| Abstract: | The stability and nonlinear creep buckling of a compressed column with initial imperfection and torsion-al elastic restraint is studied by using sandwich model. The moment of endpoint, the deflection and creep equation of evolution are derived. The effect of the difference boundary conditions, initial imperfection and load on creep buckling are discussed. |

| Keywords: | column creep buckling torsional elastic restraint |
