Circular Concrete Columns

[EngDM]

Hey all,

I found this web-app a while ago

https://people.wallawalla.edu/~louie.yaw/MyWebApps/RoundConcColumns/roundinteraction.html

However, after comparing American vs Canadian codes it doesn't appear that this tool would be applicable. Concrete factors and the whitney stress block constant stress assumed in the American is handled differently in the Canadian code.

Do any of you know of something similar out there for use under the Canadian code?

This is ACI 318 based but shows the physics at play quite well. I'm unfamiliar with the Canadian code differences but since this is a full example calc maybe you can find the differences and set up your own Canadian version in excel. I use this method in excel and iterate over the neutral axis location to generate my own Interaction diagrams for circular bridge columns and drilled shafts regularly.

Whitney stress block is not very good for anything other than rectangular sections!
