Descrição
A viga contínua com quatro vãos é carregada por forças axiais e de flexão (substituindo as imperfeições). All supports are fork - warping is free. Determine displacements uy and uz, moments My, Mz, Mω and MTpri and rotation φx. The verification example is based on the example introduced by Gensichen and Lumpe (see the reference).
