NEARLY OPTIMAL DESIGN OF TRUSSES

A.G.M. Michaell solved the following problem of structural optimization: given an equilibrium system of forces (loads and reactions), to design a plane truss with bars of a given elastic material in which the given forces produce axial stresses within a given allowable range, while the amount of material required for the bars is as small as possible. Michell's optimal structures, however, are not trusses in the customary sense of the term but trusslike continua with an infinity of joints. In this paper only trusses having the same number of joints are compared with each other, and the layout of a truss is discussed that requires an amount of material exceeding the minimum possible amount by at most a known percentage.
