Importing ISM Rebar into Concept
RAM Concept imports only rebar that reinforces slabs or beams that are also being imported. RAM Concept does not import non-horizontal ISM rebar. It also does not import any incompletely defined ISM rebar type.
| Rebar Type | Required Properties |
|---|---|
| ISM Concentrated Surface rebar |
|
| ISM Area Surface rebar |
|
| ISM Layer Parallel rebar |
|
| ISM Perpendicular rebar |
|
ISM 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 imports ISM Concentrated Surface Rebar and ISM Area Surface Rebar into RAM Concept as User Concentrated and User Distributed rebar. ISM Layer Parallel Rebar that are in an imported beam are imported as User Concentrated rebar.
Importing ISM Perpindicular Rebar
When importing ISM Perpendicular Rebar, RAM Concept first clusters together groups of ISM 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 ISM 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 exported as several groups of ISM Perpendicular rebar. When the RAM Concept model is updated from ISM, the original User Transverse Rebar object's geometry will be changed, and new User Transverse Rebar objects will be added for the additional ISM Perpendicular rebar.
