Post-Tensioned Slabs in Garages – A Rational Choice

The paper examines three different ceiling slab concepts for garages, considering common column spacings (8 × 8 m, 5 × 11.2 m, and 5 × 16.2 m). It provides a comparison between reinforced and post-tensioned concrete slabs, highlighting the advantages of post-tensioned ceilings in terms of maximizing parking spaces and reducing material consumption (concrete and steel). Optimizing space and minimizing material usage are crucial in modern construction to lower CO2 emissions and enhance spatial flexibility.
