Abstract:
The article discusses technologies that allow flat-plate floor systems to economically achieve spans in the 45 to 50 ft (13.7 to 15.2 m) range. These technologies include using ASTM A615/A615M Grade 80 steel, concrete mixtures with design strengths of 8000 psi (55 MPa) and higher, voided slab formers, and post-tensioned slabs with tendons banded over the columns in both directions.
