Cost is an important factor must being calculated in design of greenhouse structure. Reducing the quantity of steel used in structure is the most efficient way to cut down the cost of greenhouse. The principle of full stress optimization design was introduced. Based on mechanical analysis, the mathematical model of greenhouse structural optimization design was built. Full stress optimization was applied to multi span greenhouse design. As the aid of greenhouse design, software of optimization was developed. The software was tested in typical case and used to multi spans greenhouse.
