16Reinforced concrete voided slabs subjected to gravity and seismic actionsdissertations and by a wide range of manuals. See, among others, the works published in Great Britain (Wood, 1961), Germany (Leonhardt, 1972), Switzerland (Favre et al., 1994) and in the Scandinavian countries (Nielsen, 1984). A complete synthesis of mo- dern approaches to analysis and design of the slabs is provided by the text by Park and Gamble (2000).Figure 1.5. Voided slabs, alternatives for the arrangement of solid cast areas, areas around the columns and connections bands between the columns [Park and Gamble, 2000]Several national standards devote large sections to the design of these types of structu- res, which were transferred are at the basis of Eurocode 2 and of the ACI 318 standard. The latter regulation in particular dedicates a specific discussion on the seismic design of slabs on columns (so-called flat slabs).1.2. The constructive system of the voided slab floor in its historical deve- lopmentThe purpose of this introductory section is to demonstrate that the definition of modern design models of voided slabs is located, with the powerful capacity of this constructive system, at the point that is temporally closer to us of a line of theoretical and practical studies that goes far back in time.This short excursus is of fundamental importance to highlight the background against which the innovative system of U-boot Beton® voiding has emerged.up © Dalifoform Group © Daliform Grouup © Daliform Group © Daliform Group © Dalifoform Group © Daliform Group © Daliform Group © Daliform Grouup © Daliform Group © Daliform Group © Daliform Group © Daliform Group © Dalifoform Group © Daliform Group © Daliform Group © Daliform Group © Daliform Group © Daliform Grouup © Daliform Group © Daliform Group © Daliform Group © Daliform Group © Daliform Group © Daliform Group © Dalifoform Group © Daliform Group © Daliform Group © Daliform Group © Daliform Group © Daliform Group © Daliform Group © Daliform Grouup © Daliform Group © Daliform Group © Daliform Group © Daliform Group © Daliform Group © Daliform Group © Daliform Group © Dalifo form Group © Daliform Group © Daliform Group © Daliform Group © Daliform Group © Daliform Group © Daliform Group © Daliform Grou© Daliform Group © Daliform Group © Daliform Group © Daliform Group © Daliform Group © Daliform Group © Daliform Group © Dalifo iform Group © Daliform Group © Daliform Group © Daliform Group © Daliform Group © Daliform Group © Daliform Grouup © Daliform Group © Daliform Group © Daliform Group © Daliform Group © Daliform Group © Dalifo form Group © Daliform Group © Daliform Group © Daliform Group © Daliform Grouup © Daliform Group © Daliform Group © Daliform Group © Dalifoform Group © Daliform Group © Daliform Grouup © Daliform Group © Dalif form Grou
