Structural Section Database

[dik]

Does anyone know if the Canadian CISC section Database for W sections is the same as the AISC. For section properties for HSS, does the AISC use A500 properties or does it have values for both specs?

Curious mimes want to know...

Uh, Packer up in Canada was the main proponent of HSS back in the day.

I don't know offhand if the databases are the same exactly, but one would hope.

Surely you know about this little wrinkle from back when.

Thanks... good links...

I just updated my W section database based on the AISC properties. Version 16 is the latest... the one I was using was version 14... My latest project has sections that the AISC has, but the CISC doesn't. About a decade back I was in contact with Packer... One of the HSS producers he had referenced in an article had a couple of errors... AISC section database is free... the CISC charges $25 for theirs...

I design steel connections and occasionally get a little flack for one of my comments. If the EOR includes ASTM A500 as a possible alternative. I stipulate that all the HSS properties have been reduced to meet the reduced section properties of A500. They don't like it because I penalise all HSS. I seem to recall the AISC included provisions for A500, but don't know if they have separate tables.

CISC V12.1 has tables for HSS ASTM A500 which indicates the Tdesign property.

When I last did a comparison (AISC V15 to CISC V9.2), the CISC and AISC tables only differed slightly for W shapes. AISC had 6 extra shapes (W40, W36, W24, W21, W18 groups and mostly the heavy weight sizes). CISC had a few W24 and W18 sections that were called out differently. I believe that the AISC tables originate with imperial values and they provide a converted metric value for all properties, so there is slight difference if you run a size side-by-side but it should be in a regular margin-of-error for design.

AISC and CISC also provide different properties (not different values) for angles.

The AISC Tables for HSS are for ASTM A500 (reduced wall thickness).
If you want one for ASTM A1085 (nominal wall thickness), it can be found here:

Thanks skeletron... I've incorporated the AISC sections as CISC ones... I cannot imagine there being a problem... the project had a bunch of W18s that weren't available in the CISC database I had...

Thanks dauwerda... I thought something like that was up... but wasn't certain.
