1. Bolts in steel structure
In the steel structure, the bolt used is a bolt with high strength, and ordinary bolts cannot be used, because it has high strength requirements, and ordinary bolts are difficult to meet the requirements. Its strength requirements are generally above 8.8 level. Moreover, its own quality must also pass the line, because it will affect the overall quality of the steel structure. And its type, there are two kinds of torsional shear high-strength bolts and large hexagonal high-strength bolts.
2. The focus of steel structure design
The key points of steel structure design are:
(1) The stability of the steel structure mainly includes the stability of the overall structure and its local stability, so the design of the support and the structure can not be sloppy.
(2) The connection of steel structure is mainly three aspects: weld, bolt selection and joint structure.
