A procedure and related theories are developed to find the loci of optimal support positions for a structure to maximize its fundamental eigenvalue by increasing the support stiffness. The concept of limit eigenvalue, which is the upper bound of fundamental eigenvalue achieved by adding supports, is

## Abstract In this paper, the position optimization of simple supports is implemented to maximize the fundamental frequency of a beam or plate structure. Both elastic and rigid supports are taken into account. First, the frequency sensitivity with respect to the movement of a simple support is der
