Reinforcing measures for steel structures

Release Time:

2021-09-15

When the steel structure is damaged, we need to find and solve the problem immediately. The main factors for the damage to the steel structure are: 1) Insufficient bearing capacity of the structure caused by load changes, extended service, and changes in codes and regulations; 2) The components are deformed, twisted, disabled, dented, etc. due to various accidents, resulting in weakened sections of components, warped rods, and cracked connections; 3) Deformation, cracking and warping of components or connections caused by temperature difference; 4) The cross-section of steel structural members is weakened due to corrosion caused by chemical corrosion and electrochemical corrosion; 5) Others include mistakes in design, production, construction, and illegal use and operation during the service period. There are mainly three types of reinforcement technical measures for steel structures: 1) Cross-section reinforcement method: Reinforce with steel in part or along the whole length of the member, and connect them into a whole to make them bear common force; 2) Change the calculation diagram: add additional supports, adjust the load distribution, reduce the level of internal force, force the displacement of the statically indeterminate structural supports, and reduce the stress peak; 3) Prestressed cable method: use high-strength cables to reinforce weak links in the structure or improve the overall bearing capacity, stiffness and stability of the structure.
