Note

Foundation Connection Feature

Configure anchor bolts and base plates for panel-to-foundation connections. Critical for panel stability and structural integrity during erection.

Functional Purpose¶

What This Dialog Does¶

Base Plate & Anchor Bolt Configuration

The bp_dlg provides foundation connection design that:

Positions anchor bolts at panel base
Configures base plate embedments
Auto-placement with grid patterns (1-8 columns × 1-4 rows)
Manual precise positioning for custom requirements
Face direction control (left/right face)

User Need¶

Panel-to-Foundation Anchoring

Users need to:

Secure panels to foundation/slab
Position bolts for structural loads
Comply with engineering requirements
Create erection anchor patterns
Specify bolt sizes and types

Typical Workflow¶

Adding Anchor Bolts to Panel:

User in mp_dlg clicks [Base Plate]
bp_dlg opens (similar to pp_dlg layout)
User enables auto-placement (bpa checkbox)
User selects grid: 4 columns × 1 row
System calculates equal spacing
Bolts positioned at base of panel
User reviews engineering feasibility
User clicks OK
Returns to mp_dlg
On generation, anchor symbols drawn

Dialog Structure¶

Visual Layout¶

Nearly identical to pp_dlg (pick points) but for base plates:

Global Variables¶

Variable Patterns:

Auto-Placement:

bpr - Row count (“1” to “4”)

Anchor Positions (32 max):

bpd1…bpd32 - Distance from edge

User Interaction Examples¶

Example 1: Standard 4-Bolt Foundation¶

Scenario: 12’ panel needs 4 anchor bolts

1. User: Opens bp_dlg from mp_dlg
2. User: Checks [x] Auto place
3. User: Selects Columns: 4, Rows: 1
4. System: Calculates positions:
   • bpd1 = 2'-6" (quarter point)
   • bpd2 = 5'-0"
   • bpd3 = 7'-6"
   • bpd4 = 10'-0"
   • All at bpe = 0'-6" (6" above foundation)
5. User: Clicks OK
6. Result: 4 anchor bolts equally spaced at base

Example 2: Heavy Panel - 6 Bolts¶

Scenario: Large/heavy panel needs more anchorage

User: Opens bp_dlg
User: Auto-placement enabled
User: Selects Columns: 6, Rows: 1
System: 6 bolts @ 2'-0" spacing
Engineer: Reviews and approves pattern
Result: Enhanced foundation connection

Example 3: Custom Corner Bolts¶

Scenario: Special anchoring at corners only

1. User: Opens bp_dlg
2. User: Disables auto-placement
3. User: Manually enters:
   • bpd1 = 1'-0" (near left edge)
   • bpe1 = 0'-6"
   • bpq1 = L (left face)
   • bpd2 = 11'-0" (near right edge)
   • bpe2 = 0'-6"
   • bpq2 = R (right face)
4. Result: 2 corner anchor bolts only

Engineering Considerations¶

Critical Warning¶

“Must be verified by Engineer”

Why Critical:

Anchor bolts prevent panel tipping
Insufficient anchorage = safety hazard
Must resist wind loads, seismic forces
Bolt capacity depends on:
- Panel weight
- Panel height
- Wind exposure
- Seismic zone
- Foundation concrete strength

Best Practices¶

Typical Patterns:

Small Panels (< 10’):

2-4 anchor bolts
Spacing: 4’-0” to 6’-0”

Medium Panels (10’-16’):

4-6 anchor bolts
Spacing: 2’-6” to 4’-0”

Large/Tall Panels (> 16’):

6-8 anchor bolts
Closer spacing for stability

Edge Distance:

Minimum: 6” from panel edge
Typical: 12” to 18” from edge

Load Calculations¶

Simplified Check:

Uplift Force = Wind Pressure × Panel Area
Required Anchorage = Uplift / (Bolts × Bolt Capacity)

Safety Factor: 2.0 minimum

Professional Engineering Required

Special Features¶

Auto-Calculation Algorithm¶

Spacing Formula:

; Equal spacing across panel width
(setq spacing (/ panel-width (+ columns 1)))

; Position N
(setq position (* N spacing))

Example (12’ panel, 4 bolts):

Spacing = 12' / (4 + 1) = 2.4' = 2'-5"
Positions: 2'-5", 4'-10", 7'-3", 9'-8"

Elevation Defaults¶

Base Plate Elevation:

Typically: 0’-6” (6” above foundation top)
Allows for foundation imperfections
Provides clearance for bolt installation

Can be adjusted:

Higher for tall foundations
Lower if flush mount required
Per structural engineer requirements

Face Direction¶

Left vs Right Face:

Determines which side bolt protrudes
Important for:
- Panel orientation during erection
- Crane access
- Adjacent panel clearance

Foundation Connection Feature¶

Why IMPORTANT:

Structural Safety: Primary panel anchorage to foundation
Erection Critical: Panels must be secured during/after installation
Code Compliance: Building codes require proper anchoring
Wind/Seismic: Resists lateral and uplift forces

Impact of Errors:

Panel instability
Tipping hazard
Code violations
Costly field corrections

Comparison with Pick Points (pp_dlg)¶

Similarities¶

Both dialogs:

Auto-placement with grid
Manual position override
Engineering verification required
Face direction selection
8×4 grid capacity (32 positions)

Differences¶

Aspect	bp_dlg (Base Plate)	pp_dlg (Pick Points)
Purpose	Foundation anchorage	Lifting/handling
Location	Base of panel only	Any height
Typical Elevation	0’-6” (at base)	Mid-height to top
Load Type	Uplift, lateral	Vertical lifting
Permanence	Permanent anchorage	Temporary hardware
Symbol	Anchor bolt (M-shape)	Pick point (circle)

Technical Notes¶

Naming Inconsistency¶

Dialog Label: “Brace Point Details” Actual Function: Base Plate / Anchor Bolt configuration

Historical Note:

May have been called “Brace Points” in earlier versions
Terminology evolved to “Base Plate” or “Anchor Bolts”
DCL title not updated
Functionality clear from context

Control Naming¶

Pattern:

bp prefix = Base Plate
a = Auto toggle
c = Column count
r = Row count
d = Distance
e = Elevation
q = Face (which face)

Grid Capacity¶

Maximum: 8 columns × 4 rows = 32 anchor bolts

Practical Limits:

Most panels: 2-6 bolts
Large panels: 6-12 bolts
Rarely need full 32 capacity
