Topic 14: Stability analysis of structures. General and local stability
Topic 14: Stability analysis of structures. General and local stability

We would like to invite you to take part in research and practice seminar «Innovative methods of design of buildings and structures» on the 24th of May, 2016 at R. Gamzatov National library of Republic of Dagestan (43 Rasul Gamzatov Ave, Makhachkala).

- Added export of architectural model to ifc format which leads to two-way interaction with Tekla Structures
- OpenGL version has been updated to 3.3 for new rendering algorithm of design model. Thereby, operations with large-scale models became even simpler and faster
- For cross sections analysis considering bending torsion, there was added 5 new loading types, utilized in model feature 7. Added an opportunity to perform displacements unification by W (warping) for model feature 7. Bending torsion may have a significant influence on steel thin-walled bars of open profile, such as I-beam (symmetrical or asymmetrical) and channel bar. Bending torsion comes with bending of certain parts of cross section. For example, horizontal bend of each flange in opposite directions takes place during torsion of I-beams (with vertical web and horizontal flanges). Two oppositely directed bending moments form flexural-torsional bimoment, and its value defines bending torsion
- In results conversion mode, there has been added a consideration of architectural elements, so users can promptly pass out to other software not only geometry changes, but cross sections changes, that were passed out manually earlier
- Significantly expanded steel gauge database, added more than 20 new gauges

The new release of software package for structural modeling and analysis using finite element method (FEM) has been released – SP LIRA 10.4 R3.0

- Added independent from interface language option to select documentation language (reports, tables of input data and calculation results).
Extended Help
- Several additions and updates to the Help system were made;
- Added tutorial «Exercise 10 - Analysis of the structure on elastic foundation using Soil Editor».
