DafStb Code of Practice

Members constructed of hollow-core slabs

Work on the DafStb Code of Practice on precast hollow-core slabs [1] began in November of 2017. The Code of Practice is planned to consist of two parts:

Part 1: Reinforced-concrete hollow-core slabs

Part 2: Prestressed hollow-core slabs

For the use of prestressed hollow-core concrete slabs, general national technical approvals [2] for design, implementation, testing and control were formerly issued in Germany. The approvals made special reference to the standards DIN EN 1992-1-1 [3, 4] and the harmonized product standard (hEN) DIN EN 1168 [5]. Following the judgment of the European Court of...
