Structural performance of GFRP connectors in composite sandwich façade elements
To take structural aspects into consideration in the SESBE research project, focusing on the development of “smart” façade elements a systematic testing and modelling program has been developed for the verification of the structural performance of the façade sandwich elements.
The present paper mainly focuses on the verification of the mechanical performance of the glass fibre reinforced polymer (GFRP) connectors of the novel type of façade element composed of reactive powder concrete (RPC) panels with foam concrete insulation between them. Because of the reduced thickness of the large façade elements, the performance of the connectors is critical for the entire structural concept.
The first series of the testing programme concerning connector performance are presented here. The results suggest that sufficient strength and ductility of the connectors can be ensured using GFRP in the proposed thin light-weight façade elements.
