Structural engineering software LIRALAND Group
The update delivers improvements to IFC import, model and load processing, enhanced interaction algorithms, and higher calculation accuracy. New geometry-editing tools have been added, Ukrainian steel tables for 2025 have been updated, stability has been improved, and multiple critical issues across LIRA-CAD, LIRA-FEM, and related modules have been fixed.
Modifications have been made to the functionality of creating and editing models, which contribute to improved accuracy. Configuration of calculation parameters and performance improvements. Integration of new algorithms. Bug fixes, comprehensive enhancement of the interface, security, and overall performance.
Updated features and options: new graphic engine, RC Expert, plate analogues, analysis on explosion, drawings, centre of masses, tunnel, crack, project template, cable-stayed structures, rope, plate, lift pit, mass condensation, unification, PRB, impulse, DBN B.1.2-2006, piles, shaft, calculation of settlements, EN 1997-1:2004, orthotropy of the shape, equivalent section, structural failure, erection process, EN 1991-1-4, stiffness of restraints, earthquake, damping, modal masses, displacement of nodal masses, transferring of accelerogram, vertical acceleration, nonlinear hinges, load on fragment, EN 1993-1-1:2005/AC:2009, stress diagrams, mosaic plots of analysis results, stiffness of the floor slab, DBN B.2.6-98:2009, tracing routine, EN 1992-1-1:2004/А1:2014, heat flow, etc.
