Release notes

Overview of the published InfoCAD program versions

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 colour legends were sometimes displayed with dimmed colours. The conversion of IFC objects has been improved. The (new) numerical result averaging in the element was corrected.

Version 20.0 - 12 August 2020
Annual update witha lot interesting extensions.
Further information is available on the News page.

Version 19.2c – 5 June 2020
The labels for linear support reactions could not be selected.

Version 19.2b – 20 May 2020
The 'Update' function in the construction stages led to an endless loop.

Version 19.2a – 19 May 2020
The dialog for entering a line load could not be started. The context function 'Divide model face' was reactivated.

Version 19.2 – 15 May 2020

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.

Version 19.0a – 9 October 2019
The dialog for the analysis settings 'Dynamics' has been corrected.

Version 19.0.1 – 30 August 2019
Updates have been made in the listing of the concrete checks. The load type temperature by using the arc length method could be handled not correctly.

Version 19.0 - 15 August 2019
In the setup of 13.8.2019 the uninstaller may be not registered correctly.

Version 19.0 - 13 August 2019
Annual update with focus on user interface, nonlinear calculations and concrete checks.
After copying cross sections between construction stages their material properties were incorrect under certain circumstances. For design objects, a rotation of the cross section was not correctly considered if the center of gravity was selected as the reference point. During checking the reinforcing steel stresses in the SLS for area elements, results of non-relevant reinforcement layers were graphically displayed under certain circumstances.
In the shear check according to DIN 4227, the length of the verification section was not determined correctly under certain circumstances. A new imported Revit® analysis model was not saved under certain circumstances..
