Truss to support Fascia

  1. Feb 26, 2017 #1
    Hey guys, from the figure, I was planning to put a truss (shaded in the figure) to support the fascia, due to the fascia being too high (3m) and it may be unstable, thus adding the additional truss support. But my question is how do I calculate if that shaded truss is enough to support the fascia? Any idea guys? Thanks.

    P/S : Could've add a tie to the fascia, but I really do want to know if the truss can support the fascia..

    Thanks and best regards.

    Not enough information given. Is this a building? If yes I'm guessing a structural engineer must approve the design unless you live in a country where anything goes?

    Yep, it is a building, but a capstone design project in my university.

    That is not a very good design of support structure with or without the extra strut .

    See if you can come up with a much better one .

    Start the design process by identifying the magnitude and direction of the loading forces acting on the facia and marking them on a scale diagram of the facia and building wall .

    When you have done that work out the simplest system of structural members that will carry these loading forces back to the fixing points on the wall . Decide for yourself where the optimal positions for these fixing points are .

    This design process is essentially similar to use of free body diagrams for solving simple text book statics problems .
