Member stability check as per Canadian Steel code design CSA S16:2019

[TTTKAO]

Hello All,

I am designing a building with Canadian steel design code CSA S16:2019. This building's analysis is following Simplified stability analysis method as per clause 8.4.3 by use of RISA 3D. For all the members designed by the software, I am wondering if i still need do member stability check as per chapter 9, my feeling is i should do stability check as well. Let's take building vertical brace for example, i will get a design force from software as per external force, and as per chapter 9, there is load requirement and displacement requirement due to building column stability which is supported by vertical brace. so i should consider the sum of these two forces together to design the vertical brace? May I ask who is familiar with CSA S16 code can help to verify my understanding ?

Thank you!

They're not written all that clearly, but section 8 is mostly about stability of the overall structure and section 9 is mostly about stability of individual members and elements.

I'd heavily suggest reading the commentary in the handbook for both of those sections.
