Technical measures for steel structure reinforcement

When steel structures are also damaged, we need to immediately detect and solve the problem. Steel Structure Network introduces that the main factors causing steel structure damage are:

1) Insufficient structural bearing capacity due to load changes, expired service, and changes in specifications and regulations;

2) Due to various unexpected deformations, twists, disabilities, dents, etc., the cross-section of the component is weakened, the members are warped, and the connections are cracked;

3) Deformation, cracking, and warping of components or connections caused by temperature differences;

4) Corrosion caused by chemical substances and electrochemical corrosion leading to weakened cross-sections of steel structural components;

5) Other issues include errors in design, production, and construction, as well as unauthorized use and operation during service life.

There are three main reinforcement techniques for steel structures:

1) Sectional reinforcement method: Steel reinforcement is used locally or along the entire length of the component to connect it as a whole and exert joint force;

2) Change the calculation diagram: add additional supports, adjust load distribution, reduce internal force levels, force displacement of statically indeterminate structural supports, and reduce stress peaks;

3) Pre stressing cable method: using high-strength cables to reinforce weak links in the structure or improve the overall bearing capacity, stiffness, and stability of the structure.
