Pre-engineered steel buildings are buildings made of steel structures and fabricated and installed according to pre-specified architectural and technical drawings. The process of making finished products (with a combination of inspection and quality control steps) goes through 3 main stages: Design, Fabrication of components, and Erection at the site. The entire steel structure can be produced synchronously and then delivered to the construction site in a relatively short time.
The architectural works that often use this type of house include factories, warehouses, galleries, supermarkets, commercial buildings, high-rise buildings, etc.
Steel structure load-bearing:
The frame load-bearing structure is a load-bearing system composed of a horizontal frame and a longitudinal connecting member, and the wall only serves as an enclosure. It is suitable for large spans, high plants, and large crane loads. The load-bearing framework is made of steel plate or hot-rolled steel through cutting and welding.
The horizontal framework of the factory building includes roof beams (or roof trusses), columns, and foundations. It bears the loads from skylights, roofs, walls, and other parts, as well as its weight, various loads generated by cranes, and longitudinal wall wind loads. These loads are transmitted to the foundation through the transverse framework through the columns.
The longitudinal connecting components are connected by the roof purlins, wall beams, tie rods, supports, etc. to the horizontal frame to form a single-story industrial building space system. They are mainly to ensure the stability of the transverse framework, bear the tension load, and transmit it to the foundation through the column.
