What are the principles of building reinforcement?

The division of the types of steel structure reinforcement on the industry, at present there are about more than ten kinds of strengthening methods, the current industry according to the steel structure reinforcement material of different reinforcement can be divided into the following types: were glued steel reinforcement, carbon fiber reinforcement, steel reinforcement, etc., situations of different means need to apply different reinforcement materials: For example, if the damage of the building is not particularly serious, it is generally used to strengthen the building. If it is the need for very urgent reinforcement, it is more appropriate to choose carbon fiber building reinforcement; Reinforcement method is also divided into: pressure grouting, outsourcing steel, crack repair, chemical grouting, prestress and other methods, and the effect of reinforcement also if the reasonable choice of the right reinforcement site to have the best performance, which is the need to have a very correct understanding. If you want to achieve efficient reinforcement effect, then you should choose the most appropriate method according to the site;

To fully understand the original structure and material of steel structure system: before the reinforcement scheme is determined must check and reliability evaluation of existing structure analysis, the existing structure of the material properties, structure and structural defects and damage of the structure and information structure, structure of the stress status and hold power levels to conduct a comprehensive understanding and analysis. The purpose of doing this is to avoid leaving hidden dangers or even engineering accidents in the building reinforcement project;

The steel structure scheme should be technically reliable, economical and reasonable, convenient for construction: before determining the scheme, we should refer to the actual situation of the existing structure, the stress characteristics of the reinforced structure, and analyze the structure as a whole, so as to ensure that the force transmission line of the reinforced structure system is clear and the reliability of the structure. Measures should be taken to ensure reliable connection. Construction but also the comprehensive economic indicators, considering the characteristics of building reinforcement construction, strengthening the construction of technical level, but also for these situations in construction reinforcement method in the design and construction organization, take effective measures, it can maximum reduce the use of the environment and the influence of adjacent building structure to shorten the construction cycle;

Reduce the damage to the original steel structure and try to use the bearing capacity of the original structure. Before determining the scheme, the existing structure or component should be preserved and utilized as much as possible on the basis of comprehensive understanding of the composition and bearing capacity of the structure after structural testing and reliability identification analysis. If a large number of the original structural components need to be removed, it may bring serious damage to the original structural parts retained, and it is more difficult to connect the old and new components in this way, which is neither economic nor may leave hidden dangers to the reinforced structure.

During the implementation of building reinforcement, the inspection of the actual structure should be strengthened and hidden dangers should be eliminated at any time. It is important to know that although we have carried out a comprehensive identification and detection of the existing structure before the determination of the reinforcement scheme, it is not excluded that the actual situation and structural damage and defects of the existing structure cannot be 100% mastered due to various objective reasons.
