Need some advice, please. Trying to design some tall brick columns that support a lot more bricks above a lintel. Need to understand how much weight a single brick (at the bottom of the column) can take before failing. I'm not planning to build a single brick column, but understanding how much a single brick can take will help with my calculations. My bricks are rated at around 10 N(ewtons)/mm2. The bricks are 215 x 102.5 mm, total surface area of 22,037 mm2. So I think that means the most a single brick can support 220,375 N, evenly distributed. That equates to around 22,464 Kg or around 22 Tonnes. This seems far too much, as a maximum load before fracture. Where have I made a mistake?
