STRUCTSOFT is free software for static analysis of 2D structures — frames, trusses, arches and multi-storey buildings — by the direct stiffness method, right in the browser and with no registration. You get reactions, internal forces, moment, shear and axial diagrams, the deformed shape and steel checks to EN 1993-1-1.
Why it stands out
- Dozens of ready templates — every common truss type (Pratt, Warren, Fink and more), frames, arches and multi-storey buildings, each with its own settings panel and live preview.
- Israeli standards built in — load combinations to SI 412 (2023), wind to SI 414 and seismic loads to SI 413, alongside EN 1990 and ASCE 7.
- Almost 1,000 sections — IPE, HEA, HEB, UPN, angles, hollow sections, cold-formed and tapered sections, with properties computed from the geometry.
- Built-in verification — every report runs 16 checks against closed-form solutions, and the program has also been compared with commercial software and with an independent open-source program; against anaStruct it gave the correct answer for hinged frames too.
- Influence lines, moving loads and DXF import, with a full calculation report.
