Steel Tube Institute has a free tool to verify that your specified HSS wall thickness is adequate. It's called HSS Connex, link below.

And yes, there is a free webinar on September 18th, comparing the use of HSS to...
Per the below article from the Steel Tube Institute, "when you use an A53 pipe, you will pay in part for the sealant that producers use to coat the outside of the pipe. In order to weld to these pipes, a fabricator must remove the sealant you have paid for, an unnecessary cost and extra step in...
Steel Tube Institute has loads of resources on HSS connection design, including articles with design examples, design manuals with more design examples, HSS Connex to determine minimum wall thickness at connections, spreadsheet design tools for professional members, etc. You can start with this...
The Steel Tube Institute has a great new article, as well as a reference guide for concrete filled columns, which includes some software recommendations. They also have a spreadsheet design tool for filled and unfilled columns, available to professional members. Here are the links to each of...
Here are a few resources for designing shear plate connections to HSS Columns. I don't think they address your question regarding global design of the column, but they may, and they certainly address how to handle the design of the connection...
This article offers some cost-effective alternates to through plate moment connections: https://steeltubeinstitute.org/resources/expert-tips-for-cost-effective-hss-specification-and-fabrication/
Upsizing the wall thickness is a good option. Steel Tube Institute has a tool called HSS Connex for determining minimum wall thickness required to meet connection requirements. https://steeltubeinstitute.org/hollow-structural-sections/hss-connex-tool/
Awesome, thank you very much, @Retrograde. I went to the link you sent, and they also had a video summarizing their composite column design capabilities, and it looks promising. I'll check out the free trial.
@lexeng18 I deleted the prior thread (once) because your response is odd and unnecessarily negative. The second paragraph, "not to be harsh" serves no purpose. However, because you insist on posting it again, I will leave it for now.
I am putting together a reference guide for design of concrete filled HSS and have many articles and design manual references, however I would like to include software recommendations if software exists that is capable of concrete filled/composite HSS design. LPile was recommended for this...
Thank you Azcats. I'll check it out. I'm compiling software resources to provide to structural engineers, as part of a quick reference guide for concrete filled or composite HSS.
I'm specifically looking for software solutions. Yes, there are some tables in the AISC manual, and more extensive tables in the STI Design Manual, which we've already included in the reference guide.
Check out these two articles for advice on sizing cap plates:

This article doesn't necessarily answer your question but it provides practical considerations for concrete filled HSS columns and may point you in the right direction.

I am working on putting together a list of references on concrete filled, or composite HSS column design, including connections to composite HSS members. The list will include articles, design manuals, etc. I would like to include possible software solutions as well, if they exist. There is...
Here is an FAQ from the Steel Tube Institute on mitered connections that might help:
https://steeltubeinstitute.org/faq/welding-of-mitered-l-or-knee-connections/
@bridgedisciple My understanding is that a primary reason for hesitancy in using HSS in bridges is because AWSD1.5 (the welding spec for bridges) does not include HSS. However, for pedestrian bridges, you are not required to use AWSD1.5. You can use AWS D1.1, which does include HSS, and which...
The Steel Tube Institute has an article containing a fully worked HSS to HSS connections example with axial, shear and moment loads. You can find it at the link, and then scroll down about halfway, to the section that says: HSS-to-HSS Connection With Shear, Axial and In-Plane Moment Example...
