The Structural Optimum Design of the Prestressed U-shell Flumes

The mathematical model of structural optimum design of the prestressed U-shell flumes is built.The theory and the construct application of the constrained nonlinear mixed discrete optimum design are introduced.A program of structural optimum design of the prestressed U-shell flumes is made.Comparing with the general design,a salient economic benefit can be obtained by using the optimum design of the prestressed U-shell flumes.
