In 1987 the Commission on Prefabrication published the FIP Recommendations on the design of “Precast prestressed hollow core floors”. The document was highly appreciated by designers and public authorities because of the lack of guidelines elsewhere with respect to some specific features of the product, e.g. the absence of ordinary transverse reinforcement. It has also served as a reference guide for national standards and especially for the CEN product standard on Prestressed Hollow Core Slabs. During the production of the latter it was felt that some design rules were incomplete or missing. Furthermore, research carried out since 1987 has resulted in complementary knowledge on the behavior of hollow core floors, e.g. in combination with slender floor beams. The present Guide to good practice is intended to complement existing recommendations. The scientific research for the different items was carried out at Chalmers University of Technology, Sweden, for chapter 1; Politecnico di Torino, Italy for chapter 2; a Nordic research program carried out at VTT Finland for chapter 3; University of Nottingham, UK and Building Research Institute, Poland for chapter 4; 1st. di scienza e tecnica delle costruzioni dell’universita di Roma for chapter 5. The Commission wishes to thank the International Prestressed Hollowcore Association “IPHA” for its contribution, and particularly Tony Crane, for the work undertaken in the editing of this document.
