A problem dealing with the weight optimization of girders without transverse stiffeners is demonstrated. Constraints follow the 1978 AISC Specification. Actual programming is done in BASIC for an HP9830-A programmable desk calculator with a total amount of user memory of 3808 words (16 bits-two bytes per word). No analysis, but only synthesis, is performed. The theoretical proportions obtained do not necessarily conform to any particular set of available plate size, and may need adjustment to produce a practical design.
