Design of Tubular Truss Combined with Photovoltaics

The design of tubular trusses combined with photovoltaics needs to consider both structural strength and power generation efficiency. The truss main body is constructed with Q355E high-strength steel pipes (such as ∅159x5~6), and connected by intersecting weld nodes to ensure the stability of the 35m×60m large-span platform.

A truss inclination angle of 15° optimizes light reception, while purlin installation positions are reserved to achieve an integrated design of components and structure.

Wind resistance and terrain adaptability are key. Drawing on flexible support tensioned prestressing technology, spatial cable nets are used to enhance wind resistance in typhoon-prone areas (such as Dingan, Hainan). For desert or mountainous projects, segmented trusses (each section ≤12m) and cambered designs (1/500 deflection) are used to cope with complex terrain, taking into account both construction convenience and structural safety.
