Version 01/17

Version 02/16


Glulam according to EN 14080:2013 implemented for Germany and Italy.
The "old" Glulam timbers are marked with * (for example GL24c*).

Version 01/16


British Standard for Eurocodes implemented for steel, timber, concrete and aluminium.

Version 02/15


If timber and steel were defined but steel was not used in the system, this led to an error in the max/min-superposition.
In concrete design with shear and tension the angle of the inclined strut was always set to 45 degrees.
The calculation with alternative groups in the max/min-superposition was optimized.

Version 01/15


Stainless steel according to EN 1993-1-4 is implemented for DIN EN 1993:2010 und ÖNORM EN 1993:2007.


For specified superpositions you could get error no. 9 during timber design in EN 1995.
EN 1993: If there were no bar failure in the specified superposition for calculation of 2nd order theory. + bar failure, then the output was for calculation of 1st order theory.

Version 02/14


- For high values of shear forces in EN 1993 there could appear problems in the output.

Version 01/14

- Eurocode is now the default code.
- In rare cases for EN3 GammaM = 0.0 was written in the output. Hower the calculation was correct.
- DIN EN 1995 was calculated with the actions of the pure Eurocode.
- For EN5 and new positions the design in the maxvalues of specified superpositions were due to DIN 1052. After saving the position and reload the design was for the correct code.
- Design of a single loadcase was not possible fo EN9.
- Design of haunches corrected for DIN 18800.

Version 02/13B

The following problems due to application of EN3 have been fixed:

- In Version 02/13A the calculation with EN3 could lead to wrong stresses. The internal forces were not affected. This problem already has been fixed with a patch.
- In the max/min-superposition for +/- loadcases only the plus-part hase been used.
- If the system was build with steel and aluminium (EN3 and EN9), only the first applied material was used.
- The application of the maximum of specified superpositions could lead to an abnormal termination when the specified superpositions were defined in the serviceability limit states.

Version 02/13A

- EN3 with more possibilities during calculation due to equation (6.2)

Version 02/13

- Problems corrected fo steel design in structures with several materials.
- In the Three-Dimensional Frame the shear stress due to QI has been too high for rectangle and square bar.
- Under certain conditions failured bars could have an utilization factor.
- If there were no bar failure in the specified superposition for calculation of 2nd order theory. + bar failure, then the output was for calculation of 1st order theory.
- If there were no bar failure for calculation of specified superposition with 2nd order theory. + bar failure, then it could be possible that for the maxima of specified superpositions not all specified superpositions were considered.

- Depending on the existing actions the program could crashed while clicking on the load input dialogue
