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
