Seismic Anchor Calculation Request Form
The PANACHE anchor calculation request form, now a live web form — no PDF to print or email. Submit equipment data once and receive a PE/SE stamped seismic anchor calculation per ASCE 7-22 Chapter 13 and ACI 318-19 Chapter 17.
Use this form for seismic anchor calculations, anchor bolt design, equipment anchorage design, and HCAI / OSHPD anchorage submittals. One form per equipment item.
What a stamped seismic anchor calculation package looks like
Below is a redacted three-page excerpt from an indoor switchboard anchor calculations report prepared for a data center project. Client, project and site information has been removed — the engineering content is unchanged so you can see exactly what the deliverable contains before you submit a request.



Sample excerpt only. Customer name, project name, site address and equipment tags are redacted; all Panache Engineering reports remain confidential to the client.

What happens after you submit the anchor calculation request
Every submitted request is reviewed by a licensed PE/SE. We confirm the governing code edition, derive the ASCE 7-22 §13.3 component seismic design force Fp (including Hf, Rμ, CAR, Rpo, and the Fp,min/Fp,max bounds), resolve per-anchor tension and shear from the equipment center of gravity, and check every ACI 318-19 Chapter 17 limit state — steel, concrete breakout, pullout, side-face blowout, and pryout — plus the §17.8 combined tension–shear interaction with the Ω0 over-strength amplification.
Which requests this form covers
Use it for a seismic anchor calculation, anchor bolt calculation, anchor bolt design, seismic anchorage calculations, equipment anchorage design, or an HCAI/OSHPD anchorage submittal tied to an OSP, OPM, or PCS pre-approval. Chillers, generators, air handlers, pumps, transformers, switchgear, tanks, and rack-mounted equipment are all handled through the same workflow.
Prefer to run the numbers first?
Try the free SDS, Ip & z/h calculator or the Fp calculator, review three worked anchor bolt design examples, or read the most common anchorage mistakes before submitting. Full service details are on the seismic anchor calculations page.

Seismic anchor calculation request FAQ
- How do I request a seismic anchor calculation?
- Complete the online seismic anchor calculation request form on this page — customer and project info, equipment weight and dimensions, code edition, seismic design criteria, and anchorage details. PANACHE ENGINEERING responds with a scope and fee, usually within one business day.
- What information is required for an anchor bolt calculation?
- Equipment weight Wp, plan dimensions and height, center of gravity, anchor hole pattern, concrete pad thickness and f'c, available edge distance, plus the site seismic parameters SDS, SD1, Site Class and importance factor Ip. If parameters are unknown, provide the site address and we run the ASCE hazard lookup.
- Which codes are the calculations prepared to?
- ASCE 7-22 Chapter 13 (2025 CBC) or ASCE 7-16 (2022 CBC) for the component seismic design force Fp, and ACI 318-19 Chapter 17 for anchor capacity — steel, concrete breakout, pullout, side-face blowout, pryout, and the §17.8 tension–shear interaction.
- How long does a stamped seismic anchor calculation take?
- Typical turnaround is 3–5 business days from receipt of complete equipment data. Expedited 24–48 hour review is available; select 'Expedited review requested' on the form.
- Do you provide calculations for HCAI / OSHPD projects?
- Yes. For California healthcare projects we prepare anchorage calculations tied to an OSP, OPM or PCS pre-approval, including the Certificate of Compliance and seismic certification label where required.
- Can you stamp calculations outside California?
- Yes — indicate the required state of PE stamp on the form. We hold licensure in multiple states and coordinate stamping for out-of-state projects.
- What does the stamped seismic anchor calculation package look like?
- A typical package includes a stamped cover sheet, the ASCE 7 Chapter 13 seismic coefficient derivation, per-anchor tension and shear from the equipment center of gravity, the ACI 318 Chapter 17 anchor check with the selected anchor, embedment and edge distance, and the anchor location plan. A redacted three-page excerpt of a real switchboard anchorage report is available on this page.
