Influence of Different Earthquake Excitations on Dynamic Stability of Single-Story Steel Frame

Article Preview

Abstract:

Dynamic stability analysis of twelve single-story steel frame structures is analyzed based upon the finite element method. The influence of different earthquake excitations on dynamic stability of single-story frame is studied. Time history curves of displacement, hysteretic curves of restoring force, phase plane trajectory curves have been obtained. The results indicate that the ultimate displacements of frames when structures collapse are almost identical and ultimate displacements are independent of earthquake excitations.
