Hainan Steel damage repair method

Although a longer service life of steel construction in Hainan, but steel is damaged, we find an immediate solution to immediate problems, steel grid describes the main factors that have damaged steel: 1 by load changes, extended service, specification change the structure and procedures leading to insufficient bearing capacity; 2, due to various accidents member deformed, twisted, disability, dents, etc., resulting in the member section weakened rod warping, cracking and other connections; 3, causing the connection member or under the effect of temperature difference deformation, cracking and warping; 4, due to erosion and chemical corrosion and electrochemical corrosion of steel resulting in the member section weakened; 5, the other including design, production, construction errors and improper use of the service period and other operations.

Hainan steel reinforcement technique there are three: 1, reinforced cross-section method: partial or full length along with steel reinforcement member, are integrally connected together so that the force; 2, change the calculation diagram: adding additional support, adjust the load distribution, reduce the level of the internal forces of statically indeterminate structure bearing for forced displacement, reduce peak stress; 3, prestressed cables: the use of high-strength structural weaknesses or cable reinforcement structure to improve the overall capacity, stiffness and stability degree.
