Rebar for custom concrete shape

[autoMick]

Hi,

I'm looking at using RS2014 to provide a basic rebar plan for a small concrete weir along with material quantities. I'm not sure if I'm doing this most effectively and would appreciate any guidance. The attached show a simple test file (the actual structure is a bit more complex). To make the concrete, I just model an extruded mass in place as a structural foundation. Then to add rebar, I sketch the hoops in place, and add straight dowels perpendicular. Is this the best way? Could someone point me to a good tutorial for this sort of thing?

Some specific questions:

- how can I modify the hooks on the rebar to be different from 90 or 180 degrees?

- how can I draw overlapping rebar on the hoops?

- how can I get the array of perpendicular rebar to snap to the rebar cover boundary of the concrete, and then the rebar hoop to snap to the perpendicular bars?

- I can get a schedule of the quantities (volume of steel), but don't know how to apply density and cost factors so that these appear in the schedule.

- Instead of adding the arrays of horizontal rebar, is there someway to attach area mesh to this sort of shape?

Any help or suggestions much appreciated

Thanks

- Mick

Thank you for your posting.

Q1. To modify hooks of the structural rebars,

1. From Project Browser, you will be able to see Rebar Hook family types loaded into your project under Famlies > Structural Rebar > Rebar Hook.
2. If you select the Type and double click or right-click and select Type Properties, Type properties dialog results.
3. You will be able to edit Style/Hook Angle/Extension Multiplier.
4. If you would like to create a new type, click "Duplicate...", and rename it.

Q2. Draw overlapping rebar on the hoops

Could you give us more explanation? Screenshot, maybe?

Q3. Array of perpendicular rebar to snap to the rebar cover boundary of the concrete and hoop

1. Create a section and from a section view,
2. Go to Structure > Rebar > and choose "Perpendicular to Cover" as Placement Orientation.
3. Select Rebar shape as "Rebar Shape: 00".
4. To create Rebar Set or Rebar array, select preferred option from "Layout", in my case, selected "Maximum Spacing".
5. Click "Sketch Rebar".
6. Then, Rebar set will appear on the sketch view. Currently rebar cover is set to 28mm, you will be able to create beyond 28mm offsetted region from the surface.  
   
7. Place the bar set by clicking in the position in the view.
8. After finishing the sketch, select this bar set and go to Modify|Structural Rebar > Host > Edit Constraints.
   
9. Then, you will be able to adjust the offset value from the Face of the concrete structure, as well as Start/End position of the bar set.

Q4. Schedule of the quantities (Volume of steel, according to density and cost)

If you have set the material for the Rebar Type, you can set the material properties in Material Browser.

1. From Type Properties, under Material, click "..." to result "Material Browser".
2. Select the material for the steel, and from the right plane, go to "Physical" tab. Go to Mechanical > Density, and set the value.
3. Apply and click OK.

Regarding cost, you can schedule cost by Types. To use this cost parameter, you might have to create a shared parameter to calculate the total cost.

Q5. Area mesh to custom shape structural 

Area reinforcement and Fabric rebar can be placed on Wall or Floor elements.

Thank you.

Cheers Yuri, I think that covers it - my question 2 was related to the hooks - which you answered.

Thanks for the detailed reply
