Composite frame help

  1. Apr 30, 2009 #1
    1. The problem statement, all variables and given/known data

    I need to find the Exact Solution for this problem(Displacements)
    I already did it using MATLAB but I need to compare it to the exact solution
    I am not sure what equations to use for this problem and where to start?

    2. Relevant equations

    -Plane strain
    -E and v are given
    -no thickness
    -length of members are in ( )

    3. The attempt at a solution

    Break it into four elements and find the force on each side
    i.e E2, E3 and E4 have forces pulling but I am not sure what to do about the sharing force for (2) inbetween E3 and E4 and E2 and E4

    If anyone can help it would be greatly appreciative
