Direct Stiffness Method 2D Frame

  1. Nov 2, 2009 #1
    Hi all

    I am looking for a way of estimating stress and displacement of the following frame. I used ANSYS to analyze it, but still need some comparison.

    I think that I will use Direct stiffness method as a way of finding displacement etc. but as it would be the first time I use this method, I really need a good advice or a way of approach into this. (another method would do ok)

    Given
    A: 144 mm^2 (20x20x2)
    Izz: 7872 mm^4
    E: 210 GPa (steel)

    l1: 740 mm
    l2: 380 mm
    l3: 180 mm

    w1: 300 N/m
    w2: 400 N/m
