What's in every stamped seismic anchor calculation
Whether your project documents call it a seismic anchor calculation, an anchor seismic calculation, or a seismic anchorage calculation, you receive the same PE/SE stamped deliverable — code-current, plan-check ready, and built to clear HCAI, DSA, and IBC review on first submission.
- Fp / Fv determination per ASCE 7-22 §13.3
- Per-anchor tension & shear from free-body analysis
- Ω0p amplification for concrete-controlled limit states
- ACI 318-19 Ch.17 — steel, breakout, pullout, blowout, pryout
- §17.8 tension–shear interaction with DCR table
- Cracked / uncracked concrete assumptions documented
- Edge distance & spacing modifications (ψed, ψc)
- PE/SE wet stamp on every sheet
Code references on every page
Every seismic anchor calculation we deliver cites the governing code section for each check — no black-box outputs, no proprietary spreadsheets without traceability.
| Code Section | What it governs |
|---|---|
| ASCE 7-22 §13.3.1 | Fp horizontal seismic force on nonstructural components |
| ASCE 7-22 §13.3.2 | Fv vertical seismic force component |
| ASCE 7-22 §13.4.2 | Ω0p overstrength amplification for anchors in concrete/masonry |
| ACI 318-19 §17.5 | Steel strength of anchor in tension & shear |
| ACI 318-19 §17.6 | Concrete breakout strength (Ncb / Vcb) |
| ACI 318-19 §17.7 | Pullout, side-face blowout, pryout strengths |
| ACI 318-19 §17.8 | Combined tension & shear interaction |
| ACI 318-19 §17.10.6 | Seismic 0.75 reduction on concrete-governed strength |
