Abstract
Optimal design of nonuniform, elastic, continuous columns with an unspecified number of available interior supports is considered. Subject to prescribed Euler buckling load, column length, and a prebuckling stress constraint, we detennine the optimal design and the optimal number and positions of interior supports in such a way as to minimize the total cost of column material and interior supports. Specific results are presented for columns with geometrically similar cross-sections.
