• Buckling and geometrical nonlinear beam-type analyses of timber structures 

      Eggen, Trond Even (Doktor ingeniøravhandling;2000:56, Doctoral thesis, 2000)
      An existing co-rotated formulation is presented, and a consistent nonlinear 3D beam element, based on 2nd order theory, and with internal geometric stiffness, is developed for implementation in the formulation. The element ...
