What are the reasons for the cracking of steel structural members?

The steel structure is mainly made of steel, which is welded by many steel members. Some improper operations during welding can cause cracks in steel components? When the steel construction is damaged, we need to solve it immediately after discovery. So, what are the reasons for the damage of steel structure members?

Reasons for cracking of steel structural members

One. Insufficient bearing capacity of steel structures caused by load changes, extension of service life, and changes in specifications.

Two. Steel members are deformed, twisted, failed, dented, etc. due to various accidents, resulting in weakened cross-sections of steel structural members, warped tie rods, and cracked joints.

Three. Deformation, cracking and warping of components or connections caused by temperature difference.

Four. The cross-section of steel structural members is weakened due to chemical corrosion and electrochemical corrosion.

Five. Other mistakes including design, production, construction, illegal use and operation during use.
