Here, we present a novel two-step approach for optimum design of cellular truss-beams based on desired natural frequencies. The proposed approach at- tempts to decrease the design complexities, based on the so called Axiomatic Design, before any eort to solve the physical problem itself. It also serves as a generic approach which nds its generality through dimensional analysis with its accuracy from nite element analysis and its optimality from the fact that it remains true for all similar frameworks. The applicability as well as strength of the method is highlighted by some numerical examples.
