EngiCalcX automates the modeling layer of structural engineering — translating project parameters into a fully configured FE model, executed directly within your SAP2000 or STAAD.Pro installation.
Enter geometry, loads, and section properties — or describe your structure in plain English and let AI fill the form.
AI generates a complete, runnable script — nodes, members, sections, loads, and LRFD combinations included.
Run directly in SAP2000, STAAD.Pro, or OpenSees. Export reactions, forces, and displacements — print-ready reports included.
No install, no license key. Open a URL and start calculating from any device.
ACI 318-19, AISC 360-22, ASCE 7-22 — every output traceable to the standard clause.
Describe your structure in plain English or upload a drawing — AI fills the parameters.
Print-ready calculation sheets with all inputs, formulas, and step-by-step workings.
Engineering Tools
