IFC - Industry Foundation Classes

  • Improved time of importing structural lines for larger IFC files. (234954)

Cross Sections and Materials#

Feature

  • SSD material definition for reinforcing steel: Definition for max. thickness defines the bar diameter which is used for the preset allowed stress range sig-dyn, default value 28 mm.

Bugfix

  • Sometimes the temperatures in cross sections were taken from the program HYDRA a little too high, e.g. for the hot design.

  • Sometimes an incorrect equivalent area (Bredt) was calculated if arches were part of the reinforcement. (234801)

  • The table of forces and moments from thermal effects was mixed with the table of forces and moments from prestressing.

  • SSD calculatoric stress-strain curve for concrete and reinforcing steel: For the default material definitions the default safety for the calculatoric stress strain curves is printed correct with 1.3 in the output.

  • A crash could occur when saving cutting results to the database.

  • The material number was not displayed in the warning for incorrect shear cuts.

  • Shear cuts did not work for cross sections that only contained circles.

Plastic Hinges & Performance Categories#

Bugfix

  • Various improvements and corrections for uniaxial bending hinges My and Mz, as well as the My-Mz interaction hinge.

  • Correction of the calculated rotation related to criteria within a performance category.

Pushover Analysis for Bridge Piers#

Bugfix

  • Correction of the processed criteria within a performance category for uniaxial bending hinges My and Mz, as well as the My-Mz interaction hinge.

General

  • MAXIMA: Definition of combinations, without their corresponding actions or load cases, marked as obsolete for future versions.

  • MAXIMA: Minor fixes and cleanup.

Shear Wall Design#

Bugfix

  • In the SSD Task ‘Capacity Check for Building Cores’, the My-Mz capacity curve plot sometimes caused an exception. To avoid this, the z-elevation is no longer plotted. (235311)

Design of Concrete Columns#

Feature

  • The columns that exceed the maximum permissible reinforcement ratio are now marked in the summary table.

Bugfix

  • For EN 1992-1-2 eq. 5.7 the correct limit for the effective length is now used. (234035)

Design of Concrete Beams#

Feature

  • It is possible to delete previous design group information and results via BDEL input.

Bugfix

  • It is possible to use superposition load cases from MAXIMA and self defined combinations in the same calculation.

  • A bug that shifted values in some tables has been fixed.

  • The default for the function moment smoothing is now correctly set.

Buckling Resistance of Steel Members#

Bugfix

  • The postprocessing of the eigenvalues has been improved, as in some rare cases Ncr could not be calculated, which resulted switching calculation to an analytical approach triggering a warning. (233646)

Life Cycle Assessment (LCA)#

General

  • The GWP values of the default mapping in the task Life Cycle Assessment and the used values in the Teddy examples have been updated according to the latest version of ÖKOBAUDAT.

Feature

  • When opening the task for the first time, the file path for the Excel export is now set as a dynamic path, so that the Excel file is per default saved in the project folder.

Interactive Pre- and Postprocessors#

Viewer#

Interactive System Visualization Tool

General

  • Various performance and stability improvements.

Feature

  • Added license information for projects created with a trial or educational license (feature also extended to System Visualization).

  • Filter the load case list by load case type.

  • Beam with translational hinge (N, Vy, or Vz): Added a thin line in the deformed state to emphasize the mechanical behavior.

  • Improved rendering of deformed beam for STAR2 load cases.

Bugfix

  • Fixed incorrect rendering of springs between two nodes: they were previously rendered as support springs.

  • Fixed a possible crash for beams with eccentricities in the deformed state.

  • The spring reference area was omitted when calculating the rendering spring size.

  • Load cases with pure rotations could not compute a meaningful default displacement factor.

Result Viewer#

Graphical and Tabular Post-Processing

Bugfix

  • A wrong group number could be displayed if the last group was invalid (has no elements). (235280)

Graphic#

Graphical Representation of FE Structures and Results

Bugfix

  • Sometimes moving springs were displayed incorrectly during the incremental launching.

  • Better visualisation of inclined bore profiles. (235107)

  • Sometimes double-clicking in the tree to open the dialogue did not work. (234518)

  • Sometimes a double redraw occurred after opening GRAPHIC.

  • GRAPHIC no longer asks for “Save” directly after starting a document. (226747)

FEA Modules for Batch Processing#

SOFiMSHC#

Geometric Modelling

General

  • Minor documentation update / clarifications.

Feature

  • Preserve prescribed nodes of slave area, when coupling the mesh topology of two areas (SARS). (234579)

Bugfix

  • Couplings generated at hinges (edge releases) between areas, via SARB FIX, were sensitive to modeling inaccuracies, in certain GUI-workflows, introducing analysis instabilities. This has been treated, so that possible modeling inaccuracies do not influence the system’s stability. Special couplings, introduced for this purpose in v2025-3, have been removed. (234657)

  • Corrected export of GUID, for SLNS and SARS records.

SOFiMSHA#

Import and Export of Finite Elements

General

  • Minor documentation update / clarifications.

Bugfix

  • Prevent rare crash when processing models with nodes that have been deleted from the system.

DECREATOR#

Generation of Design Elements

Bugfix

  • Length of design element corrected, when its geometry is based on a structural line which is created on a secondary axis on which the parametrization is scaled according to placement rotations. (233842)

  • When a design element is defined in SOFiPLUS with two end cross sections to interpolate from, the cross section ID at the last design section that was changed during analysis in SSD is now corrected. (234514)

  • When warnings related to automatic interpolation of cross sections are printed in the Calculation window, also clearly mark module name accordingly with exclamation mark in yellow. (234419)

Design of Plates and Shells

Bugfix

  • Fatigue design: Stress range of shear reinforcement: storage in database corrected.

  • The value Crdc according EN1992-1-1_6.2 is now taken from the boxed values of the .ini file and can so be changed. Special case Norway: there the .ini file sets 0.15, but usually the EN-condition allows 0.18. So the default for Norway is still 0.18. If you want to set 0.15 for Norway, please input 0.1501 for the boxed value. (234403)

  • Punching: in case a different beam cross section attached below and above a slab, BEMESS now takes into account the correct section for the tension/compression punching force. (235085)

  • Punching: edge columns with openings: correction of analysis of u-out in case of multiple stirrup rows. (234933)
