The use of light portal frame system, the construction of light steel structure light weight, high strength, large-span, steel structure construction period short, lower investment costs, economic benefits. This design is to proceeds the building, construction design to the structural and actual engineering in light steel and calculation. The tractate includes internal force analyzes and combines, based on these analyses; can choose the section of beamand columniation. Next, checking computations of stability calculation of plane structure. The steel beam and column employs Q235 carbon structural steel. Connection bolts are high strength bolt of friction type with behavioral grade 10.9. Common bolts are rough type made by Q235B steel. Rod for manual welding usually adopts E43. Rigid connections apply to the column leg and the connection of column and beam adopts hinged connection. The metope and roofage adopts the double of the decked colored polystyrene clamps the circuit board. Otherwise, it is analyzed that the forced state of the bracing system for a steel factor building under wind load, the design of a bracing truss for a building with larger width. Avoid some errors in design of brace, tension rod, and tension rod joints. The design drawings are as follows plant floor plan, Node elevation profiles and detailed, Frame Construction ,wall-beam purlin plant layout map, construction of crane beam map, support layout map, foundation plan .
