STRUCTSOFT — The Complete Guide: Free 2D Frame and Truss Analysis in the Browser
STRUCTSOFT by ADIT analyses plane frames and trusses by the direct stiffness method, with three degrees of freedom per node. You define geometry, sections, supports and loads, and get reactions, moment, shear and axial force diagrams and the deflected shape — in the browser, in Hebrew or English, with no registration.
STRUCTSOFT — 2D Structural Analysis
ADIT Ltd (ADIT)
Plane frame and truss analysis in the browser — forces, displacements, diagrams and steel design.
Get it from the vendorWhat you get
- 44 ready templates — including 18 truss types, multi-span beams, multi-storey frames and arches.
- Section library — including non-prismatic members.
- Wind and seismic loads — generated to SI 414 and SI 413, with combinations to SI 412, EN 1990 and ASCE 7.
- Influence lines and moving loads — plus geometry import from DXF.
- Steel design — checks to EN 1993-1-1 with the governing utilisation per member.
Who it suits
Engineers and students working on plane structures who want load combinations to the Israeli standards and a full calculation report to attach to a submission. For three-dimensional structures you need a different tool.
