Seismic structure of the multilayer steel plant which measures?

Seismic structural steel plant in Hainan Steel multilayer What measures?
Steel framework supports the connection of multi-layer steel plant of high strength can be welded or bolted.
Plant support column between the longitudinal placement shall meet the following requirements:
Support should be set between the longitudinal column column column near the middle;
Support may be provided between the longitudinal column in the same bay, and down through the room with a pillar;
Between the roof and the top transverse horizontal support column support, should be provided in the same column between the ends of the plant unit; when the plant unit is long, between three to five column should be set together every.
Pin frame when each horizontal stiffness difference between the larger, when the vertical support without rules, shall request to set floor level support, its structure should meet the following requirements:
The level of support may be provided in the second bottom of the beam, but should also support rod end is connected to the floor longitudinal beam web and lower flange beams;
Floor level of support should be coordinated with the placement of the vertical support position;
Beam axis can be floor level as the chord support system, diagonals and chord angle between 30 ° ~ 60 °;
When the column grid mesh area within the secondary beam to accept large equipment load, should be added to the rigid tie rod, the earthquake reached the level of support equipment gravity chord nodes (beam axis), or. Hainan Steel
