Abstract:
Recommendations for the design of prestressed concrete flat slabs being prodcuced by the FIP, although taking into account the Recommendations of ACI Committee 423, must also be in accord with the limit state design philosophies on which the new CEB/FIP Model Code will be based. Alternative methods of calculating the ultimate flexural and shear strengths are considered. Cable distribution and progressive collapse after accident damage are examined. The paper describes also the structure of the FIP Working Party, which would welcome technical contribution from designers with experience in this field.
