What problems should be paid attention to in strengthening steel structure?

Steel structure reinforcement refers to the overall or local reinforcement with steel on the basis of the original building. The main reinforcement measures of steel structure include:

1、 Reduce the load and change the design drawing of steel structure;

2、 Increase the section and connection strength of the original structural members to prevent adverse factors such as connection crack propagation of steel structure. Other reinforcement methods can also be used, such as mature experience.

3、 For the steel structure engineering to be strengthened, it is generally divided into local reinforcement and overall reinforcement according to the degree of damage.

(1) Reinforcement of some steel structures refers to the reinforcement of members or connecting joints with weak bearing capacity. Steel structure factories mainly increase the section of members, reduce the free length of members, increase connecting joints and so on.

(2) The overall reinforcement of steel structure workshop refers to the reinforcement of the overall structure without changing the structural static calculation diagram, which is divided into the reinforcement method of changing the structural static calculation diagram.

(3) Steel structure processing to increase or strengthen the support system is also an effective method to strengthen the structural system.

(4) It is the most time-consuming and labor-consuming method to increase the section of the original member in steel structure engineering. Changing the schematic calculation method is the most effective, diverse and greatly reduces the cost.
