The gist is a steel frame building using truss and columns and generally distributing weight from the roof to columns (load bearing)
I have see buildings that are only columns and joist with a different type of joist replacing the beams. The BA Tower is a supper thin building when it was built that took me by surprised when erection started on it. All the original steel for it that was to be built in the 80's made their way to the scrap yard.
