Last year i designed 5 buildings using shipping containers along US and Canada.
It were small residential using couple containers, 2 story residential with basement ,heavy 3-4 story warehouses, apartments with parking . In results i got widely experience with this type of structures, knowledge about possibility for remodeling, strengthening.
(I attached some pictures from my previous designs using shipping container, FEA models).
