The app intentionally separates rapid concept exploration from final code-specific professional design.

DMAC Structural Frame Designer is provided for education, preliminary studies, concept development, option comparison, workflow support, and engineering training. It is not a licensed engineering service, design certification, sealed calculation package, construction document, code-compliance determination, or substitute for the professional judgment of a qualified and appropriately licensed Professional Engineer (PE), Structural Engineer (SE), architect, geotechnical engineer, specialty engineer, or other responsible design professional.
All calculations, member suggestions, layouts, optimization results, quantities, load paths, deflections, vibration indicators, connection heuristics, reinforcement arrangements, redundancy scores, and other outputs are approximate unless independently verified. Built-in section properties and resistance models are illustrative/preliminary and may be incomplete, simplified, outdated, jurisdictionally inapplicable, or inconsistent with project-specific codes and specifications. Users must independently verify geometry, units, loads, load combinations, boundary conditions, material properties, stability, buckling, fatigue, fire, seismic, wind, snow, vibration, robustness, progressive collapse, connection design, constructability, temporary conditions, foundations, detailing, durability, and every other applicable requirement.
The user is solely responsible for selecting the governing codes and standards, confirming current editions and local amendments, validating all inputs and outputs, obtaining required professional reviews and approvals, and ensuring that final engineering work is prepared, checked, signed, and sealed where required by law. The app must not be relied upon for emergency decisions, field acceptance, construction authorization, demolition, temporary works, shoring, erection sequencing, or any condition where failure could cause injury, death, property damage, environmental harm, or economic loss.
No warranty is made regarding accuracy, completeness, fitness for a particular purpose, merchantability, non-infringement, availability, or suitability. To the maximum extent permitted by applicable law, Channer McKenzie Inc. and the software authors disclaim liability for losses, damages, claims, delays, design errors, omissions, construction defects, professional liability, or consequential damages arising from use of or reliance on the app. If any provision of this disclaimer is unenforceable in a jurisdiction, the remaining provisions continue to apply to the fullest extent permitted by law.
By creating an account or continuing to use the app, the user acknowledges these limitations and agrees to use all results only as preliminary support subject to independent professional verification.
