  • A closed form solution of the dynamic stability problem of a beam-column system with hinged ends loaded by an axial periodically time varying compressive force of an elliptic type was presented.Solution of the governing equation was obtained in the form of Fourier sine series and the resulting ordinary differential equation was solved analytically.Finding the exact analytical solutions of the dynamic buckling problems were difficult.However, availability of exact solutions provided adequate understanding about the physical characteristics of the system.The frequency-response characteristics of the system, the effects of static load, driving forces and frequency ratio on the critical buckling load were also investigated.
