Dear SACS User,
I aware there is a feature to perform X-Brace or K-Brace at SACS.
however if I model it manually, do I need to define that the brace is X-Brace or K-Brace even though I have manually made the braces looks like X-Brace however I define the member as standard?
How the concept of X-Brace or K-Brace works?
thanks
I am not an expert of SACS but as far as I know, you still have to define it as X-Brace or K-Brace. It affect to K-Factor and Buckling length for calculation. Maybe, you can read it in SACS manual section 2.6.1.9.4 if you still confuse. Hopefully, it answer your question.

Hi Nur,
Thanks to look at my query. If it is K-Factor and buckling length I can applied it manually as I applied for the rest of member.
I aware at SACS IV section 2.6.1.9.4 mentioned about this, however I cannot see in the statement the benefit to apply it using the feature of X-Brace and K-Brace.
What is the different if I define the X-Brace as standard member then I apply K-Factor and buckling length manually, compare with using the X-Brace feature and define it brace type as X-Brace?
Hi Rizky,
As mention on section 2.6.1.9.4, the feature is applied if certain condition appear in the load case (e.g. the cord member is on compression and another member is on tension in the K-brace case).
My understanding for your case can make your model more conservative due to the longer buckling length even outside of above condition.
If you use X-Braces and K-Braces physical elements will automatically be created. You may find them:
Hope that helps
