Seismic structure of multi-layer steel plant which measures
Steel framework supports the connection of multi-layer steel plant of high strength can be welded or bolted. Guangzhou Steel
Plant arranged between longitudinal column support should be consistent with 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, in accordance with Table 6.2.1 of the level of support required to set floors, its construction should fit the following rules:
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 arranged in coordination with the vertical support orientation;
Beam axis can be floor level as the chord support system, diagonals and chord angle between 30 ° ~ 60 °; Guangzhou Steel
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.
