FEM stiffness matrix for simple frame exploiting symmetry

  1. Oct 6, 2014 #1
    Hello. I need help with the following problem:
    Unavngivet.jpg Unavngivet1.jpg
    I dont know where to start. I know that the frame can be split up into one symmetric part and one symmetric+assymetric part but i forgot the theory and rules on translation and axis etc.
    I hope someone can help as I have to hand in the assignment soon and my grade depends on it.

    Best regards

    Sorry about your memory loss, but the policy at PF is that you must show some effort at a solution before you can receive help.
