Question on moment distrobution with sway

  1. Nov 7, 2008 #1
    hello there i have this question that seems quite compilcated, i was hoping some one could help me into solving it.

    basically i have a frame that can be seen in the diagram, i have to work out the vertical and horizontal components at point D. i was curious as to how i can do it.

    i know it works on the principles of useing total moments = moments before sway + a(moments after sway) but i am a little concerned with the applied forces being on the joints themselves, along with the incline of both AB and CD - which makes it harder to find the orgin of rotation.

    any help would be appricated thanks

    if you are confused to disintegrate your frame member where a force on it you can cut your pins(joints) locations like in this [​IMG]

    and consider as these cuts are so close to joints and then cont. as you solve cut in any point of member where there are normal, shear and internal moments are exist
