Philippine Oval Steel Truss Stadium Bleachers Canopy

This project is pipe truss oval bleachers in Semirara, the Philippines with an area of 2042m²， a width of 19.633m, and a length 104m.

This truss structure includes 21 primary trusses. Secondary truss, steel tie bar, column bracing, and horizontal bracing are used to connect the support and primary truss, column top below the truss. The roof purlin is a cold pressing rectangular steel tube, the roof cladding is an HYK anti-corrosion sheet.

The design use life for this pipe truss structure is 50 years, roofing cladding system use life is no less than 15 years. As this project is located near the sea, the wind force is heavier, and the corrosion of seawater is bigger, so this project needs to be maintained at a certain time（for example pipes made up by anti-rust paint, repairing destroyed roof panels on time, etc …）

The stadium bleachers canopy use a triangular cantilever truss structure, beautiful form, and clear force transmission; In order to meet the stress requirements, two steel pipes can be used for the lower chord and connected with a joint plate
