[pdf] The Meaning of Masonry W. L. Wilmshurst digsell https://lnkd.in/e3tcScHE The papers here collected have been written with a view to promoting the deeper understanding of the meaning of Masonry; to providing the explanation of it that one constantly hears called for. The meaning of Masonry, however, is a subject usually left entirely unexpounded and that accordingly remains largely unrealized by its members save such few as make it their private study. It seems taken for granted that reception into the Order will automatically be accompanied by an ability to appreciate forthwith and at its full value all that one there finds. The contrary is the case, for Masonry is … Read More » https://lnkd.in/ebmdD8cU

𝐋𝐨𝐦𝐛𝐚𝐫𝐝𝐢 Here proposed a graph derived from Theory of #Arch #Dams by G. #Lombardi: the #slenderness coefficient C takes into account the developed section of the dam across the valley F, the concrete volume V and the height of the dam H. What is the upper bound limit which sets the overall feasibility? 🎯 It is represented by the curve in the graph H x C = 3000

My talk given Tuesday 21 November 2023 for the IStructE History Study Group is available online. Understanding masonry bridges: a historical perspective. https://lnkd.in/ewpYBMnY Errata. I did not intend to suggest that Heyman was working on steel frames in the 1930s, but that he was involved, later, in work that had its start then. It was George Rennie’s brother John, not his father John, who was president of the ICE in 1946. Plenty more, no doubt. It turns out that there is a lot of history of arch mechanics to fit into an hour. I think I did that some sort of justice, but wish I’d given more time both in preparation and the talk to the issue of how far short that falls of providing an understanding of bridges, and what I think is needed to make progress. I was slightly shaken, when Andrew Smith asked me to do this some months ago, to realise that Bill’s early work is legitimately within scope of history of engineering. 1984 is 10% of the way to Hooke for a start! Bill’s computerisation of the line of thrust calculation was a lever to the work that Heyman had done to re-legitimise it. Both were needed to take it into mainstream assessment. There is also, obviously, a load of work after the 1980s. I didn’t even manage to mention Fraser Smith, who maintained and developed and supported ARCHIE and MULTI for years, let alone developments from elsewhere. But the originators of those are able to tell their own stories still. Comments and discussion most welcome.
