AutoCalcs

AutoCalcs is a browser-based 3D structural finite element analysis and steel design program. It lets structural engineers model trusses, frames, plates, and shells and run linear static, P-Delta (second-order), elastic buckling, and modal (natural frequency) analysis, including tension- and compression-only members. Integrated member design checks cover AISC 360-16/22, Eurocode 3 (EN 1993-1-1), AS 4100:2020, and CSA S16:19. No installation is required: open https://autocalcs.com/structuralfea and start modelling. A free tier is available; Pro adds cloud storage, higher limits, and report export.
