Wall Panel with Openings

Configure vertical wall panels with windows, doors, and other openings. Complete control over opening sizes, positions, reinforcement, and edge conditions.

Functional Purpose¶

Wall Panel with Openings - Configures vertical precast panels including dimensions, multiple openings (windows, doors, louvers), edge treatments, reinforcement around openings, and connection details.

Key Functions:

Defines panel dimensions (width, height, thickness)
Creates multiple openings (up to 32 typical: windows, doors, MEP)
Positions each opening (horizontal and vertical coordinates)
Specifies opening types (window, door, louver, blank-out, etc.)
Configures edge returns (at openings: square, rounded, beveled)
Manages reinforcement (bars around openings, diagonal bars at corners)
Controls reveals (architectural features, rustication joints)

User Need¶

Wall panels with openings for:

Building facades (office, institutional, residential)
Exterior walls (windows, doors for light and access)
Load-bearing walls (structural + architectural)
Cladding panels (non-structural with large openings)
Parking garage perimeters (ventilation louvers, openings)
Privacy/security walls (small or no openings)

Typical Workflow¶

1. User in mp_dlg selects panel type: Wall OR clicks [Wall] button
2. wall_dlg opens
3. User sets panel dimensions:
   • Width: 12'-0"
   • Height: 10'-0" (one-story)
   • Thickness: 6"
4. User adds Window 1:
   • Type: Aluminum window
   • Size: 4'-0" W × 6'-0" H
   • Position: 2'-0" from left, 2'-0" from bottom
   • Frame: 1" reveal all around
5. User adds Door 1:
   • Type: Steel door + frame
   • Size: 3'-0" W × 7'-0" H
   • Position: 8'-0" from left, 0" from bottom (at grade)
   • Sill: None (at floor level)
6. User configures edges around openings:
   • Returns: 1/2" chamfer (architectural)
   • Corners: Diagonal bars (prevent cracking)
7. User adds reveal lines:
   • Horizontal reveal at mid-height (rustication)
   • Vertical reveals at panel thirds
8. User clicks OK
9. Wall panel elevation drawn with openings, reinforcement, dimensions

Control Semantics¶

Panel Dimensions¶

Overall Size:

wlw - Wall width (horizontal dimension):
- Typical: 8’-0”, 10’-0”, 12’-0”, 16’-0”, 20’-0”
- Based on: Building module, transportation limits
- Maximum: ~40’ (transportation, handling)
wlh - Wall height (vertical dimension):
- Single-story: 10’-12’
- Two-story: 20’-24’
- Maximum: ~60’ (handling, stability)
wlt - Wall thickness:
- Non-structural: 4”-6”
- Load-bearing: 6”-10”
- Insulated (sandwich): 8”-12” (2 wythes + insulation)

Opening Configuration (up to 32)¶

Opening Enable:

wlo1 through wlo32 - Opening toggles

Per Opening Controls:

Opening Type:

wlot1 - Opening type dropdown:
- Window opening (most common)
- Door opening (personnel, overhead, service)
- Louver opening (ventilation, HVAC)
- Blank-out (formed opening, later infilled)
- MEP penetration (small utility opening)
- Reveal/rustication (architectural, not through-opening)

Opening Dimensions:

wlow1 - Opening width (rough opening):
- Standard windows: 2’-0” to 6’-0”
- Standard doors: 3’-0” (single), 6’-0” (double)
- Large openings: 8’-0”+ (storefront, garage)
wloh1 - Opening height (rough opening):
- Standard windows: 3’-0” to 6’-0”
- Standard doors: 6’-8” to 8’-0”
- Full-height: 8’-10’ (storefront)

Opening Position:

wlox1 - X position (horizontal from left edge):
- Dimensioned from panel left edge
- To opening centerline OR left edge (specify)
wloy1 - Y position (vertical from bottom):
- Dimensioned from panel bottom
- To opening centerline OR bottom edge (specify)

Opening Frame:

wlof1 - Frame/reveal depth:
- Flush (no reveal) - 0”
- Standard reveal - 1” to 2”
- Deep reveal - 3” to 4” (shadow lines)
- Frame type: Steel, aluminum, wood

Edge Details at Openings¶

Return Type:

wlor1 - Edge return per opening:

Square Return:
- Perpendicular cut
- Simplest, most common
- Sharp corners (may chip)
Chamfered Return:
- 45° bevel (typically 1/2” to 3/4”)
- Architectural appearance
- Reduces spalling/chipping
Rounded Return:
- Radius corner (1/4” to 1” radius)
- Smooth appearance
- More expensive to form
Bullnose:
- Large radius (2” to 4”)
- Special architectural feature
- Requires custom forms

Reinforcement Around Openings¶

Corner Reinforcement:

wlor1 - Corner bar configuration:
- Diagonal bars (typical):
  - 2-#4 bars at each corner
  - Extend 24” minimum each direction
  - Prevents cracking at 45° angles
- L-bars (alternative):
  - Horizontal + vertical bars hooked together
  - Standard practice
- No additional bars:
  - For very small openings
  - Existing reinforcement sufficient

Lintel Bars (above openings):

wlol1 - Top reinforcement:
- Size: #4, #5, #6 bars
- Quantity: 2-4 bars typical
- Extension: 24” min beyond opening each side
- Purpose: Support load above opening

Sill Bars (below openings):

wlos1 - Bottom reinforcement:
- Size: #3, #4 bars
- Quantity: 2 bars typical
- Extension: 12”-24” beyond opening
- Purpose: Control cracking at sill

Reveals and Rustication¶

Architectural Reveals:

wlr1 through wlrN - Reveal lines:

Horizontal Reveals:
- Simulates multiple wythe courses
- Typical spacing: 2’-0”, 4’-0” o.c.
- Depth: 1/2” to 1” (shadow line)
Vertical Reveals:
- Panel division appearance
- Typical spacing: Panel thirds, quarters
- Creates modular appearance
Grid Pattern:
- Horizontal + vertical = checkerboard
- Common in institutional buildings
- Adds visual interest

Engineering Considerations¶

Opening Size Limits¶

Maximum Opening Size:

Rule of Thumb:
Opening area ? 50% of panel area (maintain structural integrity)

Example:
12' × 10' panel = 120 SF
Maximum opening: 60 SF
= 6' × 10' (full-height window, half width) OK
= 8' × 8' (large window) = 64 SF slightly over - check engineering

Small panels (< 8' wide):
Opening area ? 40% (less surrounding concrete for reinforcement)

Reinforcement Requirements¶

Diagonal Bars at Corners (Critical!):

Why Required:
Stress concentrations at opening corners
Diagonal tension cracks form at 45°
Without diagonal bars: WILL CRACK!

Standard Detail:
2-#4 bars at each corner (4 corners × 2 bars = 8 bars per opening)
Extend 24" minimum from corner
Lap with main reinforcement

For Large Openings (>6' wide or tall):
Increase to #5 bars or add more bars
Check with structural engineer

Lintel Design:

Load above opening:
Tributary width × height × load

Example:
12' panel, 6' window, 4' height above window
Load: 6' wide × 4' tall × 100 PSF = 2,400 lbs

Lintel capacity:
4-#5 bars, 6' span
Capacity: ~5,000 lbs (OK)

If insufficient: Add more bars or deepen lintel

Multiple Opening Spacing¶

Minimum Spacing Between Openings:

Horizontal: 
2'-0" minimum (16" absolute minimum if engineered)
Typical: 3'-0" to 4'-0"
Reason: Concrete between openings acts as "pier"

Vertical:
3'-0" minimum (24" absolute minimum)
Typical: 4'-0" to 6'-0"
Reason: Spandrel beam between openings

If closer: Treat as single large opening, infill afterward

User Example¶

   • Size: 3'-0" W × 7'-0" H
   • Position: 13'-0" from left, 0'-6" from bottom (raised sill)
   • Frame: Steel door frame
   • Return: Square
6. Reinforcement:
   • Main: #4 @ 12" o.c. vertical and horizontal
   • Diagonals at all opening corners: 2-#4 bars each
   • Lintels above all openings: 4-#5 bars, extend 24"
   • Sill bars: 2-#4 bars, extend 12"
7. Finish:
   • Exterior: Sandblast (exposed aggregate)
   • Interior: Smooth form finish
8. Reveals:
   • Horizontal reveal at 5'-6" (mid-height rustication)
9. Result: Facade panel with 2 windows, 1 door, architectural reveals

Integration¶

Called By: mp_dlg ? Panel Type ? Wall OR [Wall] button Drawing: wall.lsp generates elevation view with openings, reinforcement, dimensions

Variables:

wall-width, wall-height, wall-thickness
wall-openings[] - Array of opening definitions (type, size, position)
wall-reinforcement[] - Bar details around openings
wall-reveals[] - Architectural reveal lines

Calls:

opening.lsp - Opening generation
chamfer.lsp - Edge chamfers (if applicable)
Reinforcement generation modules

Best Practices¶

Opening Layout:

? Symmetric layout (balanced appearance)
? Align openings horizontally (consistent sill heights)
? Maintain minimum spacing (2’-3’ between openings)
? Center openings when possible (easier reinforcement)

Reinforcement:

? ALWAYS use diagonal bars at opening corners
? Extend lintel bars 24” minimum beyond opening
? Check capacity for large openings (>6’ span)
? Use continuous bars when possible (fewer splices)

Edge Details:

? Chamfer exterior edges (weather, chipping resistance)
? Square edges OK for interior
? Deeper reveals (1”-2”) for strong shadow lines
? Avoid very deep reveals (>2”) - hard to form

Common Mistakes:

? Openings too close together (insufficient pier width)
? Missing diagonal bars (WILL CRACK!)
? Undersized lintels (cracks above opening)
? Opening too close to panel edge (<12” - concrete breaks)
