Update 1 for LIRA-FEM 2024 R2

Last updated: April 18, 2024

For nonuniform loads created as a load on a group of bars or plates, the correct load type is transferred to the solver (the bug appeared only in LIRA-FEM 2024 R2). This bug led to an incorrect calculation of load intensity.

  • Fixed bug: in the calculation of compensating loads by Qx and Qz for the 3-node FE of the joint (FE 258). This situation may cause residual errors in the solution during iterative calculation.

  • In the SOIL system, the subsidence deformations are not considered for collapsible soils if the initial subsidence pressure Psl is higher than the total stress P.

  • Clarified generation of contour plots for C1 modulus in case subgrade modulus is calculated by Method 6.

  • Fixed bug: in updating the list of STC materials when the elements are selected.

  • Fixed: an inaccuracy when generating the response spectrum for the dynamic load Accelerogram (dynamic module 27).

  • Fixed: a possible error in generating the text tables with the results by DCL with a large number of DCL combinations.

  • Fixed bug: in saving the *.lir file for problems where nonlinear load histories and DCF calculation are defined.

  • Fixed bug: in presentation of measurement units for a specified Req in the Pile Groups dialog box.

  • Clarified analysis of reinforcement by serviceability limit state.

  • Fixed bug: in calculating DCF for punching shear contours when normative loads are used in the design model.

  • Fixed bug: design model of a beam was generated outside the physical model.

  • Fixed bug: program failure when generating the design model.

  • Fixed bug: it was impossible to generate a slab with the Ellipse method for generation.

  • Fixed bug: it was impossible to modify Parameters of opening when a group of objects was modified.

  • Fixed bug: inconsistency between assemblage stages when transferring from LIRA-CAD module to VISOR module in the LIRA-FEM software.

  • Fixed bug: in displaying the beam system in physical representation of the model.

  • Fixed bug: possible program failure in the Library of joints dialog box.
