    beam equation needed

    Kelly et al:

    Do we have an equation / calculation for the following:
    Continuous Beam, with multiple Unequal Spans, multiple unequal, non-uniform loads.

    I know we have one that is close:
    Continuous Beam, with Two unequal Spans, Unequal, Uniform Loads

    For the sake of example, let's assume:
    a continuous beam, supported at 4 points (not uniformly distributed),
    resulting in 3 spans, with each span supporting 3 point loads, not uniformly distributed.

    What I am actually looking for is the load on each support.

    Dale, see the following:

    Be aware that the loading per side is total as opposed to line loading. I don't have an automated script but hey you got a calculator.

    Let me know..

    Here is the beam Bending calculations menu..

    Yea, I saw that one earlier.
    But it assumes a uniform load, not point loads x distance from a support.

    Here is a picture of what I'm talking about.
    I'm not sure how to modify this equation:
    http://www.engineersedge.com/beam_be..._bending21.htm
    to incorporate non-uniform supports and non-uniform loading.

    Supports can be anywhere along the truss, loads can be located anywhere along the truss.

    The goal is to find the tension on each support line.

    Any ideas?
