Release notes

Overview of the published InfoCAD program versions

Version 23.1.1 – 19 September 2023
The design check program could abort in certain cases with the error 'Filename.fem contains an unexpected object'.

Version 23.1 – 21 August 2023

In the shear joint check, the strain state could not be determined in certain cases. The 'Last combination' command incorrectly reported an incompatibility in certain cases. In the 'System Parameters', the number of existing load cases may not have been determined correctly.

Version 23.0a - 21 April 2023
When using line joints, the check program or the system viewer could not be started. In the data editor, some table entries could not be saved. Holes were not taken into account in the polygonal mesh generator. Incorrect boundary descriptions could cause the mesh generator to abort. In the design situation for earthquakes according to the Eurocode base document, modified partial safety factors of the building materials were not taken into account.

Version 23.0 – 29 March 2023

In the torsional buckling check according to EN 1993 for I-beams, the web width was not correctly applied when calculating the rotation bedding from the profile deformation. In the crack width check according to EN 1992, the graphical representation of the steel stress was missing when the check was performed for the top side of the cross-section. In the bridge construction checks according to EN 1992, the action DS (support settlement) was not processed correctly when the 'complete combination' was selected.

Version 21.3.1 – 27 October 2022
During the dynamic analysis of structures with spring elements or line joints, a program abort could occur.

Version 21.3 - 25 October 2022
In the action dialog of the bridge design, a program abort could occur when processing load cases in groups. In the fatigue check of the concrete compressive struts of design objects, the torsional stress component was sometimes not determined correctly if the center of gravity of the cross-sections was selected as the reference system for the internal forces. Furthermore, the result data set could degenerate if this check was deactivated for individual check locations. In the case of a separate shear check for the x/y direction of area elements, the reinforcement selected for individual situations in addition to the maximum values may not have been saved correctly.

 Version 21.2a (License Manager) - 21 September 2022
When operating the license manager for network licenses, an unplanned termination of the associated service could occur.

Version 21.2 – 15 August 2022
In the deformation check according to EC5, the log and the maximum of several quasi-stable situations were not saved correctly under certain circumstances. In the shear joint check, the automatically determined height position was not correct in special cases.

Version 21.1c – 3 May 2022
During calculations according to Th. 3rd order, a singular stiffness matix could occur incorrectly under certain circumstances. When clicking a print list entry, the 3D section area was ignored in some cases. Clicking on a print list entry with a fire curve, a program abort could occur.

Version 21.1b – 11 April 2022
The table 'Total weight of concrete' was not displayed correctly. A speed problem occurred during the concrete design checks of a large number of elements. When copying geometric loads, one of the loads was not saved under certain circumstances. A program abort could occur when radially aligning supports.

Version 21.1a – 29 March 2022
Clicking on a print list entry with isoline display could cause a program crash.

Version 21.1 – 28 March 2022
In the bridge analysis based on DIN EN 1992-2, the coefficient gamma.p,fat was assumed to be 1.15 instead of 1.25 in the fatigue analysis for tendons with approval according to DIN 4227. The checks of design objects enclosing post-tensioned bars with subsequent bond and eccentrically defined cross-section, creep and shrinkage were treated as for bondless prestressing under certain circumstances.If the option "Design without consideration of given reinforcement ratios" was selected, the required reinforcement in the y-direction may not have been displayed correctly for area cross-sections with specified basic reinforcement.
In the punching shear check according to EN 1992-1-1 (basic document and NA Great Britain), the shear stress in equation (6.53) may have been set too high for circular edge and corner columns. In the action combinations according to SIA 262 and EN 1991-1-1 with NA, the combination of internal forces for cross-sections of design objects may not have been determined correctly if they were defined in an alternative design group.

Version 21.0b – 29 October 2021
For areas with arcs or circles, an unscheduled error message could occur in the mesh generator. The area was then not meshed.

Version 21.0a – 22 October 2021
If several polygonal mesh areas were entered, a program abortion could occur. Circular recesses within model surfaces could lead to a program abort during meshing. After importing IFC files with cross-sections without a valid material definition, the program could abort when the cross-section dialog was called. If individual reinforcement layers were fixed within the concrete tension zone, the output of the robustness and minimum crack reinforcement may not have been correct.

Version 21.0 – 7 October 2021
Annual update with a lot of interesting extensions.
Further information is available on the News page.

Version 20.1c – 15 March 2021
When renumbering cross-sections, unwanted entries could occur at the end of the model margins. When deleting load groups from the load group table, a program abortion may occur.

Version 20.1b - 3 March 2021
When moving objects to invisible layers, a program abortion may occur.

Version 20.1 - 2 February 2021
Using the "Mean in element" output option, the area reinforcement was possibly not displayed correctly. For design objects in connection with inactive tendon groups, the graphical output of the statically determined part P0 of prestressing was not correct. For insertion load cases within a load group, the defined load factor was not considered for 2D and 3D frames. For a group of line joints with defined spring stiffnesses, the spring stiffness at the transition from one line joint to the adjoining line joint was not determined correctly. During fatigue check for lateral reinforcement within the bridge recalculation on check level 2, the strut angle according to Equ. (12.23) was calculated with a concrete strength fcd determined by the coefficient alpha.cc = 1 instead of 0.85.

Version 20.0a - 2 September 2020
When opening the SIA settings, the 2013 output was always set. When printing a polygon from the print list, the label was positioned incorrectly.

The soil pressures for volume elements could not be displayed. In decompression check, regardless of the user specification the combination according to exposure class was always used (EN 1992-1-1, EN 1992-2 with NA Austria, Sweden, Great Britain). During recalculating of bridges, a ring-shaped specification of the effective tensile zone was only taken into account for crack checks on the basis of DIN EN 1992-2. When checking design objects, loss of tension due to creep and shrinkage was disregarded if the elements determining the losses were not made of concrete but of free material.

Version 19.1 – 28 November 2019
The pushover analysis for the non-linear detection of the earthquake safety for buildings has been implemented.
The crack direction in the calculation of nonlinear surface structures was possibly not determined correctly. In bridge recalculation on check level 1, the main compressive stress in box girders was always verified according to DIN-TR 102:2003 in state I irrespective of the user setting.
