Specifications for Ordinary Bolt Connections in Steel Structures

1. The connection strength of ordinary bolt connections in steel structures is determined through calculations performed by structural engineers based on design requirements. This involves comprehensive consideration of factors such as bolt diameter, length, quantity, as well as the dimensions and material properties of the connected members.

2. While standard bolts provide some preload, high-strength bolts may be selected in certain applications—particularly those subject to heavy loads or harsh environments—to ensure connection stability and load-bearing capacity.

3. During construction, strict adherence to specifications is mandatory. This includes selecting appropriate bolt types, applying correct tightening torques, performing necessary corrosion protection, and inspecting connection points for defects or damage.

4. To ensure the safety and reliability of ordinary bolted connections in steel structures, reinforcement measures are typically employed, such as adding washers or welding stiffeners, along with regular maintenance inspections.

5. Ordinary bolted connections generally provide good seismic performance under normal conditions. However, under extreme conditions like intense vibration or impact, loosening or even failure may occur. For such applications, additional anti-vibration or impact-resistant measures may be required to enhance safety.
