FAQ
Which codes are supported?
EN 1993-1-1, SP 16.13330.2017 and AISC 360-22; GOST, EN and AISC section ranges.
What is GMNIA?
Geometrically and materially nonlinear analysis with imperfections: includes plasticity per the steel diagram, flexural and lateral-torsional buckling and gives the ultimate load.
Can results be exported?
Yes: PDF, Word (DOCX) and Excel (XLSX) reports with inputs, intermediate values, diagrams and checks.
