What is a steel structure, and what are its core load-bearing components?

    Core Load-Bearing Components:

1. Steel Columns
   • Primary vertical load-bearing members that support vertical loads (e.g., the weight of floors, roofs) and resist horizontal forces (e.g., wind, seismic activity). Common types include H-columns, box columns, and I-columns.
2. Steel Beams
   • Horizontal load-bearing members that transfer floor/roof loads to steel columns. They mainly bear bending and shear forces. Typical types are H-beams, I-beams, and box beams.
3. Steel Trusses
   • Framework structures composed of straight rods connected at joints (hinged or rigid). Rods mainly bear axial tension or compression, making them lightweight and efficient for large-span spaces (e.g., stadium roofs, factory workshops).
4. Steel Bracings
   • Anti-lateral force components that enhance the structure’s stiffness and stability, preventing deformation under wind or earthquakes. Common forms include diagonal bracings, cross bracings, and chevron bracings.
5. Connection Joints
   • The "links" between components (e.g., weld joints, high-strength bolted joints). They ensure force transfer between steel columns, beams, and trusses, and their reliability is critical to the overall safety of the structure.
