Community Question:

Hello Bentley I'm working with Eurocode and I could see a slight difference between versions 15 and 2023, could you explain the reason?  I made a test using the next model which includes a SPAN line configuration

Answer:

Reviewing the model for this case our developers found that the root of the discrepancy in the results is within the definition of zero-length members at the end of the tapered sections - for example, in the below image we can see that the user has defined section PG1302 with a length of 0.001 m.

This definition was corrected how can you see in the next image where section PG1302 is defined at the end of the tapered section (again, with no zero length member definition)

When is corrected the input model file the results obtained from versions 15 and 2023 are equal (see below):

In this case, the discrepancy in the results is due to changes in our analysis engines and how they are parsing very small member segment Postlength (0.001) against the pre-set tolerance parameters in the Post module.

Actually, we are working on a solution to produce warning messages when zero-length members are being segmented and used for post-processing analysis such as span
