ABSTRACT
The Sandwich-Plate-System can be a new way to build light decks of steel railway bridges. To use it as transverse spanning deck it needs to span up to 5 m. Therefore the system has to be thicker than the ones tested in former projects. Different forms and cross-sections with thick faceplates have to be assessed to achieve good designs of SPS decks for the use in railway bridges. It is also necessary to gain knowledge about the bearing behaviour of thick SPS in general and the time-dependence of the core material polyurethane. The paper on hand will present the ongoing research project, which investigates these topics.
