SOFiSTiK Structural Desktop#

Design Codes#

General

  • DIN FB102-2009 / DIN FB104-2009: Default value for maximum tan(θ) is now 1.0 (boxed value TANMAX), corresponds to a minimum cot(θ) 1.0.

  • CSA S6-19: Modification of the action C - is now similar to C in the Eurocode with PART P SUP PERM.

IFC/SAF Data Exchange#

General

  • IFC Import: Reading model now continues without fatal errors in cases of empty optional attributes and long integers such as timestamps.

Cross Sections and Materials#

Bugfix

  • The reference points of CDS profiles were incorrect.

  • The detailed output via ECHO SECT did not worked. (236750)

  • Missing materials were not checked when calculating the shear reinforcement in standard cross-sections. (236831)

  • Sometimes the position of reinforcement points and stress points in thin-walled elements was not detected correctly. (236734)

Moving Load Train Analysis#

Bugfix

  • The train loads were not applied correctly when the geometric axis (reference line) selected for the load application was referenced by structural lines that were overlapping one another. This has been fixed.

  • FEABENCH: In case of an eccentric shell element with orthotropic thicknesses spurious moments due to eccentricities were introduced. The issue has been fixed. (237008)

  • FEABENCH: In case of shell elements with orthotropic behavior introduced using sectional values the thickness for shear action is now derived from the actual sectional area (previously the shear area of the section was used). (237008)

Combinations and Superpositions#

General

  • MAXIMA: Performance of the combination tracer has been improved, computation time significantly reduced.

Bugfix

  • MAXIMA: Fixed bug in combination tracer (TRAC), when processing results on the left / right of a cross-section and non-contributing load cases have been filtered out.

Design of Concrete Columns#

Bugfix

  • The calculated amount of reinforcement was not shown in the list of all columns in the task ‘Column Design Assistant’.

Design of Concrete Beams#

Bugfix

  • In some cases, globally defined load case combinations and the type of load cases were not recognised correctly. (236629)

  • Fixing of the default value for the factor with which a load case is processed in the BEAM module.

Design Checks for Composite Cross Sections#

Feature

  • Envelopes of the results for all load cases of a task (e.g. maximum or minimum stress in the material) can be stored with the command RENV.

  • It is now also possible to explicitly set the material safety factors for the ultimate limit state design checks with the command GAMA.

  • The computation time has been significantly reduced for certain cases where the calculation of stresses required much time. (232761)

Bugfix

  • The calculation of the minimum reinforcement (TASK MINR) for the limitation of the crack width was always done using a crack width limit of 0.2 mm and did not always use the decisive resp. largest bar diameter in the concrete element. (236734)

  • For control of cracking due to direct loading (TASK CRAC) the limit stresses based on the bar diameter were not correct for the crack width limit of 0.3 mm.

  • The calculation of the shear forces for the design of the shear connection (TASK BOND) did not reset the stiffness of the concrete to the original value of the concrete type. This has been enabled now to always calculate the shear forces based on the uncracked cross-section (also for sections modeled with reduced elastic modulus of the concrete).

Life Cycle Assessment (LCA)#

Feature

  • The Excel file generated by the calculation of the Life Cycle Assessment can now be opened directly via the context menu of the task.

Bugfix

  • Several adjustments for the export of LCA results to Excel:

    • Update of the Excel template file to fix some issues.

    • In some cases the export of design elements had to be corrected.

Interactive Pre- and Postprocessors#

Viewer#

Interactive System Visualization Tool

General

  • Improved overall performance and application stability.

Feature

  • Added visualization of design elements.

Bugfix

  • Fixed a potential infinite synchronization loop.

  • Resolved an issue where beams could appear with incorrect colors after loading a view.

  • Fixed duplicate synchronization when rendering the model in a deformed state.

Result Viewer#

Graphical and Tabular Post-Processing

Bugfix

  • Reinforcement stress with tension stiffening in concrete from the COMPOSITE programme was not calculated with reduced Young’s modulus.

Graphic#

Graphical Representation of FE Structures and Results

Bugfix

  • Sometimes the group selection of split structural lines did not work. (236157)

  • Sometimes invalid utilisation levels on design elements were displayed incorrectly.

  • Sometimes single input loads were not displayed.

  • Sometimes input loads on structural lines were not displayed. (236723)

  • The picture numbers in the GRA file (“AND POSI…”) were incorrect if more than one layer was in a picture. (236544)

  • The VIEW definition in reference of split structural lines did not work. (236480)

  • GRA file: The changes for colours of structural areas were not saved. (236724)

  • GRA file: The definition of visibility of placements was not saved correctly. (237466)

FEA Modules for Batch Processing#

SOFiMSHC#

Geometric Modelling

General

  • Updated export of support conditions / couplings of structural lines.

  • Improved definition of secondary groups that are automatically created for Storeys / Towers.

Bugfix

  • Fixed minor problem in processing structural lines.

SOFiMSHA#

Import and Export of Finite Elements

General

  • Improved definition of secondary groups that are automatically created for Storeys / Towers.

DECREATOR#

Generation of Design Elements

Bugfix

  • Integration of forces from quad elements is now corrected when the design element’s x-axis is inclined relative to the local-z axis of quad elements. (235862)

CSM#

Construction Stage Manager

Bugfix

  • Fatigue check: factor for static determined and undetermined part of prestress corrected for DIN and OENORM. (233849)

ASE#

General Structural Analysis of FE Structures

Bugfix

  • Halfspace HASE max. pressure limit DPDS corrected in case of vertical cellar walls. (236622)

  • Nonlinear quad cracked concrete: calculation of crack with on centric tension corrected – no effect on other results . (236460)

AQB#

Design of Cross Sections

Bugfix

  • Improved handling of warnings, where in rare cases, the warning was not printed correctly or was missing if iteration failed. (234706)

  • The option of setting cot(θ) < 1.0 has been provided, as DIN FB allows the use of cot(θ) < 1.0 in exceptional cases. (235206)

BEMESS#

Design of Plates and Shells

Bugfix

  • Punching for OENORM corrected in case of more than 2 stirrup perimeters.

  • Crack width analysis: storage for program Graphic improved in case of not exact calculated crack width for CTRL LAY 1. (236877)
