Pulling Rebar from Analytical iTwin
RAM Concept pulls only Analytical iTwin rebar that reinforces slabs or beams that are also being imported. RAM Concept does not pull non-horizontal Analytical iTwin rebar. It also does not pull any incompletely defined Analytical iTwin rebar type.
| Rebar Type | Required Properties |
|---|---|
| Analytical iTwin Concentrated Surface rebar |
|
| Analytical iTwin Area Surface rebar |
|
| Analytical iTwin Layer Parallel rebar |
|
| Analytical iTwin Perpendicular rebar |
|
Analytical iTwin Anchor, Hook90, Hook180 and None (straight) rebar end types are supported. An Unset or Other hook type is imported as straight. Hook135 is imported as a 90 degree hook. LapSplice, OffsetLapSplice, MechanicalSplice and WeldedSplice are imported as anchors.
RAM Concept pulls Analytical iTwin Concentrated Surface Rebar and Analytical iTwin Area Surface Rebar into RAM Concept as User Concentrated and User Distributed rebar. Analytical iTwin Layer Parallel Rebar that are in an imported beam are transferred as User Concentrated rebar.
Puling Perpindicular Rebar from Analytical iTwin
When pulling Analytical iTwin Perpendicular Rebar, RAM Concept first clusters together groups of Analytical iTwin Perpendicular to define stirrups of 3 or more. Any Straight Perpendicular rebar that starts and ends on the first and last stirrup bar of a Rectangular Tie or Open U Tie rebar is considered an interior leg of the stirrup. The Straight Perpendicular rebars do not have to be spaced uniformly or parallel to the Rectangular Tie or Open U Tie rebar.
The groups of Analytical iTwin Perpendicular rebar are considered User Transverse Rebar candidates, with the Rectangular Tie or Open U layout path. The intersection of each candidate's path with each beam or slab generates a separate RAM Concept User Transverse Rebar. Priority is given to beam intersections where the candidate path intersects both.
It may be the case that a single RAM Concept User Transverse Rebar—drawn across nonuniform slab geometry—will be transferred as several groups of Analytical iTwin Perpendicular rebar. When the RAM Concept model is updated from Analytical iTwin, the original User Transverse Rebar object's geometry will be changed, and new User Transverse Rebar objects will be added for the additional Analytical iTwin Perpendicular rebar.
