| Abstract: | Optimization design of prestressed steel trusses not only includes the optimization of sectional dimension of the bar but also the optimization of the different schemes of steel cables and the different pretensions of steel cables. In this paper, the targt function is the cost of prestressed steel trusses. The analysis of an example proves that the economic benefit of the optimization design is evident and the optimization design is significant in engineering design. |
