New LIRA 10.10 R1.1 version has been released

New LIRA 10.10 R1.1 version has been released
1/20/2020
Dear colleagues, we're informing about official release of a new SP LIRA 10.10.

Release 1.1 contains corrected detected errors and some changes and additions.

SP LIRA 10.10 R1.1 is available for downloading in download section.

Licence holders of SP LIRA 10.10 can update to 1.1 version for free.

Design and graphical environment
  • Refined algorithm for physically nonlinear plate elements (FE 542 - 547)
  • Refined algorithm for plate elastic link FE (94, 97)
  • Implemented calculation of mean settlement in "Tilts and twists" mode
  • Implemented visualization of complete linear and angular displacements in the form of mosaics and isofields
  • Implemented possibility of consideration bedding shear coefficients (for bar and plate elements) in the form of Сx,y = mu*C1z
  • In the "Load Analysis" mode, the calculation of projective loads on elements has been clarified
  • In the module for calculating seismic effects (56), according to the requirements of SI 413 (Israel), change 5 from 12.2013 is taken into account
  • Fixed visualization of internal forces diagrams in the bar elements from DCL in the problems of the ASSEMBLAGE system
  • The bug leading to the crash of the program when using the "Variation of models" module is fixed
  • Fixed a bug leading to the unwarranted addition of empty element groups
Steel structures
  • Refined algorithm of cross sections checking in accordance to Eurocode
  • Refined calculation of stiffness properties of cross sections made of paired angles
Soil
  • Amendment 2 to paragraph B.6 of SP 24.13330.2011 was implemented - the values of the bed coefficient cz on the side surface of the pile are determined taking into account changes in the values of the proportionality coefficient K (Table B.1) and the coefficient of working conditions γcz
  • The characteristics of soils in the soil editor have been clarified, depending on the choice of regulations and the method of foundation construction (slabs / piles)
  • The interface for initial data input is changed depending on the selected regulations for calculation of the single pile characteristics
Import/Export
  • For import from Revit:
    • 1. Fixed determination of geometric properties of parametric cross sections;
    • 2. Refined algorithm of bar's local axes import;
    • 3. Added consideration of seismic loading state;
    • 4. Refined consideration of loads in wind loading states.

  • Updated Help system
