Prefabricated Steel Structure Gas Station Canopy Construction

1)The roof design of a large gas station, the roof of a gas station is a square pyramid flat space frame;

2)The span of the space frame is 54m × 54m, and the length-to-width ratio of the quadrangular pyramid flat space frame is 1:1;

3)The height-span ratio of the space frame is 1/12, and the number of short-span space frames is 9;

4)The included angle between adjacent members of the basic space frame unit is between 45° and 60°;

5)The space frame is supported by the lower support structure, the column spacing is 6m, and the nodes are rigid and fully restrained;

6)The rod material is Q235B steel, the elastic modulus is 210GPa, the Poisson’s ratio is 0.3, and the material density is 7.85g/cm3. The upper chord, lower chord, and we are all made of hollow steel pipes
