Optimun Design of Trusses with Discrete Variables and Buckling Constraints

Juan H. Cassis, Abdón Sepúlveda


An efficient method to solve the least weight design of plane and space trusses is developed. A realistic truss model, including discrete variables and buckling constraints is used.
The solution is obtained solving a sequence of approximate problems in the dual space.
The difficulties introduced by the discrete variables and the buckling constrints are successfully overcome.
A couple of examples shows the effectiveness of the method.
