What aspects should be paid attention to when strengthening steel structures?

Steel structure reinforcement refers to the use of steel as a whole or as a local reinforcement on the original building foundation. The main measures for strengthening steel structures include:

1、 Reduce load and change steel structure design drawings;

2、 Increase the cross-section and connection strength of the original structural components to prevent adverse factors such as crack propagation in steel structure connections. Other reinforcement methods can also be used, if there is mature experience.

3、 The steel Structural engineering to be strengthened is generally divided into local reinforcement and overall reinforcement according to the degree of damage.

(1) Partial steel structure reinforcement refers to the reinforcement of members or connection nodes with weak load-bearing capacity. Steel structure factories mainly use methods such as increasing the section of members, reducing the free length of members, and increasing connection nodes.

(2) The overall reinforcement of steel structure factory buildings refers to the reinforcement of the overall structure without changing the structural static calculation diagram, and is divided into reinforcement methods that change the structural static calculation diagram.

(3) Adding or strengthening support systems during steel structure processing is also an effective method for strengthening structural systems.

(4) The most time-consuming and labor-intensive reinforcement method for steel Structural engineering is to increase the section of the o
