Structure Design

1、Design basic conditions

Dead load

The roof uses PVC membrane fabric, B1 fire resistance, 850g/m².The facade uses sandwich panels and glass walls.

Suspended Load

Each meter of the inclined beam of the rigid frame supports a suspended weight of 10kg. A suspension point is set every 5 meters, with the weight at a single suspension point not exceeding 50kg.

Wind Load

Wind gust of Beaufort scale 10, gust wind speed of 30 m/s, 108 km/h.

2、Basis of normative standards
