High-precision welding and bolting technology ensures the overall quality and stability of the steel structure. This connection not only improves the safety of the building, but also shows the technological progress of steel structures in modern construction projects. In the "Research Progress of Key Technologies for Efficient bolting of Steel Structure", the development of unidirectional (side) high-strength bolt fasteners and the design method of semi-rigid steel frame with full bolting of beams and columns are introduced in detail. The application of these technologies effectively solves the connection problems of closed section members, and improves the fatigue life and maintenance cycle of the connection
. In addition, the stability design principles and key points of steel structures are also discussed in depth in the "Steel structure stability design Principles and key points", including stress design, anti-corrosion design and stability related design, which are key factors to ensure the long-term stable operation of steel structures.
