This project is a steel structure gymnasium with two floors. The main structure is a portal-type steel frame structure with a length of 30m, a width of 20m and a cornice height of 6m. This design structure has the characteristics of economy, safety, and large use space. The selected materials have the properties of application, durability, lightness, economy, energy saving, recyclability, and environmental protection.
Roof dead load: 0.25KN/㎡; roof live load: 0.3 KN/㎡; wind load: 0.5 KN/㎡; snow load: 1.9 KN/㎡
