InfoCAD 17.0 (August 2017)

The following chapters provide you with the latest information and the most important changes with respect to the previous version 16 from July 2016 (PDF-Info).


General Information

  • A new 'overlapping test' was introduced to control the model drawing. This allows you to find overlapping drawing objects.
  • Texts can now be defined right-aligned or centered.
  • The UNICODE standard is now accepted in the program interface to use alternative character sets. Now it is possible to use e.g. Cyrillic, Greek, etc. characters.
  • The selection features of the command 'Select group...' was significantly extended.
  • In the print preview, a new arrow object is available as a supplement to the commentary box.
  • The commentary box can now be filled with a hatching pattern or a background image.
  • The torsional moment of inertia Ix of polygonal cross sections can now be given a factor. So the torsional stiffness of several cross-sections can be simultaneously reduced.
  • The preparation of the geometric stiffness matrix for the calculation of buckling eigenvalues is now parallelized also.
  • The soil settlement calculation with the modulus of compressibility method has been parallelized.
  • The FEM line hinges now support spring stiffnesses. These are suitable for modeling balcony connections (e.g. according to the Schöck Isokorb® FEM Directive).
  • The speed of the 'Dynamic train load' can now be increased incrementally with the function 'Generate load cases'.

Construction Stages

The functionality has been completely revised and extended. The following improvements were made:
  • In the calculation menu you can now start the calculation of all available construction stages. If defined, the batch call of each construction stage is started with the selected checks.
  • In the new docking window all construction stages are listed and can be loaded directly. The set view remains.
  • Properties (e.g. tendon geometries) can be copied to all selected construction stages.
  • Objects can be subsequently added and copied to other construction stages.
  • The 'CS attribute' has been removed. The connection of the files is now only made via file names.

Dynamics

  • The overlay of the laminate stresses was supplemented for the evidence using the response spectra method.
  • In the log, the load sums of the individual modal contributions are now listed.
  • The position of the mass center point is calculated (added in the listing).
  • The preparation of the mass matrix was parallelized.

Structure Analysis for Fire Scenarios

  • For the steel layers taken from the concrete checks, it is now also possible to differentiate between cold-formed and hot-rolled.

Recalculation Guideline for Road Bridges

  • For documentation of the load bearing capacity, the table representation and the detailed log were enhanced.
  • The check of the concrete and steel stresses, the crack width and the fatigue can now be performed alternatively on the basis of the existing or required reinforcement. The selection is made in the analysis settings.
  • In the section dialog, the selection of checks has been revised and expanded, in order to be able to select previously bundled checks separately.
  • For the robustness, crack and torsional reinforcement of beams and design objects, the utilization is now also proven.
  • The utilization check of bending, robustness, crack and shear reinforcement has been added for area elements.
  • In the standard design for lateral force and torsion, the existing basic reinforcement is maintained as in the bending check. In addition, the required reinforcement without basic reinforcement is checked.
  • The check against fatigue for concrete struts is now performed separately for the stress directions y and z.
  • In the fatigue check for shear reinforcement in level 2, the concrete strut angle is now determined according to Eq. (12.23) of the guideline.
  • Alternatively, the fatigue check for lateral force in level 2 can now be performed on the basis of the main tensile stress criterion.
  • All checks were adapted to the BAST interpretations from February 2017.

IFC - BIM

  • The conversion of IFC objects has been fundamentally revised.

Reinforced Concrete Checks acc. to EN 1992-1-1 and EN 1992-2

  • The check against fatigue for concrete struts according to EN 1992-2, Chapter 6.8.7, has been supplemented.
  • In the section dialog, the selection of checks has been revised and expanded, in order to be able to select previously bundled checks separately.

Steel Checks acc. to EN 1993-1-1

  • For double symmetrical I and H profiles as well as for rectangular box sections, the plastic cross-section resistance is optionally determined according to Chapters 6.2.3 to 6.2.10.
  • The cross section library was extended by hot-rolled hollow sections according to EN 10210-2.
  • For pipe and rectangular sections, the stability proof for bending and pressure according to EN 1993-1-1, Chapter 6.3.3, has been supplemented (lateral torsional buckling program).

Timber Checks acc. to EN 1995-1-1

  • In case of biaxial lateral force load, the condition of equation (6.13) is now also verified for the resulting shear stress. The interaction equation (NA.55) of the National Annex Germany is only evaluated in case of double bending.
  • In the analysis settings, it can now be selected which cross-sectional dimensions are decisive for the determination of the coefficient kh according to Chapter 3.2 and 3.3.

Nonlinear System Analysis

  • It is now also possible to calculate prestressed structures. The tendons are implemented directly into the stiffness matrix and act in the concrete composite.
  • The calculated tendon stresses and utilization are determined for the graphical representation.
  • The crack strains can be shown for area elements. This allows a good assessment of the expected crack pattern.
  • The start reinforcement is now added to the listing.
  • For 3D beams, the complete stress state is now listed and can be visualized.
  • The extreme steel stresses for beam elements can now be visualized.

License Manager

  • The environment variable INFOSERVER can be used to specify a number of computers for license connections. If the primary computer fails, InfoCAD automatically connects to a backup computer if a license manager is active there.
  • In order to improve the reliability, we now also offer licensing special backup hardlocks.

Webserver

  • The web server has been migrated to SSL to ensure maximum connection security. Data transmission is now basically encrypted.
