Anchorage in Concrete Construction

The year was 2007. I was handed a Nelson Stud catalogue. It was a wet noodle; time turned pages that told me nothing. Rows and numbers. Nothing.

Anchorage in Concrete ConstructionAnchorage-in-concrete was not a new topic, nor was there a refined understanding of the ‘how’ and ‘why’. You would thumb through the pages, find a number, flip back to the table at the start. Check the provisions of the case, find a number, apply it to the first number and on and on…

There are no longer thumbed-thru catalogues. Countless PDFs have rapidly replaced the table lined paper pages. There’s a different logo and perhaps a new name. Some words about vision followed by the impact language describing why there is one solution.

But anchorage-in-concrete is fundamentally flawed. It’s conditional. It’s situational. It tries to fit a form, but the form can’t truly be fitted once you attempt to understand the ‘how’ and ‘why’.

Werner and Rolf (primarily, but as well as a handful of others) casted studs into blocks of concrete. They observed the results and repeated the exercise under different conditions for the better part of three decades. This text is the accumulation of their findings that better explain anchorage-in-concrete—the ‘why’ and ‘how’. Dry as hell, but worth the slog.
