On this page the novelties of previous InfoCAD versions are documented.
The following chapters provide you with the latest information and the most important changes with respect to the previous version 21 (PDFInfo).
General Information
 FEM structures can now be colored according to the following properties:
 Material
 Element thickness
 Bedding
 Base reinforcement as_{x} / as_{y}
 Creep factor, shrinkage factor
The corresponding quantities are documented in a legend.  Selected model surfaces are now displayed transparently.
 The hidden mode is now taken into account for model surfaces.
 In the data tree, the display of structural, model drawing and IFC objects can be controlled.
 All numerical output is now done with a TrueType Font.
 To improve visibility, the line widths on the screen are enlarged from 4K resolution.
 The size of the toolbars is now scalable.
 Line hinges have been extended by 3 degrees of freedom. Thus, hinge definitions can now be made for all 6 local directions.
 In the polygon dialog, reinforcing steel can now be placed automatically when entering circular ring crosssections.
 In the 'select group' dialog, it is now also possible to filter between single, line and area loads.
 Geometric single and line loads on beam elements can be converted into beam loads. This can be useful, for example, in connection with predeformation. The corresponding beam loads can also be converted back into geometric loads.
 Load case combinations can now be copied with the clipboard.
 In the display options, the element edges can now be hidden for filled area elements.
 Area element deformations can now be displayed in the local zdirection of the elements. This makes it easier to assess the radial deformations of cylindrical shells, for example.
 In the action dialog, the actions can now be resorted using by 'drag and drop'. This creates a better overview for many actions.
 When exporting tables to the clipboard (e.g. for further processing with Excel), all decimal places are now transferred as well.
Composite Section

Composite cross sections are now available for linear and nonlinear calculations of beam elements.
This enables the calculation of general composite structures with spatial loading. The internal constraints due to temperature loads as well as creep and shrinkage are also correctly captured.
The internal forces and the crosssection stresses are available.
FEM Analysis
 New development of extensive program libraries has accelerated the calculation speed significantly.
Nonlinear Analysis
 The 'Nonlinear Analysis' can now be started explicitly in the calculation menu and in the batch processing.
 Additional material laws were implemented for the nonlinear calculation of solid structures:
 Damage model (De Vree and Mazars)
 Elastoplastic damage model (Lubliner, Lee & Fenves)
 Plasticity model (DruckerPrager and Lubliner)  For the plasticity models Rankine, Raghava, Huber  von Mises, DruckerPrager and Lubliner, linear hardening can now be considered for solid models.
Dynamics

Bridge Checks according to EN 19922 and Recalculation Guideline
 Within the calculation settings, you can now select the complete combination as an alternative to the min/max combination. In this case, all possibilities of the interaction of actions resulting from the combination rule are taken into account for the determination of the verification internal forces. However, the number of internal forces increases exponentially with the number of inclusive load cases and can therefore require a lot of time for the checks.
 Within the serviceability checks of prestressed structures, two sets of internal forces with the variation factors rsup and rinf are now also examined for the min/max combination.

The method is suitable for largely regular structures whose basic eigenmode in the direction considered is not determined by torsional vibrations.
Dynamics
 The new ZPA (Zero Period Acceleration) method is a possibility of taking missing effective masses into account when using the response spectrum method.
For this, additional static load cases are calculated which consider the missing effective masses.  The button 'Reduce dead load' in the crosssection dialog is now also evaluated when calculating the dead weight.
SS EN 1992, 1993, 1995 with NA:201901 (EKS 11)
The checks have been adapted to the current edition of the National Annex Sweden. This essentially results in the following changes:
 When combining actions in the ultimate limit state according to SS EN 1990, Eq. (6.10a) and (6.10b), traffic loads are only taken into account within Eq. (6.10b), while Eq. (6.10a) is restricted to G and P. As a result, a more economical design can usually be expected.

OENORM B 19922, New Edition 2014
The bridge checks have been adapted to the new edition 201409 of the Austrian National Annex. This leads together with OENORM B 199211:201112 to the following changes:
 The reduction factor for the concrete strength α_{cc} = 1.0 is assumed for strength classes up to and including C50/60 according to Chapter 5.1.3.1. Above this class α_{cc} = 0.9 is still assumed.
 The torsion design for full sections uses the interaction equation (9AT) of B 199211.
 For the fatigue check of reinforcing steel the reduced stress ranges according to B 199211, Table 5AT, are applied.
 In the fatigue action combination the statically determined part of prestressing is reduced according to Chapter 8.3.2. The reduction factor can be defined in the section dialog.
 The modified action combinations according to Table 2AT are used for the decompression and crack width check. The action dialog has been adjusted accordingly.
