| Abstract: | This paper considers optimal design of the trusses structure with strength,deflection,Stiffness and buckling constraints.Objective function is minimum weight of structures.The structure supports heavy load and has large span.The shape of structure section is shape I or compound shape I.The paper mainly discusses how to treat buckling and stiffness constraints.The result of the example indicates that the method is reasonable. |
