Only ULS Design Situations for EN 1990 Base + Timber

API & Interfaces

Hello everyone,

I am currently working with Python in RFEM 6 and the Dlubal API 2nd Generation in version 2.12.7.

I have noticed a reproducible problem when I set the following settings in the BaseData standards, as I want to use the Timber Design Add-on:

base_data.standards.combination_wizard_standard_group = (RFEM.BaseData.Standards.COMBINATION_WIZARD_EN_1990_BASE___TIMBER_STANDARD_GROUP)
base_data.standards.combination_wizard_standard = (RFEM.BaseData.Standards.COMBINATION_WIZARD_NATIONAL_ANNEX_AND_EDITION_EN_1990_BASE_TIMBER_DIN_2012_08_STANDARD)

Although the standards are set correctly, my Design Situations change to 4x ULS and no SLS situation.
The automatic generation of design situations or load combinations should, in my opinion, create both ULS and SLS situations according to EN 1990 / timber.
However, as soon as these two lines are active, only ULS combinations are generated.
The total number of generated load combinations remains the same, but instead of the expected SLS design situations, the ULS situations are simply created four times, as the Design Situations are also changed to four times ULS.

If I deactivate these two lines, the design situations are generated correctly again, i.e., with the expected SLS situations.

I have also checked the official release notes of the Dlubal API but found no documented fix for this behavior.

Has anyone else observed the same or can Dlubal confirm whether this is a bug in API 2.12.7 or the associated RFEM version?

Thank you very much!

Hi Fabian147,

I cannot reproduce the issue, but I am working with the latest version of the API 2.14.1. Do you have a chance to update? Maybe the issue is in your script? If you provide me more details I might be able to help.
E. g. fi you change the NA in the RFEM UI the design situations will be reseted to uls for example. If you do the same in the code, it will have the same behavior/result.
