Innovative roof sandwich elements

Load-bearing behavior of sandwich elements with thin concrete shells and bar-shaped connectors

The presentation deals with an engineering model on the basis of tests regarding the load-bearing behavior of roof sandwich elements comprising 70 mm thin reinforced concrete shells each and a 200 mm thick core layer made of expanded polystyrene (EPS). Bar-shaped connectors made of glass-fiber reinforced polymer ensure the connection between the two shells made of normal-strength concrete and only constitute low thermal bridging. This structural design complies with the energetic requirements of EnEV (German Energy Savings Regulations) systematically and the amount of concrete required is...
