ICC ESR's
ICC ESR's
(OP)
I apparently live a sheltered life...
I've never heard of ESR's until recently. I've never sought an ESR unless referred to within this site.
Throughout Eng-Tips, i'm seeing many of you referring to ICC ESR's so frequently that it appears as though some of you know these reports as well as IBC and ASCE.
Is there a report for every structural product on the market?
How do i find a list of products that have an ESR?
What (basic) occasion would i refer to an ESR?
Any other helpful advice?
Thank you!

Basic difference is 'product' vs. 'engineering material'. I don't need an ESR for structural steel or concrete or CMU because the materials are governed by ASTMs and then I calculate strength and other properties based on whatever the applicable code is. I don't need any information from whoever produces the physical material beyond their conformance with applicable ASTMs. Used to be able to do this for items like metal deck as well, though a lot of those guys have started using proprietary connections (particularly sidelaps) that then kick me back to needing design values from someone else.
RE: ICC ESR's
When I am not familiar with a manufacture and they have an ESR, I feel more comfortable than relying on the manufactures claims. If I am comparing the capacity of expansion anchors or sheet metal screws with ESRs, I know they were tested using the same criteria.
If you want a better idea of what products have ESRs, you might browse through ICC's list organized by CSI divisions at http://www.icc-es.org/reports/index.cfm. Or look through ICC's list of Acceptance Criteria (AC) at http://www.icc-es.org/Criteria/criteria/index.cfm?.... But just because there is an AC or an ESR for a product doesn't mean it is widely recognized. There are ESRs for headed studs, and deformed bar anchors, but I don't often see them referenced.
