Class of construction: Durable grade Ⅱ,fire protection rating Ⅱ,earthquake intensity 7 degrees. The workshop adopts portal frame while the proof of the building adopts the 75 thick EPS sandwich board and the purline use crimping tank-type purline, both the beam and column use the H section steel. The base is a single base under the column. This design is to proceeds the building construction design to the structural and actual engineering in light steel and calculation. The tractate includes the internal force analyzes and combines, based on these analyse, we can choose the section of beam and columniation. Next, checking computations of stability calculation of the plane structure. The steel beam and column employs Q345 carbon structural steel. Connection bolts are high strenth bolt of friction type with behavoure grade 10.9. Rod for mannual welding usually adopts E43. rigid connection apply to the column leg and the connection of column and beam adopts hinged connection.
