Constrained reinforcement on different planes

BrentBurgess1980 — Thu, 05 Nov 2020 11:24:54 GMT

Hi all,

I have a bridge that is sloped transversely. The main bars are all constrained, however, I need some bars bending down into the abutment, but be vertical.

If I create the bars from the main bars, I can constrain them to the lapping bars, however the legs are not vertical (not suitable)

If I create the bars from a longitudinal section and set the rebar to varying rebar set, the ends are vertical, but I can't constrain them to the lapping bars.

Is there a way that I can do both?

Thanks,

Brent

Are those the same bar?

In Revit a bar that overlaps itself shifts one of the segment so that it doesn't clash. An example is a stirrup.

The shift is only for representing the 3D solid. The constraint is to the end vertical plane.

Thanks @ovidiu_paunescu for the reply. They aren't the same bars. One is straight, and one is cogged. I hope the image clarifies.

Maybe you can share a simple rvt sample file.

If those bars are rotated it means the bar plane is not parallel to the other bar, so you can't contrain them together.

One way to get those bars like that is probably by using a varying rebar set.

Another way to have them slightly rotated is to use a hook and rotate as needed (starting with Revit 2021)
