LIRA-SAPR 2022 R2 Update 3 Release Notes

Plug-in for Tekla Structures: restored option to update the cross-sections according to results of FEA, selection/check of steel cross-sections.

Enhanced export from Revit to LIRA-SAPR: plates, openings and loads with curved contour segments.

Enhanced IFC import, namely:

• import of wall snaps;

• recognition of beam cross-sections;

• recognition of column cross-sections;

• fixed bug in recognition of the space elevation;

• recognition of stairs and conversion of prisms into stairs is modified.

Fixed bug in IFC export that caused the application to fail in some cases.

Export from DWG is improved. When the "Section only" option is active for a section, stairs are no longer exported when exporting to DWG if they are not included in the section.

Enhanced option to copy storeys from one project to another.

Restored option to display the "Offset" parameter for beams in the "Properties" dialog box.

Enhanced algorithm for generation of punching shear contours for columns with a section rotated on plan.

Added check for the method of generation - "Rectangle". Now the object is not generated if two sides of the rectangle coincide.

Improved transfer of plates from VISOR-SAPR module to SAPFIR module (plates restored from the design model to physical model).

Account for the volume of capital and column base when calculating the concrete volume in columns.

Enhanced generation of bar analogues of partitions for walls with a large number of openings of different heights.

The "Fill pattern for opening" dialog box is modified.

Fixed bug in displaying reinforcement in 3D view.

Fixed bug: the load applied through the slab properties did not take into account the opening in slab.

Fixed bug: deleting the links between nodes in the algorithm saved to the SAPFIR library.

Enhanced work of GridWall node. Now triangulation is taken into account when the wall is copied by storeys.

Triangulation by nodes is improved.

Modified node for generation of grid lines from the underlay.

Modified nodes for import of IFC and XLS.

Fixed bug in nodes for load generation when load values should be obtained from tables via ImportXLS node.

Fixed bug in the ImportIFC node when trying to update it.

Fixed: possible bug when opening the *.lir files for problems that contain deleted but not packed elements in which dynamic masses were defined.

To copy the node properties, the "Copy for selected objects" command is restored in the "Information about node" dialog box.

Fixed a possible bug in solver; it occurred when the number of specified assemblage stages was large (more than 300 stages).

Fixed bug in transferring of SAPFIR models that contains composite (steel & reinforced concrete) cross-sections.

The calculation of bimoment Bw is clarified for the 3D bar with account of the warping of the section (FE type 7).

In the SOIL system, modified option to assign properties for the layer of soil cushion (constructed soil).

Corrected option to select transverse reinforcement in analysis on fire resistance for DBN B.2.6-98:2009.

In the calculation of pile stiffness, the pile parameter "exclude offset length from pile length" is corrected.

For FE 265, 266, the stiffness description is restored to output the correct value for a specified clearance.

When the DCL table is generated by SP RK EN 1990:2002+A1:2005/2011, the possible failure of the program is eliminated when creating the main combination that contains wind and snow types of loads.

Methods for importing files and generating the output data in CSV format are added to LIRA-FEM API.

Modified: option to account for ultimate inelastic strain when transferring DCF forces to the analysis of steel joints. Previously, the reduction factor was not taken into account when there were less than two components as a result of the earthquake analysis by KMK 2.01.03-19.

Fixed bug: failure of application when trying to configure coupling of built-up profiles of channel and channel+I-beam types.

Corrected: possible failure of the application when calculating parameters of nonlinear cracks in RC plates in which the reinforcement in the plate cross-section is defined using multi-component types of PR (pilot reinforcement).

The stiffness of the FE 310 and stiffness of the steel rope is now updated when diameter of the rope is modified.

Restored: stability analysis for thin-walled shapes (thickness less than 4 mm) by DBN B.2.6-198:2014.

Corrected: output of mosaic plots for utilization ratio in buckling of steel beams and columns.

Partial safety factor Yc is taken into account in calculating the load-bearing capacity of driven piles in pullout load.

For RC bars, correct presentation of values on the mosaic plot for reserve factor of reinforcement in the "Reserve factor/Additional reinforcement (RF/AR)" check mode, as well as the output of values in the "Reinforcement in elements" tables.

Clarified computation of the stress strain state in iterative nonlinear solids with the specified concrete and reinforcement.

For SP RK EN 1992-1-1:2004/2011, corrected the error in calculating the reserve factor for reinforcement in plate elements when the acting forces from shear loads are less than the load-bearing capacity of concrete section.

The restriction on the number of soil layers defined in the "Boreholes" dialog box of the SOIL system is removed.

Corrected documentation in the "Boreholes" input data table for the case when the numbering of boreholes does not start with "1".
