C-FIX Online

Includes current design standards, e.g. EN 1992-4 and EOTA TR 054 for the dimensioning of steel and bonded anchors in concrete as well as injection systems for anchoring in masonry. The anchor design in concrete can be performed either assuming a rigid base plate following a linear strain distribution or considering realistic stiffness conditions using a spring modeling approach.

Spring model in C-FIX Online

The linear spring model combined with a finite-element approach allows the determination of anchor forces of group fixings. This allows the comparison between anchor forces of linear force distribution and realistic anchor forces.

The calculation is conducted with the well-established finite element software RFEM® by Dlubal® in the background of our servers. The modelling and verifications are performed as usual in C-FIX Online.


To check and fulfill the requirements (assumption of a stiff base plate) the anchorage can be optimized by the following parameters:

  • Increasing the base plate thickness
  • Enlarging the connected profile
  • Applying additional stiffeners
  • Selecting another anchor system to optimize the force distribution
  • Changing the spacings.

Your time is valuable

The FEM calculation tool provides you with further information to design a sufficiently stiff base plate. It is no longer necessary to switch between the anchor design software C-FIX Online and a finite element software for the base plate calculation and design. This feature is a real time-saver!

Advantages FEM Design: ​

The realistic anchor forces are determined in the design software. ​
Easy optimizing of the anchorages.​
Multiple load cases can be defined and designed. ​
The profile and the stiffeners are considered for calculation. ​
The FEM Design can be used to check existing anchorages.​
The stiffness of the base plate can be verified. ​
The deformations are represented realistically.​
The add-on for the calculation of a sufficiently stiff base plate is based on the realistic anchor force calculation – quick and easy.​

Designs with the spring model are available in C-FIX Online only. A registration in myfischer portal is required. A license fee is charged for the spring model tool. 

The anchor design assuming a rigid base plate is possible without a license for free at any time. With the free version the anchor loads are calculated following a linear strain distribution (analog to Bernoulli hypothesis) and the requirements of the current design standards are fulfilled. An additional stiffness check might be required. The simplified steel stress verification is available without a license.
