| Abstract: | Allowing for the influence of shearing stress and geometric stiffness matrix inducedd by damping on big constructions. It describes the dynamic stability under lengthway loads in detail and put forward the methods for calculating for calculating dynamic unstable sections and stimulating loads, combining the limited element with analytic method. A solution of dynamic stability is achieved by quadraic dynamic method. |
