What issues should be paid attention to when reinforcing steel structures?
2025-05-07
Steel structure reinforcement refers to the use of steel to strengthen the original building as a whole or in part. The main measures for strengthening steel structures are:
1. Reduce the load and change the steel structure design drawings;
2. Increase the cross-section and connection strength of the original structural components to prevent the occurrence of unfavorable factors such as the expansion of steel structure connection cracks. Other reinforcement methods can also be used if there is mature experience.
3. For steel structure projects that need to be reinforced, they are generally divided into local reinforcement and overall reinforcement according to the degree of damage.
(1) Partial steel structure reinforcement refers to the reinforcement of rods or connection nodes with weak bearing capacity. The main methods of steel structure factories are to increase the cross-section of rods, reduce the free length of rods, and increase connection nodes.
(2) Overall reinforcement of steel structure workshops refers to the reinforcement of the entire structure without changing the structural static calculation diagram, and it is divided into reinforcement methods that change the structural static calculation diagram.
(3) Adding or strengthening the support system during steel structure processing is also an effective method to strengthen the structural system.
(4) The most time-consuming and labor-intensive method of strengthening steel structure projects is to increase the cross-section of the original components. Changing the schematic calculation method is the most effective method, and it has various forms and can significantly reduce costs.
