesh, and polymer mortar. These three methods can be employed.
7. If the frame column axial compression ratio does not meet the standards, reinforcement by expanding the concrete cross-section is sufficient.
8. When the reinforcement requirements of the reinforced concrete anti-seismic wall do not meet the standards, simply thicken the existing wall or add end columns and walls.
9. If the identification requirements of the stair components do not meet the standard, reinforcement can be achieved by using粘贴钢板, carbon fiber cloth, steel wire mesh, and polymer mortar.
