Beam in Oxz. Strong formulation, weak formulation, Hermite interpolation, Ke_ij, Fe_j, assembling and boundary condictions in w, in theta, in w'' and in w'''. Elastic supports. Example. Imposed displacement. Mixed finite element or Frame element in 2D. Independence of dofs between bar dofs and beam dofs. Inclinated mixed element and coordinate transformation matrix T. Obtaining Ke and Fe of a inclinated element (see pp277 and 278 in the book).Obs1: Theoretical part is finished.
Obs2: O&A observation.
