Truss Joint
Truss Joint
(OP)
Hi All,
I am designing a truss structure which will see an equipment of 60 Tonnes sitting on it. I have done the analysis and everything is fine. While modeling the truss structure, I am not being able to make a proper joint for the diagonal brace. Please see attached picture. The joint is made where the the axis of the beams meet, but is there any other way to make a "clean joint"? Thanks in advance.
Regards,
HD

looking at the diagonals on the long face (hiding behind the vertical in your pic), personally i'd have the two diagonals intersect at the top flange (rather than at the mid-depth of the horizontal) so that you're connected the two diagonal webs directly, and don't have two welds beside each other.

I have seen this done by coping the flange of the diagonal and bolting it to a plate that is welded to the top if the bottom cross beam.
I'm having trouble finding a good example but this link from Structure Mag shows how the plate is used to stay out of the corner.

Why don’t you enlist the help of a Structural Engineer familiar with this kind of steel framing. Now that we have FEA and CAD programs which almost anyone can pretend to use, everyone can be a Structural Engineer, for a day. A good share of the cost and final performance of these types of structures has to do with good clean detailing and fabrication which still meets the needs of the situation. Why is your truss unsymmetrical? Why don’t you show a plan and side view of your system, with loads, dimensions, other important design info. and to reasonably accurate proportions. This will allow us to see what you are actually dealing with. Two engineers can most often sit at a table and discuss an engineering problem and do some rough sketches and come to a meeting of the minds. But, that discussion starts from the basics, not from a CAD drawing of an overly complexified structural detail, or truss, because nobody know any better, but the computer dictates. You will get better help if you start from the beginning.

I thought it was more for machine designers working on pieces parts.
