In recent years, the aluminium architectures have been bringing new possibilities for building design and attracting attentions of not only the designers but also the building engineers together with the raising requirements toward realization of the sustainable society. Alminium structural elements have such extremely different characteristics that all of them are industrially produced through the extrusion process, which arc not the restrictions for design capability but the enhancements for extension of freedom for the variety of the design world. Present paper deals with the optimization of the cross section of alminium structural elements such as beams, columns and so on. Owing to the characteristics of Aluminium materials, precise optimization of the sections of them can bring out unexpectedly large advantage in its cost compared with the case of the steel elements. Primal-dual interior point method has been effectively utilized for solving the sequential quadratic programming problem which is raised by the single objective optimization problem subjected to the subsidiary conditions with equality as well as inequality equations.
