What are the common reinforcement methods of steel structure workshop?

Steel structure workshop is in the construction of application is extensive, and the strength and durability are the characteristic of it, but in order to better ensure that the steel structure itself durable sex, are in the process of installation of steel structure reinforcement, several common reinforcement methods at present mainly include:

Steel structure engineering manufacturer

1, prestressed cable method: this reinforcement method is mainly the use of high strength cable reinforcement structure weak link or improve the overall bearing capacity, stiffness and stability of the structure;

2. Remove the parts that need reinforcement or updating from the original structure: When the original structure is seriously damaged or the original section bearing capacity is too small, it must be strengthened or updated on the ground, it must be set up temporary support, so that the replaced components can be completely unloaded, at the same time, it must ensure the safety of the entire structure after the unloaded structure;

3, change the calculation diagram: add additional support, and then adjust the distribution of load, reduce the overall level of internal force, the statically indeterminate structure bearing force only, so as to reduce the stress peak;

4, unloading reinforcement: this major is suitable for application in structural damage is larger or the parts as well as the connection of the stress state is very high, need to temporarily reduce will load, the structure of some main under moving load (such as crane beam, etc.), can limit the moving load, which is equivalent to most of the unloading.
