LIRA-CAD

  • Fixed error when editing opening contour in load specified across the area.

  • Corrected load application from spaces containing openings. Previously, loads were applied to the centre of the opening.

  • Eliminated duplication of loads on stair stringers.

  • Resolved potential issues when generating meshed model containing Prism objects.

  • Fixed error in subdivision of inclined columns by storey levels. Generated columns were shifted from the original central axis of the column.

  • Fixed error in retrieving parameter M_FEA_BARRA_FORM via API.

  • Fixed saving of plate intersection search tolerance. The specified value was previously reset after each update of meshed model.

  • Corrected assignment of load to erection stages. Loads intended as post-erection were incorrectly included in erection stages.



LIRA-FEM

  • Fixed potential crash in SOIL system when model contained permafrost soil properties.

  • Fixed an issue where the application could become unresponsive during iterative calculation of elastic foundation parameters C1/C2 in models with ten or more dynamic load cases.

  • For problems with account of erection stages, corrected consideration of load combination factors when generating design combinations of loads for punching shear.

  • When generating the results table "Load on fragment" in problems with nonlinear load histories, generation of history names is corrected.

  • For steel built-up sections, eliminated discrepancies between ULS results in batten plates in analysis by elements and by individual design sections.

  • Clarified application of safety factor ɣn defined in DCF and DCL parameters when determining punching shear design forces.

  • Fixed generation of forces for steel joint design by DCF when normative loads are defined in the model.

  • For L-shaped reinforced concrete sections, eliminated discrepancy in coordinates of defined reinforcement bars calculated in the main model and in the local mode of reinforcement.
