Varying Rebar Set - How to edit rebar constraints

[asaundersZX5X6]

I am attempting to create a varying rebar set and am having difficulties. One side of the slab is angled and the other sides are straight. When I try to edit rebar constraints the constraints are set to the two parallel sides without the slope. I think this might be the issue and that the constraints need to be set to the opposite sides (with one side angled and one side straight). If this is the issue I cannot figure out how to change the constraints to the appropriate sides. Any help would be appreciated. Thanks.

 Hi, asaundersZX5X6,

I'm Judy, a Revit specialist, and I'll be happy to try to help you out with your question. I see you're trying to edit rebar constraints and are having trouble resetting them to the appropriate side. I found this information in the Revit help: Edit Rebar constraint behavior in a host. Does this help you? If not, perhaps you can send a screenshot or two so we can see what you've got and how you want to make it different. 

Let me know if you have any other questions!

Cheers,

Are there any reasons you are not using Structural Area Reinforcement tool?  Sorry, I am not a structural engineer so it can be a total noob question.

Hi Judy,

I think I may have determined my issue. I was trying to add a varying rebar set to a slab with a partial portion of one side sloped. My assumption was that you could have the bars follow the slope and then have the bars in the same set follow the straight line. I was not able to get this to work however, I was able to accomplish through using 2 rebar sets, one at the slope and one at the straight portion. Does this seem like the appropriate way to accomplish this?

Thanks.

The structural area tool is looking for a floor or a wall. I am adding reinforcement to a precast slab beam. When I try this tool with the beam I am not able to select the beam so I am not sure this tool is applicable for reinforcing beams. Is this correct?

Thanks.

Hi, asaundersZX5X6, 

I'm glad you found a workable way to model the rebar by creating two separate sets, one for the sloped part and one for the flat part. Without seeing an image of what you are doing, or the model itself, it's hard to comment in detail (I may be envisioning something different from what you are doing!) but if it works and the rebar design is what you expect it to be, I don't see a down side. Maybe other structural designers out there might have some additional comments; I'm not a structural designer so if someone sees a problem with this approach please let us know! 

I don't know what version of Revit you are using, but I looked for a few other resources for you that might be helpful, and found this video on Rebar Constraints Improvements for Revit 2016.

Also, see Area Reinforcement does not slope with slab

In response to your other question about adding reinforcement to a precast beam, in which you are unable to select the beam to apply reinforcing to it, please see About Reinforcement, which may help you determine why you're unable to select the beam (it may not be a valid host as described in the article). 

I hope this is helpful. If you need more help, it would be great if you could post a sample project with just the elements in question so we can all see exactly what you're doing and understand the issue better. Let us know!

Thanks,

Judy_S
