Technical measures for steel structure reinforcement

When steel structures are also damaged, we need to immediately detect and solve the problem. The main factors causing damage to steel structures 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.
