Abstract
The derivations of the closed solutions for the natural frequencies of axially graded beam-columns on elastic foundation are discussed. Two cases of harmonically varying vibration modes are postulated and semi-inverse problems are also solved. The distribution of the flexural rigidity, material density and the variability of foundation coefficients are determined in terms of trignometric functions for solving the semi-inverse problems. The governing differential equations of the dynamic behavior of the beam on the elastic foundation are solved in a closed form for two sets of boundary conditions to the beams that include, a simply supported at one end and elastically guided at the other, and elastically guided at both its ends.
