摘要

Provided that there exist the power function relations between the cross sectional area, the axial moment of inertia and the section modulus for the beam section, this paper made it possible to use a maximum response ratio method for minimum weight design of a truss-beam mixed structure. An algorithm in which it is combined with the gradient projection method using information of sensitivity was made. Numerical solution result shows that it is possible to improve the accuracy of optimal solution.
