InfoCAD 17.2 (May 2018)

General Information

  • When changing edges (length or endpoint), the adjacent model faces will be adjusted to preserve them.
  • The snap mode 'end' has been extended to elements. Now it can be 'caught' on element ends that are not at the node due to an eccentricity.
  • In the dialog 'Renumber cross sections' the cross section colors can be displayed.

Prestressing

  • A new tendon group view has been added.This represents the selected tendon group over its parameters.

Systemviewer

  • For Windows 10, the export of AVI files has been added. For playback, a corresponding player is required, e.g. Microsoft Media Player®.
  • Solid models can now be exported in 3D Manufacturing Format (3MF) and Standard Tessallation Language Format (STL). Both formats are suitable for output on 3D printers and are supported by the Windows 10 apps "3D Viewer" and "3D Builder".

InfoCAD BIM RV Add-In for Revit®

  • From Revit imported calculation models can now be updated after changes. Adjustments made in InfoCAD stay preserved.

EN 1992-1-1, EN 1992-2 and National Annexes

The crack width checks has been completely revised and extended. The following improvements were made:

  • For circular cross-sections the effective tensile area Ac,eff can be determined ring-shaped now. This can be used e.g. for considering the specifics of bored piles and spun concrete columns.
  • For profiled sections the coefficient kc is calculated according to user specification either as per Eq. (7.2) or as per Eq. (7.3), optionally different for the top and bottom of the cross-section.
  • As an alternative to the direct crack width calculation the simplified check through limitation of the bar spacing can be choosed.
  • A constant average steel strain within Ac,eff can optionally be chosen as the basis for calculation.
The documentation has been adapted to the new version of the DAfStb "WU-Richtlinie" (directive for waterproof concrete structures) as of December 2017.

OENORM B 1992-1-1:2018-01

The concrete checks have been adapted to the new version of the National Annex Austria of Jan 2018. The following improvements were made:

  • In Eq. (6.52) the upper limit for the punching resistance with punching shear reinforcement is set to kmax · vRd, c with kmax = 1.65.
  • The maximum punching resistance vRd, max according to Eq. (6.53) is now limited to the recommended value of the base document.
The documentation of the crack width checks has been adapted to the new version of the OEBV directive "Wasser­un­durch­lässige Betonbauwerke - Weisse Wannen" (waterproof concrete structures – white tanks) as of February 2018.

Recalculation Guideline for Road Bridges

The crack width checks has been revised and extended. The following improvements were made:
  • For circular cross-sections the effective tensile area Ac,eff can be determined ring-shaped now.
  • The coefficient kc now can be calculated optionally different for the top and bottom of the cross-section.
  • As an alternative to the direct crack width calculation the simplified check through limitation of the bar spacing can be choosed.
  • A constant average steel strain within Ac,eff can optionally be chosen as the basis for calculation.
The reserves in the torsion reinforcement can be taken into account for the lateral force check. The use of this option is relevant in the following checks:
  • For the lateral force checks in level 2, the existing shear force reinforcement for calculating the compression strut angle in Eq.(12.12) and Eq. (12.15) will be increased by the existing torsion reinforcement.
  • For the fatigue check in level 2, the existing shear force reinforcement for calculating the compression strut angle in Eq.(12.23) will be also increased by the existing torsion reinforcement.
  • By determining the utilization of the existing shear force reinforcement, the unused reserves of the existing torsion reinforcement is added to the shear force reinforcement.
  • In the fatigue checks for the existing shear force reinforcement, the unused reserves of the existing torsion reinforcement is also used for lateral force removal.
