Answer:
Hello,
Unbraced length is defined as follow image.
In your model file, the element no.41&44 is assigned as a member. Therefore, those separated elements are designed as one member using the Member Assignment function. Among them element no.44 is unfavorable for the load combination, program design a member for the element no.44., so the Ly is printed as 3.6m. Please refer to the below result table.
Thank you.
