Summary: Enable a means to position slab and wall reinforcement by layer, automatically staying in position and locked as bar sizes change. This should enable custom bar shapes to remain without issue.
Description: I wish that rebar can be placed and locked according to layer placement.
a slab in multi-storey infrastructure building
(ie power substations) where reinforcement transitions from heavily to lightly loaded areas, bridge slabs, precast girders.
Some situations are:
1) N20 bars transition into N32 bars parallel and in the same layer (plane). Would like to move together.
2) Double layer of top and bottom reinforcement in beams with spacers bars.
3) Ligs are not always on the outside (closest to the concrete edge), sometimes the reinforcement is on the outside and ligs are in the inside. Ligs used as secondary bars for shear and crack control.
4) Custom bar shapes in precast girders that use lig radius.
How Used: I'd like to be able to define the plane for each layer of reinforcement based from the outside cover into the centre and lock the reinforcement to that layer such as;
Slab example
Top Top (layer 1)
Top Bottom (layer 2)
Bottom Top (layer 2)
Bottom Bottom (layer 1)
Beam example with double layer of reinforcement.
Looking at a beam cross section top down
Lig - top part (layer 1)
Top Top (layer 2)
Spacer (layer 3)
Top Bottom (layer 4)
Bottom Top (layer 4)
Spacer (layer 3)
Bottom Bottom (layer 2)
Lig bottom part (layer 1)
Looking at a beam cross section side to side
Lig - left side(layer 1)
Left side bars (layer 2)
Right side bars (layer 2)
Lig - right side(layer 1)
This would be extremely useful for precast girders if you could define reinforcement layers so that custom bar shapes would be lock to layers rather than with every modification the bars being either deleted or thrown outside the concrete shape.
Feature Affinity: Reinforcement (individual, area, path, shapes)
