Dear colleagues, we're informing about official release of a new SP LIRA 10.10.

Release 2.2 contains corrected detected errors and some changes and additions.

SP LIRA 10.10 R2.2 is available for downloading in download section.

Licence holders of SP LIRA 10.10 can update to 2.2 version for free.

Graphics system and computational processor
  • Updated changes #1 for SP 14.13330.2018 В«SMiP II-7-81* Construction in Seismic AreasВ» (65 dynamics module)
  • Fixed an error in the multinode elements of flat soil when calculating the filtration, refined calculation of filtration velocity
  • Introduced corrections for the addition of seismic action forms in the 51 (formula 9) and 61 (formula 5.9) modules
  • Improved 44 dynamics module according to EN 1998-1:2004 (Eurocode 8), added the option "Extend the graph for the components of the elastic spectrum with values, as for T = 4sec."
  • Implemented NTP RK 08-01.1-2017, as national annex to the 44 dynamics module according to EN 1998-1:2004 (Eurocode 8)
  • Restored assemblage with geometrically nonlinear elements
  • Fixed summation of displacements in the generalized loading
  • Corrected the work of FE 207 and FE 208 (delivery message about rope breaking and solving a problem in the presence of a small number of iterative equations)
  • Refined consideration of loading states concurrent to constant loading state in the DCF
  • Fixed display of results by combinations in special elements
  • Kazakhstan's standards for wind and snow loads have been implemented
Reinforced concrete
  • Refined algorithms of cross sections' proportioning/checking on complex torsion
