The sag rod in steel structure is a member that connects and reinforces the steel structure. It is usually made of high-strength steel and has the ability to withstand large tensile forces and pressures.

what's the purpose of sag rod in steel structure building?

1. Withstand tensile force: Tie bars can withstand the tensile force generated by external loads in the steel structure, ensuring that the whole structure can still maintain stability and safety when subjected to external forces.
2. Load sharing: The design of tie bars makes it possible to effectively spread the load to other structural components, thus reducing the burden of other components and enhancing the bearing capacity of the whole structure.
3. Connecting members: Tie bars as an important element to connect different structural members, enhance the integrity of the structure, and prevent displacement or deformation between members.
4. Seismic performance: In the event of natural disasters such as earthquakes, the tie bar reduces the vibration and deformation of the structure by transmitting and dispersing the seismic force, thus enhancing the seismic capacity of the structure.
