Anstar has developed dimensioning software for designing the load-bearing frames of buildings. The software applications are used to specify the resistance and utilisation rates of the frame connections with Anstar products.

  • The software has been designed for easy use and illustrative presentation.
  • The dimensioning of the structure is illustrated using colour graphics, showing the resistance of the structure and connection pieces as well as the utilisation rates and whether they are exceeded.
  • The software dimensions the connection according to the latest European standards.
  • The software performs the calculation for the erection stage, final stage and accident situations.
  • The software produces strength calculation materials for building control.
  • The user interface and printing language options are Finnish and English.
  • The downloadable programs work on Windows 10 and 11 systems.
  • Our technical support team is happy to assist you with the detailed use of the programs.

For structural design, Anstar has made Revit blocks, ACAD blocks and Tekla Structures components for its products, enabling the flexible use of Anstar products in the design work.

We have invested in software development to make the design process as seamless as possible for you. The latest downloadable software versions and the web-based ACOLUMN® program can be found in our software portal. Create an account in our system to start your design work!

ACOLUMN®- to design column shoe/anchor bolt connections for concrete elements.

The ACOLUMN® software is used to design column shoe/anchor bolt connections for concrete elements. The software is used for designing the following types of element connections:

  • Element column coupler and foundation connections rectangular and round columns
  • Shear wall coupler and foundation connections
  • Moment stiff beam-to-column connections



We are committed to developing our software to make design work as effortless as possible. Create an account and start using the program!

  •  Bolt connections between steel column and concrete
  • Anchor plates
  • ADE® and ADK® bracing connections for concrete columns


  • Software is used for preliminary design of A-BEAM S®– and W®-type composite beams in hollow-core slab floors for design-and-build deal reference plans.
  • The software calculates the preliminary dimensions for composite beams based on the loads.
  • The software uses the A-BEAM W®– and S®-type beam selection.
  • Anstar is responsible for the final dimensioning of the beams.

Tekla’s 3D components for Anstar products

Components for Anstar products have been prepared in the Tekla Structures 3D modelling software and can be used for modelling the products.

NEW! AOK® column shoe tools have been renewed for Tekla Structures software. As an extension of the Tekla Structures software, there are two tools for modeling column connections – the placement tool “AnstarAOKLocator” and the bracket design tool “AnstarAOK”. First, save the components to your machine and then follow the user manual.

First save the components on your computer and then follow the installation instructions. The components can be used starting from software version 17.0.4. If you need components for older software versions, please contact Anstar’s technical support.
