ASCE 7-22 Loads and Design Skill
Purpose
This skill provides comprehensive access to ASCE 7-22 (Minimum Design Loads and Associated Criteria for Buildings and Other Structures), the authoritative US standard for determining structural loads.
Critical Distinction: ASCE 7 is a LOADS standard, not a material design standard. It tells you WHAT loads to apply, not HOW to design members.
When to Use This Skill
Trigger this skill when users ask about:
- Load combinations (LRFD, ASD)
- Wind loads, wind speed, exposure categories
- Seismic loads, base shear, response spectra
- Snow loads, ground snow, snow drift
- Load calculations per ASCE 7
- Risk Categories, Seismic Design Categories
- Environmental loads (tsunami, flood, ice, rain)
Do NOT use for:
- Steel member design → Use AISC 360
- Concrete member design → Use ACI 318
- Material properties, connection design

Workflow Types
1. Formula Query Workflow
Trigger: User asks for a specific formula or equation
Process:
- Identify the load type (wind, seismic, snow, etc.)
- Use
smart_search.pyto find relevant chapter - Use
formula_finder.pyto extract formula with context - Present formula with:
- Equation number (e.g., "Eq. 12.8-1")
- Variable definitions
- Context (when to use, limitations)
- Units
Example:
User: "Show me the seismic base shear formula"
Response:
The seismic base shear is calculated using Equation 12.8-1:
V = CsW
Where:
- V = Seismic base shear
- Cs = Seismic response coefficient (Eq. 12.8-2 through 12.8-6)
- W = Effective seismic weight
From Chapter 12, Section 12.8: Equivalent Lateral Force Analysis
The seismic response coefficient Cs is determined by:
Cs = SDS / (R/Ie) [Eq. 12.8-2]
Subject to:
- Cs need not exceed: Cs = SD1 / [T(R/Ie)] [Eq. 12.8-3]
- Cs shall not be less than: Cs = 0.044SDSIe ≥ 0.01 [Eq. 12.8-5]
Reference: ASCE 7-22 Chapter 12.8
2. Load Combination Query Workflow
Trigger: User asks about load combinations, LRFD, ASD
Process:
- Determine design method (LRFD or ASD)
- Identify all applicable loads
- Use
load_combinator.pyto generate combinations - Explain when each combination controls
- Note any special requirements (flood, seismic, ice)
Example:
User: "What LRFD load combinations do I need for Dead, Live, Wind, and Snow?"
Response:
For LRFD with D, L, W, and S loads, use these combinations per ASCE 7-22 Chapter 2:
1. 1.4D (Eq. 2.3-1)
2. 1.2D + 1.6L + 0.5(Lr or S or R) (Eq. 2.3-2)
3. 1.2D + 1.6(Lr or S or R) + (L or 0.5W) (Eq. 2.3-3)
4. 1.2D + 1.0W + L + 0.5(Lr or S or R) (Eq. 2.3-4)
Note:
- Combination 1 typically controls for compression members
- Combination 2 usually controls for live-load-dominated structures
- Combination 4 typically controls when wind is significant
- For each combination, check both +W and -W directions

3. Calculation Query Workflow
Trigger: User wants to calculate a specific load value
Process:
- Identify calculation type (wind pressure, base shear, snow load, etc.)
- Gather required inputs from user
- Reference appropriate chapter sections
- Show step-by-step calculation with equation numbers
- Provide final result with units
Example:
User: "Calculate wind pressure for 120 mph, Exposure C, at 30 ft height"
Response:
Wind pressure calculation per ASCE 7-22 Chapter 26:
Step 1: Velocity Pressure (Eq. 26.10-1)
qz = 0.00256 Kz Kzt Kd Ke V²
Given:
- V = 120 mph (basic wind speed)
- Exposure C
- z = 30 ft
Assuming:
- Kz = 0.85 (Exposure C at 30 ft, from Table 26.10-1)
- Kzt = 1.0 (no topographic effects)
- Kd = 0.85 (assuming Risk Category II, Table 26.6-1)
- Ke = 1.0 (sea level)
qz = 0.00256 × 0.85 × 1.0 × 0.85 × (120)²
qz = 28.3 psf
Reference: ASCE 7-22 Section 26.10
4. Terminology Query Workflow
Trigger: User asks "what is..." or definition questions
Process:
- Search
glossary.mdfor term - If not in glossary, search chapter text
- Provide definition with context
- Link to relevant chapter section
- Give practical example if helpful
Example:
User: "What is Seismic Design Category?"
Response:
Seismic Design Category (SDC) is a classification from A through F that determines the level of seismic design requirements for a structure.
Per ASCE 7-22 Chapter 11.6:
- SDC A: Minimal seismic risk
- SDC B-C: Moderate seismic risk
- SDC D-F: High seismic risk (most stringent requirements)
SDC is determined by:
1. Risk Category (Table 1.5-1)
2. Site Class (Chapter 20)
3. Spectral Response Parameters (SDS, SD1)
4. Using Tables 11.6-1 and 11.6-2
Higher SDC requires:
- More rigorous structural system requirements
- Greater detailing requirements
- Additional analysis procedures
- Special inspection
Reference: ASCE 7-22 Section 11.6
5. Symbol Query Workflow
Trigger: User asks about a variable or symbol
Process:
- Check
symbols.mdreference file - Search relevant chapter for symbol definition
- Provide:
- Symbol meaning
- Units
- Typical range of values
- Where it's used
Example:
User: "What does SDS mean in seismic design?"
Response:
SDS = Design spectral response acceleration parameter at short periods
Per ASCE 7-22 Section 11.4.5:
- Units: Dimensionless (fraction of g)
- Calculated as: SDS = (2/3) Sms
- Where Sms = MCER spectral response acceleration (short period)
SDS is used to:
1. Determine Seismic Design Category (Table 11.6-1)
2. Calculate seismic response coefficient Cs (Eq. 12.8-2)
3. Determine structural system limitations
Typical values:
- Low seismicity: SDS < 0.167g
- Moderate: 0.167g ≤ SDS < 0.50g
- High: SDS ≥ 0.50g
Reference: ASCE 7-22 Sections 11.4.5, 11.6
6. Risk/Design Category Query Workflow
Trigger: Questions about building classification, risk category, SDC
Process:
-
For Risk Category:
- Reference Table 1.5-1
- Ask about building occupancy/function
- Determine Category I, II, III, or IV
-
For Seismic Design Category:
- Need: Risk Category, SDS, SD1, Site Class
- Use Tables 11.6-1 and 11.6-2
- Determine SDC A through F
Example:
User: "How do I determine the Risk Category for an office building?"
Response:
Risk Category determination per ASCE 7-22 Table 1.5-1:
Standard Office Building:
- Occupancy: Business (office)
- Risk Category: II (default for most buildings)
Risk Categories explained:
- **Category I**: Low hazard (agricultural, minor storage)
- **Category II**: Standard occupancy (offices, residential, retail) ← Most common
- **Category III**: Substantial hazard (schools, jails, large assembly)
- **Category IV**: Essential facilities (hospitals, fire stations, emergency shelters)
Impact of Risk Category:
- Importance factors (Ie for seismic, Is for snow)
- Load duration and return periods
- Seismic Design Category determination
For your office building, use Risk Category II unless it:
- Houses >5,000 people
- Contains hazardous materials
- Is designated as essential facility
Reference: ASCE 7-22 Table 1.5-1
7. Comparison Query Workflow
Trigger: "What's the difference between..." or comparison questions
Process:
- Identify the two concepts being compared
- Create side-by-side comparison table
- Explain when to use each
- Provide examples
Example:
User: "What's the difference between LRFD and ASD load combinations?"
Response:
LRFD vs ASD Load Combinations (ASCE 7-22 Chapter 2):
| Aspect | LRFD (Section 2.3) | ASD (Section 2.4) |
|--------|-------------------|-------------------|
| **Full Name** | Load and Resistance Factor Design | Allowable Stress Design |
| **Also Called** | Strength Design | Working Stress Design |
| **Load Factors** | Higher (1.2D, 1.6L, etc.) | Lower (1.0D, 1.0L, etc.) |
| **Philosophy** | Factor loads up, factor resistance down | Unfactored loads, reduced allowable stress |
| **Basic Combo** | 1.2D + 1.6L | D + L |
| **Wind Combo** | 1.2D + 1.0W + L + 0.5(Lr or S) | D + 0.75L + 0.75(0.6W) + 0.75(Lr or S) |
**When to use:**
- LRFD: Modern codes, steel (AISC 360), concrete (ACI 318)
- ASD: Older codes, wood (NDS), masonry, aluminum
**Key Difference:**
LRFD combinations produce higher loads (factored up), intended for use with factored resistance equations.
ASD combinations use service loads, intended for use with allowable stress values.
You CANNOT mix them - use LRFD loads with LRFD resistance, ASD loads with ASD resistance.
Reference: ASCE 7-22 Sections 2.3 and 2.4
8. Procedure Query Workflow
Trigger: "How do I...", step-by-step questions
Process:
- Identify the design procedure requested
- Outline step-by-step process
- Reference relevant sections
- Provide decision points and checks
- List required inputs
Example:
User: "How do I perform equivalent lateral force seismic analysis?"
Response:
Equivalent Lateral Force (ELF) Procedure per ASCE 7-22 Chapter 12.8:
**Step 1: Verify ELF Method is Applicable (Section 12.6)**
- Check building height limits (Table 12.6-1)
- Check for structural irregularities (Tables 12.3-1, 12.3-2)
- Some systems/heights require modal analysis instead
**Step 2: Determine Seismic Parameters (Chapter 11)**
- Risk Category (Table 1.5-1)
- Site Class (Chapter 20)
- Spectral values SDS and SD1 (Section 11.4)
- Seismic Design Category (Section 11.6)
**Step 3: Calculate Seismic Response Coefficient Cs (Section 12.8.1.1)**
Cs = SDS / (R/Ie) [Eq. 12.8-2]
Subject to limits:
- Maximum: Cs = SD1 / [T(R/Ie)] [Eq. 12.8-3]
- Minimum: Cs = 0.044SDSIe ≥ 0.01 [Eq. 12.8-5]
**Step 4: Determine Approximate Period Ta (Section 12.8.2.1)**
Ta = Ct × hn^x [Eq. 12.8-7]
Where Ct and x are from Table 12.8-2
**Step 5: Calculate Seismic Base Shear V (Section 12.8.1)**
V = CsW [Eq. 12.8-1]
Where W = effective seismic weight
**Step 6: Distribute Vertical Forces (Section 12.8.3)**
Fx = CvxV [Eq. 12.8-11]
Where Cvx from Eq. 12.8-12
**Step 7: Check Story Drift (Section 12.12.1)**
Δ < Δa (allowable story drift from Table 12.12-1)
**Required Inputs:**
- Building geometry (height, floor areas)
- Dead loads (seismic weight W)
- Structural system (determines R, Ω0, Cd)
- Site seismic parameters (SDS, SD1)

Response Quality Checklist
When responding to ASCE 7 queries, ensure:
✅ Cite Equation Numbers: Always include equation numbers (e.g., "Eq. 12.8-1") ✅ Cite Section Numbers: Reference specific sections (e.g., "Section 12.8.3") ✅ Include Units: Always specify units (psf, mph, g, kips, etc.) ✅ Clarify Scope: Remind users ASCE 7 is for loads, not member design ✅ Check Applicability: Verify method applies to user's situation ✅ Provide Context: Explain when/why to use specific provisions ✅ List Assumptions: State any assumptions made in calculations ✅ Link Chapters: Cross-reference related chapters (e.g., Ch 11 → Ch 12)
ASCE 7 Special Considerations
1. Loads vs. Design Distinction
CRITICAL: Always clarify to users:
"ASCE 7 determines LOADS (forces) to apply to structures. It does NOT design members.
For member design, use:
- Steel: AISC 360
- Concrete: ACI 318
- Wood: NDS
- Masonry: TMS 402"
2. Load Combination Selection
Users often confused about which combinations apply. Always:
- Ask about ALL loads present (D, L, Lr, S, R, W, E, H, etc.)
- Ask design method (LRFD or ASD)
- Check for special loads (flood, ice, seismic detailed)
- Use
load_combinator.pyto generate full list
3. Seismic Design Flow
Seismic design has dependencies:
Risk Category (Ch 1) →
Site Class (Ch 20) →
Spectral Values (Ch 11) →
SDC (Ch 11) →
Structural System Selection (Ch 12) →
Analysis Method (Ch 12) →
Design Forces (Ch 12) →
Member Design (AISC/ACI/etc.)
Always guide users through this flow.
4. Wind Load Complexity
Wind loads have multiple procedures:
- Method 1: Simplified (limited applicability)
- Method 2: Analytical (most common)
- Method 3: Wind tunnel
- Method 4: Directional with regional data
Ask about building characteristics to determine applicable method.
Error Handling
Missing Information
If user query lacks required information:
"To determine [X], I need:
- Building height
- Risk Category
- [Other required inputs]
Please provide these details."
Out of Scope
If query is about member design, not loads:
"ASCE 7 provides the loads, but member design is covered by:
- Steel: AISC 360
- Concrete: ACI 318
Would you like help determining the loads per ASCE 7, or do you need assistance with member design?"
Ambiguous Query
If unclear what user wants:
"I can help with several aspects of [topic]:
1. Load calculation procedure
2. Load combinations
3. Formula lookup
4. Definition/terminology
Which would be most helpful?"
Common User Mistakes to Correct
- Mixing LRFD and ASD: Gently correct and explain difference
- Confusing loads with design: Clarify ASCE 7 scope
- Wrong Risk Category: Help determine correct category
- Incomplete load combinations: Ensure all applicable loads included
- Wrong exposure category: Ask about surrounding terrain
- Ignoring special loads: Check for flood zones, high seismic, etc.
