What are the advantages of building steel structure reinforcement

I. There are three main technical measures for steel structure reinforcement

1. Section reinforcement method: local or along the component with reinforcement, connected into a whole, so that the common force.

2. Prestressed cable method: high strength cable is used to strengthen the weak link of the structure or to improve the overall bearing capacity, stiffness and stability of the structure.

3. Change the calculation diagram: add additional support, adjust the load distribution, reduce the internal force level, force the statically indeterminate structure support displacement, reduce the peak stress.

II. Advantages of building steel structure reinforcement and storey adding project:

1. The house can be renewed and the appearance of the city can be improved through readjustment.

2. The original foundation and materials can be used, and the project cost is low.

3. It can improve the land utilization rate and reduce the cost of household relocation.

4. Reduce site excavation, stacking, transportation and handling of building materials.

5. The use of structural transformation and storey adding transformation can not only expand the use area of the building, but also alleviate the housing shortage.

6. By adding ring beam, structural column, inner and outer column and other reinforcement methods, the seismic capacity and stress of the building are improved, and the service life of the building is extended.

7. In the reconstruction of the original building structure, the use of the original building will not be stopped (only partial use will be stopped), and the work and life will not be affected.

8. It can make full use of the foundation bearing capacity of the existing buildings due to long-term load, the safety reserve of the foundation in the design of the existing buildings, or the favorable conditions for improving the foundation bearing capacity due to the decline of the groundwater level. It is the most economical to directly carry out the storey adding reconstruction project without foundation treatment or with a little foundation treatment.

Steel structure reinforcement project mainly uses steel, steel strength is high, elastic modulus is high. Compared with concrete and wood, it has lower density and yield strength. Therefore, under the same stress conditions, the steel structure section is small, light and convenient for transportation and installation.
