Main Components of Long Span Steel Construction

Long span steel construction involves various components that work together to create expansive, open spaces without the need for intermediate supports or columns. Here’s an introduction to the key components:

  • Main Structural Members: The main structural members form the framework of the long span steel structure and provide support for the roof and floor loads. These members typically include long span steel beams, girders, and long span steel trusses, which are fabricated from high-strength steel sections such as I-beams, H-columns, or box girders. These members are designed to withstand the applied loads and distribute them efficiently across the structure.

  • Roof System: The long span steel structure roof system comprises the roofing material, long span roof trusses or beams, purlins, and other components that support and protect the building’s interior from weather elements. Long span roof trusses or beams span the distance between the main structural members, providing support for the roof covering.
  • Floor System: The floor system includes the structural elements and materials that support the building’s floors and provide a stable platform for occupants and equipment. This may include steel beams, joists, and decking, as well as concrete slabs or composite floor systems. The floor system is designed to withstand the imposed loads and provide adequate support for various uses within the building.
  • Columns and Supports: Large span steel structures may require columns or supports at the building’s perimeter or at specific intervals to provide additional stability and resist lateral forces such as wind or seismic loads. These columns are typically made of steel sections and are designed to transfer vertical loads from the roof and floor systems to the foundation.
