| Abstract: | In this paper, the state of the art and existing criteria of dynamic stability in the field of structural engineering are reviewed, and then new methods and criteria for judging dynamic stability of lattice steel structures with strong geometrical nonlinearity under any dynamic loading (such as seismic loading etc.) are proposed. Finally the proposed criteria are demonstrated in examples of dynamic stability analysis. |
