How to use steel structure correctly and rationally to prevent damage of steel structure workshop

We generally in the use of steel structure workshop for a long time, sometimes we will find that the whole phenomenon of damage is not this thing why, we should choose which methods to avoid this situation?

1. Insufficient structural bearing capacity is caused by load changes, extended service, and changes in specifications and procedures. Corrosion caused by chemical substances and electrochemical corrosion weaken the cross-section of steel structural members.

2, the component due to a variety of accidental deformation, distortion, disability, depression, etc., resulting in the weakening of the section of the component, the warping of the rod, connection cracking, etc. Under the action of temperature difference causes component or connection deformation, cracking and warping.

3. Others include mistakes in design, production and construction and illegal use and operation during service.

Measures:

1, section reinforcement method: in the local or along the length of the component with steel reinforcement, integrated into a whole so that the common force.

2, change the calculation diagram: add additional support, adjust the load distribution, reduce the level of internal force, the statically indeterminate structure bearing forced displacement, reduce the stress peak.

3, prestressed cable method: the use of high strength cable reinforcement structure weak link or improve the overall bearing capacity, stiffness and stability of the structure.

In the face of different use conditions in different environments, we should also follow the use rules, according to the use characteristics of the steel structure itself, to do a good job in the overall use of planning, do a good job in production.
