Single steel plant horizontal, vertical seismic calculation which way?

Single steel plant horizontal, vertical seismic calculation which way?

Hainan Steel plant lateral seismic accounting under normal circumstances, should be included in the roof space deformation analysis; use light roof, the plane can be bent frame accounting.
Plant longitudinal seismic accounting, the choice of the following options:
Lightweight wallboard or wallboard plant and a large column of flexible connection, according to the single particle accounting, each column columns earthquake should assign the following principles:
① reinforced concrete roof without purlins column column stiffness can share allocation;
② lightweight roof can withstand the share of pillar column gravity load representative value distribution;
③ reinforced concrete roof purlin desirable results above the average of the two distribution. Hainan Steel
