Static and Dynamic Analysis of Plane Frames with Linear and Non-Linear Capabilities
2D Structural Frame Analysis — Static and dynamic analysis of plane frames with linear and non-linear capabilities.
Overview
What is FRAME 2D?
FRAME 2D is a plane-frame analysis program from RUNET Software — marketed as FRAME2Dexpress — supplied and supported in India by RAM CADDSYS. It runs static and dynamic analysis of portal frames, multi-bay frames, continuous beams, trusses and grillages, with loads combined per Eurocode 1. The FRAME2Dexpress + EC Design edition adds member design to Eurocode 2, 3 and 5, with reports exporting to Word and PDF.

Applications
Portal and Multi-Bay Frame Buildings
Analysis of steel or concrete portal frames and multi-bay building frames for moments, shears, and deflections under dead, live, and combined Eurocode load cases.
Trusses and Mixed Frame-Truss Systems
Modelling of trusses and frames containing tension-only members and hinged connections within a single 2D model.
Continuous Beams and Grillages
Static analysis of continuous beams and 2D grillage systems, including support reactions and force/displacement diagrams.
Eurocode Member Verification
Designing and checking reinforced-concrete, steel, and timber members of the analysed frame to EC2/EC3/EC5 in the EC Design edition.
Dynamic Characterisation of Frames
Determining natural frequencies and mode shapes of frame structures for vibration assessment and dynamic understanding.
Engineering Documentation
Generating code-referenced calculation reports in Word and PDF for design submissions, peer review, and project records.
Design Codes
Supported codes and standards
EN (Eurocode)
Eurocode 0 (EN 1990)
basis of design / load combinations

Calculation results and reports can be exported to Word format for editing and documentation.
PDF export
Reports and output can be exported directly to PDF for distribution and archiving.
Compare
FRAME2Dexpress vs FRAME2Dexpress + EC Design edition
Both editions share the same static and dynamic frame-analysis engine — the EC Design edition adds Eurocode member design on top.
| Criterion | FRAME2Dexpress | FRAME2Dexpress + EC Design |
|---|---|---|
| Scope | FRAME2DexpressStatic and dynamic (modal) analysis of the 2D frame — internal forces, displacements, natural frequencies, mode shapes | FRAME2Dexpress + EC DesignStrength: Everything in the base edition, plus Eurocode member design |
| Load combinations | Strength: Eurocode 1 combinations with user-defined coefficients | Strength: Same Eurocode 1 combinations, carried into the design checks |
| Code checks | None — analysis results only | Strength: Eurocode 2 (concrete, incl. second-order column effects), Eurocode 3 (steel, incl. buckling), Eurocode 5 (timber) |
| Report output | Displacement, force, and mode-shape diagrams in Word/PDF | Strength: Same diagrams plus Eurocode clause-referenced design calculations in Word/PDF |
Choose the base edition for pure analysis; add EC Design when the same model must also produce code-checked member sizes.
