Abstract
Natural frequencies of a bending beam subjected to an axial force vary from the ones without the axial force. A compressive axial force exceeding a critical value leads the beam to a buckling. It is important to consider the effect of the axial force in truss and cable structures. The authors presented the Transfer Influence Coefficient Method, an advantageous method for dynamic response of structures but it didn't take the axial force into account for the bending motion. In this paper, a new algorithm of the Transfer Influence Coefficient Method to involve the effect of the axial forces is presented. Variation of natural frequencies according to axial forces and a buckling load of a beam structure are estimated by the newly presented algorithm.
