Wall Rebar: all 86 settings
Open Detailing standard… for all 14 groups; use the main window Properties scope to override values. Deepest scope shows how specifically a field may be overridden: a Story group field cannot be overridden for just one Zone. Higher scopes still apply through inheritance. Units follow the UI; diameters are in mm. These explanations describe software controls, not a project reinforcement design.
Workflow and actual results · Increasing/decreasing reinforcement.
1. Materials & cover
① Field labels; ② values and allowed override scopes. Captured from the English UI in Revit; click to view the full screenshot.
| UI field | Deepest scope | How to use it and its output effect |
|---|---|---|
| Concrete | Story group | Select the model concrete grade; it changes calculated anchorage/lap lengths. Recheck the Lan/Ll table by diameter. |
| Longitudinal steel | Story group | Select the longitudinal steel grade for anchorage/lap calculations; this does not change diameter. |
| Tie / hook steel | Story group | Select tie steel grade; tie diameter is set separately under Boundary elements and S-ties. |
| Wall face cover | Story group | Cover to the outermost steel layer. Increasing it moves reinforcement inward and reduces room for the two layers. |
| Cover at slab top (top anchorage) | Core | Slab cover at the top anchorage; controls elevation and space available for the bend. |
| Cover at foundation bottom | Core | Bottom foundation cover; controls starter-foot elevation. |
| Horizontal bars placed | Core | Choose outside/inside vertical bars. This swaps layer order; check the section and boundary anchorage. |
2. Seismic
① Field labels; ② values and allowed override scopes. Captured from the English UI in Revit; click to view the full screenshot.
| UI field | Deepest scope | How to use it and its output effect |
|---|---|---|
| Seismic class | Core | Choose None/Low/Medium/High from the project design. Used for critical height hcr and detailing checks, not earthquake-load analysis. |
3. Vertical web bars
① Field labels; ② values and allowed override scopes. Captured from the English UI in Revit; click to view the full screenshot.
| UI field | Deepest scope | How to use it and its output effect |
|---|---|---|
| Diameter | Zone | Change vertical web-bar diameter. With unchanged spacing, mass, lap lengths and clearances can still change. |
| Max spacing a | Zone | Reduce 200→150 mm for denser bars; increase it for fewer bars. Equal distribution keeps actual spacing within this maximum; check the plan count. |
| Distribution | Branch | Equal spacing ≤a redistributes the run; fixed a with remainder at both ends keeps the interior pitch. Check bars next to boundary zones. |
4. Horizontal bars
① Field labels; ② values and allowed override scopes. Captured from the English UI in Revit; click to view the full screenshot.
| UI field | Deepest scope | How to use it and its output effect |
|---|---|---|
| Diameter | Story | Horizontal-bar diameter; recheck end, L/T anchorage and clearance to vertical bars. |
| Spacing a | Story | Reduce spacing to add horizontal rows; increase it to reduce rows. Check Elevation and generated-set Properties. |
| First bar above slab s0 | Branch | Offset from the slab surface to the first horizontal row. Increasing s0 raises that row and can change the remaining row count. |
| Continue through the slab zone | Branch | Enable horizontal reinforcement through the slab zone; disable to omit that zone. Inspect the wall/slab junction. |
| Free end / opening edge | Branch | U-bar joins the layers; 90° hook bends the end; None omits that end detail. Inspect free and opening edges in plan. |
| U-bar leg | Branch | For U-bars: use Ll or a fixed 300/400 mm leg. Changes the U anchorage/lap extent. |
| L corner | Core | Choose separate L-corner bars or continuous outer-face bending; changes horizontal paths and laps at corners. |
| T junction | Core | Choose a far-face 90° hook or U-bar around the flange; inspect anchorage into the T flange. |
5. Boundary elements (wall ends, opening edges)
① Field labels; ② values and allowed override scopes. Captured from the English UI in Revit; click to view the full screenshot.
| UI field | Deepest scope | How to use it and its output effect |
|---|---|---|
| Boundary element | Zone | Enable/disable the selected boundary zone. Disabling removes its boundary detailing; recheck end reinforcement and warnings. |
| Length lc | Zone | Choose formula max(0.15·lw;1.5·t), fixed length or bar-count-based length. Changes the boundary/web interface. |
| Fixed lc | Zone | Used for fixed lc. Enter boundary length in mm and check room for nX bars and clear spacing. |
| Bars per face nX | Zone | Bars per face, not the combined two-face count. Increase 3→4 for more boundary steel; check bar dots and restraint. |
| Diameter | Zone | Longitudinal boundary-bar diameter, independent of vertical web-bar diameter. |
| Closed hoop | Zone | Closed boundary-hoop diameter. Count is governed by a1/a2 and spreading lengths. |
| Hoop spacing inside hcr a1 | Zone | Hoop spacing inside critical height hcr. Reduce for denser hoops there; this is separate from a2. |
| Hoop spacing outside hcr a2 | Zone | Hoop spacing outside hcr. Reduce to increase hoop count in that region. |
| C-ties | Zone | Automatic when bars are more than 200 apart, select on canvas, or None. For manual layout inspect boundary-section restraints. |
| Hoops through the slab zone | Branch | Enable boundary hoops through slab zones. Separate from horizontal web bars through slabs. |
6. L / T / X nodes
① Field labels; ② values and allowed override scopes. Captured from the English UI in Revit; click to view the full screenshot.
| UI field | Deepest scope | How to use it and its output effect |
|---|---|---|
| L-node leg length | Core | L-node arm length equal to lc or 450/600 mm. Extending the node reduces adjacent web space. |
| T / X node extension each side | Core | Extension on each side of T/X nodes; check interaction with nearby boundaries and openings. |
| Diameter | Zone | Node-bar diameter, not the entire web mesh diameter. |
| Max spacing | Zone | Maximum node-bar spacing. Reduce for denser node steel and check clear spacing. |
7. S-ties (between the two layers)
① Field labels; ② values and allowed override scopes. Captured from the English UI in Revit; click to view the full screenshot.
| UI field | Deepest scope | How to use it and its output effect |
|---|---|---|
| Diameter | Zone | Diameter of S-ties linking the two layers; does not directly set their count. |
| Every … vertical bars | Zone | Place ties every N vertical bars. Reducing 2→1 increases horizontal tie density. |
| Every … horizontal bars | Zone | Place ties every N horizontal rows. Reducing 2→1 increases vertical tie density. |
| Pattern | Branch | Staggered offsets adjacent rows; Grid aligns them. Inspect the Ties/S-ties canvas layer. |
| Hooks | Core | Choose two 135° ends or alternating 135°/90°; inspect hook directions and Revit hook types. |
8. Vertical bar laps
① Field labels; ② values and allowed override scopes. Captured from the English UI in Revit; click to view the full screenshot.
| UI field | Deepest scope | How to use it and its output effect |
|---|---|---|
| Lap length Ll | Story group | Choose code calculation, factor×diameter or manual mm. The factor/manual field determines Ll only in its matching mode. |
| Treat wall bars as | Story group | Choose tension/compression assumption for calculated laps; changes Ll, not model loading. |
| Factor (when × Ø) | Story group | In factor×diameter mode, 40 with Ø16 gives 640 mm before rounding. Read the final Ll table. |
| Manual Ll | Story group | Used only in manual-mm mode. Check can still report LAP_SHORT for insufficient length. |
| Round up | Project | Round upward to 10/50/100 mm increments. Larger increments can increase final Ll. |
| Lap position | Story | Lap above slab+e0 or at mid-story. Changes lap elevation; inspect Elevation for insufficient vertical space. |
| e0 | Story | Offset above slab for slab-based laps; not the lap length Ll. |
| Stagger | Story group | 50% staggered with centers 1.3Ll apart, or 100% at one elevation. Changes lap grouping and required vertical space. |
| Web lap type | Branch | Contact lap or 1Ø crank (1:6) for web bars; inspect bar geometry at the splice. |
| Boundary / node lap type | Branch | Separate splice style for boundary/node bars; does not change web-bar splices. |
| Storeys per bar | Story group | One or two stories per bar; changes segmentation. Check stock-length limits and section-change stories. |
| Max stock bar length | Project | Stock-length limit for BAR_TOO_LONG checking; do not assume it automatically cuts every bar to that length. |
9. Storey transitions
① Field labels; ② values and allowed override scopes. Captured from the English UI in Revit; click to view the full screenshot.
| UI field | Deepest scope | How to use it and its output effect |
|---|---|---|
| Max offset to crank δmax | Branch | Maximum offset allowing a crank. Larger offsets can require terminated/anchored lower bars and embedded upper bars. |
| Crank slope 1 : n | Branch | Denominator n in 1:n. For a fixed offset, larger n needs more vertical length; check slab thickness and soffit warnings. |
| Anchor leg Lk | Branch | Automatic bend to meet total Lan, or fixed bend length, for the applicable terminated/transition bars. |
| Fixed Lk | Branch | Lk is used for fixed bend length. Check TOP_ANCHOR_SHORT and available space. |
10. Wall base (foundation)
① Field labels; ② values and allowed override scopes. Captured from the English UI in Revit; click to view the full screenshot.
| UI field | Deepest scope | How to use it and its output effect |
|---|---|---|
| Foundation starter bars | Branch | Separate creates foundation starters lapped to the lowest-story bars; Continuous extends the lowest bars into the foundation. |
| L foot | Branch | Foundation foot length. Increasing it extends the foot; check foundation edges and bottom cover. |
| Foot direction | Branch | Alternating, outward or inward feet; changes starter-foot direction. |
| Ties inside the foundation | Branch | Number of foundation hoops, separate from wall-zone spacing a1/a2. |
11. Wall top
① Field labels; ② values and allowed override scopes. Captured from the English UI in Revit; click to view the full screenshot.
| UI field | Deepest scope | How to use it and its output effect |
|---|---|---|
| Top anchorage | Branch | Bend into slab, U-cap or straight continuation. Choose the actual wall termination condition. |
| Hook direction | Branch | Auto-detect slab side, inward or outward; changes top-bend direction. |
12. Openings & lintels
① Field labels; ② values and allowed override scopes. Captured from the English UI in Revit; click to view the full screenshot.
| UI field | Deepest scope | How to use it and its output effect |
|---|---|---|
| Ignore openings smaller than | Project | Small-opening threshold; reduce to include smaller openings. Check recognized opening geometry on canvas. |
| Trim bars per opening edge | Zone | Enter count and diameter, e.g. 2Ø16 per opening edge. Compare added area with interrupted mesh steel. |
| Diagonal bars at opening corners | Zone | Enable diagonal corner bars; inspect direction and anchorage in a close-up. |
| Boundary element at opening edge | Zone | Auto for openings at least half clear height, or force On/Off at opening jambs; inspect both jambs. |
| Plain lintel | Zone | Enable an ordinary lintel with top/bottom bars and closed ties; not a substitute for diagonally reinforced coupling-beam design. |
| Lintel: top bars | Zone | Enter e.g. 2Ø16 for lintel top bars; check anchorage into both side walls. |
| Lintel: bottom bars | Zone | Enter e.g. 2Ø16 for lintel bottom bars, independently of top bars. |
| Lintel: stirrups | Zone | Enter diameter and spacing, e.g. Ø8 a150. Reducing a adds ties within the lintel span. |
13. Rebar output & data
① Field labels; ② values and allowed override scopes. Captured from the English UI in Revit; click to view the full screenshot.
| UI field | Deepest scope | How to use it and its output effect |
|---|---|---|
| Partition | Project | Rebar partition pattern, e.g. {Lõi}-{Nhánh}. Used for filtering/schedules; does not add bars. |
| Write storey to parameter | Project | Do not write, or write level into Schedule Mark/BS_LEVEL. Check the generated Rebar parameter. |
| Colour rebar in the view | Project | Color reinforcement in the view for identification; display only. |
| Show as solid in 3D | Project | Show solid reinforcement in 3D, subject to view display settings. This is not the preview 3D-tab button. |
14. Check thresholds
① Field labels; ② values and allowed override scopes. Captured from the English UI in Revit; click to view the full screenshot.
| UI field | Deepest scope | How to use it and its output effect |
|---|---|---|
| c_min face cover (COVER_MIN) | Project | Minimum-cover check threshold. Increasing it flags more cases; does not move bars inward. |
| Min clear spacing between bars (CLEAR_SPACING) | Project | Required minimum clear gap, not center-to-center spacing. Changing it does not move bars. |
| Min wall thickness (WALL_THIN) | Project | Wall-thickness warning threshold; does not change host thickness. |
| Max storey H / t (WALL_THIN) | Project | Maximum story-height/thickness ratio; exceeding it flags WALL_THIN. |
| Min junction angle (SKEW_JUNCTION) | Project | Minimum junction angle for skew-node warnings, in degrees; input is limited to 90. |
| Min S-tie density (TIE_DENSITY) | Project | Minimum S-ties per m². To add real ties, change the every-N vertical/horizontal-bar settings. |
| Boundary bar to nearest held bar ≤ (BE_UNRESTRAINED_BAR) | Project | Maximum distance to a restrained boundary bar. Fix restraint via C-ties/layout, not only this threshold. |
| Min pier lw / t beside a door (SHORT_PIER) | Project | Minimum opening-pier length/thickness ratio for SHORT_PIER warnings. |
| Hooked anchorage factor α (H_TEE_ANCHOR) | Project | Factor checking total hooked T-anchorage against Lan; changes the check criterion. |
| Min crank slope 1 : n (CRANK_SLOPE) | Project | Minimum acceptable 1:n crank slope. Actual geometry is controlled in Story transitions. |
| Max crank offset (CRANK_SLOPE) | Project | Maximum crank offset accepted by checks; separate from the δmax planning control. |
| Crank allowed below slab soffit (CRANK_BELOW_SOFFIT) | Project | Allowed crank extension below slab soffit in mm. Zero allows none; inspect Elevation to resolve geometry. |
| Thicker wall overhang over the wall below ≤ (STACK_GAP) | Project | Allowed upper-wall overhang beyond the lower wall; flags STACK_GAP without modifying the model. |
| Opening trim ≥ … of the cut steel (OPENING_TRIM) | Project | Opening trim area as a percentage of interrupted steel. Increase actual reinforcement with the opening-trim control. |
Entering and applying values
Numeric fields accept nonnegative values with a dot or comma decimal separator; relevant spacing/count/length fields require positive values. Enter whole numbers for counts. Reinforcement text must contain Ø, e.g. 2Ø16 or Ø8 a150; a bare diameter is not a lintel reinforcement specification. Resolve input errors before Save / Apply to project. Run Check, review the preview, then Create reinforcement and inspect actual Rebar in 3D. Changing a warning threshold does not fix inadequate detailing.
