As a structure made of steel material, Foshan steel structure is composed of steel material, the steel structure is easy to corrode and the steel structure is refractory. So in the process of use, the steel structure is also damaged. There are many reasons for the damage of steel structure. For example, due to various unexpected deformation, distortion, disability and depression, the section of the member is weakened and the rod is warped. It can also be misoperated in the process of production or construction; it may also be corroded by other substances, and the repair methods of the damaged Foshan steel structure are:
1) the section reinforcement method is to reinforce the whole steel structure locally or along the whole length of the member, so as to make the whole joint force.
2) to change the calculation diagram: add additional support, adjust the load distribution, reduce the internal force level, make the forced displacement of the statically indeterminate structure bearing and reduce the peak stress.
3) the prestressed cable method: using high-strength cables to strengthen the weak links of structure or improve the overall bearing capacity, stiffness and stability of the structure.
Foshan steel damage, if not timely repair then the problem will become more and more large, so the problem must be repaired immediately, in order to reduce the risk to the lowest.
