Risa Plate Design for Built-up Truss Plates

[smokiibear]

Curious if anyone has direction for working with plates in Risa 3D. Particularly, I'd like to look at built-up truss plates.

Any pointers would be appreciated.

Thanks.

smokiibear, while I am not 100% sure what you are trying to do you may want to start with the Help section specifically concerning plates in RISA-3D:

https://risa.com/risahelp/risa2d/Content/3D_2D_Only_Topics/Plates.htm.

If what you are trying to do is model the plates that connect members in a truss (steel or wood) together than I would suggest utilizing rigid links (see the image below - rigid links shown in green).

This would allow you to more accurately model the truss (such that the members frame into each others edges rather than at the centerline).

If on the other hand, what you desire is to investigate the plate itself, then you can model the plate and then would need to connect various nodes of the plates to the 1D members using rigid links. This would effectively create an assembly that ties everything together.
