the Greeks had discovered that heating iron would help to harden it, but it was still brittle and not very useful for any tasks requiring strength. However, iron is a relatively soft and brittle metal on its own. Iron has been known to man for several thousands of years the earliest iron implements found thus far are from Egypt and were made about 3000 b.c. Within a few decades, foundries were making railroad track, bridge girders, locomotives, armor plating, and other steel-based products. By revolutionizing the steel industry, the Bessemer process helped to spur on the Industrial Revolution. This, in turn, provided steel at relatively low cost to various industries. The Bessemer process made possible the manufacture of large amounts of high-quality steel for the first time. In 1856, Henry Bessemer (1813-1898) developed a new method for manufacturing steel. The main area of interest was actually the deflection, as the larger of the 2 beams is 5.5 meters (18 feet) long.English Inventor Henry Bessemer Develops Process to Produce Inexpensive Steel Overview My Stress studies showed that the maximum Von Mises stress was well within the yield for the material used. This area of the project was the highest risk, and because of this, I ran some of my own calculations in Inventor using the FEA environment.
From the image below, you can see the opening in the walls, and pretty much the full extent of the steels. We knocked out a corner of the bottom floor, and needed to support our upstairs neighbours. Luckily I was able to catch this, and we were able to rectify the situation BEFORE any work was carried out.īelow is a picture of the major structural work. supporting structural beams on non load bearing stud wall). The scary part of all of this is that human error happens, and on 2 of the 3 areas that needed the structural engineers attention, mistakes were made (i.e. I employed a structural engineer to do all of the calculations and specify the steel beams that are ultimately going to support the structure. A lot of the project has involved structural work and some pretty heavy steel work. We are about half way through having an extension added to our home.
