The Specification Of Portal Steel Frame Buildings Portal Steel Frame Buildings is the most common structure system. It widely used in light steel buildings such as warehouses, workshops, sheds, garages. Compared with the reinforced concrete structure. The portal steel frame has the advantages of a lightweight, high rigidity, flexible design, reasonable force, and convenient construction.
The composition of Portal Steel Frame Buildings 1. Primary framing: transverse rigid frames (including middle and end rigid framing), floor beams, crane beams, support systems, etc. 2. Secondary framing: roof purlin and wall girt, etc. 3. Envelope structure: roof and wall panels; 4. Auxiliary structures: stairs, platforms, handrails, etc .; 5. Foundation.
Steel columns, roof beams, and bracing systems constitute the primary force skeleton of the portal steel frame. It is the primary framing. Roof purlins and wall girt not only support the roof and walls but also provide lateral support for the main structural beams and columns, which form the secondary framing of portal steel frame buildings. The roof and wall panel serves as envelope and closure of the entire structure, while also increasing the overall stiffness of the steel buildings.
