The standard applies to the design of:
It covers the structural design of the stack shell, base plate, anchor bolts, and internal components like platforms and liners. It does not cover the design of the foundation itself (which is typically governed by ACI or other standards) but dictates the loads the foundation must resist.
The document is typically organized into the following sections:
If your firm regularly uses ASME codes (BPVC, B31.1, STS-1), a subscription to the ASME Standards Collection provides unlimited PDF access for a flat annual fee (starting around $4,500/year for up to 10 users).

| Chapter | Title | Key Formula/Table | |---------|-------|-------------------| | 4 | Loads | Wind, seismic, ice, thermal | | 5 | Stress Design | Allowable stress vs. load factor design | | 6 | Wind Load Analysis | Vortex shedding period (Eq. 6-14) | | 7 | Dynamic Response | Damping coefficients (Table 7-2) | | 12 | Foundations | Anchor bolt and base plate design | | 14 | Fabrication & Welding | Preheating requirements (Table 14-1) | | Appendix C | Liner Support | Friction vs. guided supports |
Pro Tip: Use the PDF’s search function to jump to "corrosion allowance" (typically 1/16" to 1/8" based on flue gas temperature) or "sampling ports" (EPA Method 1 locations).
Materials selection and allowable stresses

Supports, attachments, and ancillary items
Documentation and traceability
Marking and labeling
Before the widespread adoption of ASME STS-1, steel stacks were often designed using generic structural steel codes that did not account for the unique dynamics of tall, slender chimneys. Key risks include: It covers the structural design of the stack
The ASME STS-1 standard solves these problems by providing unified, prescriptive, and performance-based design pathways. It is referenced by OSHA (for safety during erection), the EPA (for emissions sampling ports), and local building codes.
