    hello crazy engineer!! cn u guys guide me to do this..i just finish my last sem exam and get this job...im got no experience at all in this field TT...this is just to crazy for me...
    im supposed to check if this truss is safe...ive attached its picture..

    width of arc = 129'
    rise=7'(for now)
    supporting column height = 9m
    top chord = 5" black pipe , btm chord = 5" black pipe (grade A)
    member inside = 2" black pipe (grade B)
    support = pin-pin (my assumption)

    loading > roof material+purlin ( 2kn/m2)
    > wind loading = nil (no idea)

    i am really gratefull if u guys cn help me on this...>.<

    Is there any soft ware available with you or you are expected to do it manually?

    Hmm...... then its a bit tidious
    Preliminary you can start of for gravity loads.
    calculate UDL and moments assuming one side pinned other side roller
    calculate forces by method of joints
    wind loads you need to refer corresponding code

    For the given joint I think you can assume it to be straight. Discuss it with the one whom you need to submit. Each one has their own way of thinking.
    By the way which company and where are you working out this for?
    I believe instead of discussing it here, better do it with your senior face to face.
    Just getting an idea here is more than enough.....what say?

    is it a trussed arch or a space trussed arch. the arch will create a horizontal force at each end of the support. therefore u need to provide a horizontal tie at the supports. u u don't want to provide horizontal ties, then the posts have to be designed at cantilever beam column with the horizontal forces transfer to the foundation by means of a transfer footing or piles.

    for design purpose, sap2000 will be the job.
    for a trussed arch, watch the following clip,
    for a space trussed arch, watch the following clip,
