  • the technique makes it possible to choose higher strength and stiffness, less volume of materials, greater flexibility, better economy or an arbitrary combination of these gains.
  • the technique makes it possible to create a total balance between bending forces, shear forces and stiffness (deformations) so that all design conditions can be fully optimized at the same time.
  • the technique presents a distinct minimized construction characterized by the ability that concrete can be placed exactly where it yields maximum capacity.
  • the technique offers material and cost savings compared with the conventional compact two-way reinforced slab structure.
  • the technique is suitable for both in situ works and for prefabrication.
  • United States Patent No. 9,879,423, which issued on January 30, 2018 to Breuning, relates to the existing problem of obtaining a self-carrying biaxial homogeneous lightweight concrete slab, and discloses a system and method comprising semi- prefabricated elements and special stringer structures, designed in such a way, that the finished flat slab structure appears homogeneous and can be achieved without temporary supports during the execution.
