Abstract
This paper aims to investigate the dynamicbuckling problems of linear beam system with initial axial forceand uniform moment by the developed spline finite elementmethod, which is employed to obtain the dynamic stiffnessmatrix. Second order effects of the axial force and moment areconsidered. The moment-frequency interaction diagrams inuniform axial force and moment are plotted. The effects ofwarping rigidity, torsional rigidity, axial tension andcompression on moment buckling are investigated in detail. Thespline finite element method is proved to be very efficient forthe present problems and many interaction diagrams can beplotted easily.
