Buckling for Cross Section Optimization through Karamba

unhandled

(Ming890110) #1

Hi Karamba Team,

I’ve created a truss model and feed it into Karamba for section optimization.

The issue I have faced is when the model is exported to GSA for analysis, the steel utilization value in certain compression members are over 1.

Looking further into the analysis model, it seems that the local buckling was over utilized which prompted me the question, does the component in Karamba take into account local buckling checks when it comes to optimizing sections.

I’ve attached the GH file below for your perusal.

Looking forward to your reply.

Thanks!
Best
