“…Different types of Fibre-Reinforced Polymer (FRP) connectors have been proposed by several researchers for reinforced/prestressed concrete sandwich panels [9,[13][14][15], and some of them are even commercially available [16]. SFRSCC was also suggested as the material for sandwich panels, in which the connection between the concrete layers is assured by solid zones of concrete [17].…”

a b s t r a c tIn this paper, an innovative and thermally efficient sandwich panel is proposed for the structural walls of a pre-fabricated modular housing system. Traditionally, sandwich concrete panels consist of reinforced concrete wythes as outer layers, polystyrene foam as core material and steel connectors. However, steel connectors are known to cause thermal bridges on the building envelope, with possible consequent occurrence of condensation and mould problems. Furthermore, the reduction/optimization of the thickness of conventionally reinforced concrete layers is frequently limited by minimum concrete cover requirements for the protection of the reinforcement from corrosion. To overcome these issues, the proposed sandwich panel comprises Glass Fibre Reinforced Polymer (GFRP) connectors and two thin layers of Steel Fibre Reinforced Self-Compacting Concrete (SFRSCC). This paper presents the material and structural concept of the proposed building system. Moreover, the feasibility of using the proposed connectors and SFRSCC on the outer wythes is experimentally investigated through a series of pull-out tests where failure modes and load capacity of the connections are analysed.

“…This panel comprises Glass Fibre Reinforced Polymer (GFRP) connectors and two thin outer layers of Steel Fibre Reinforced Self-Compacting Concrete (SFRSCC). Although different types of FRP connectors have been already investigated for reinforced/prestressed concrete sandwich panels [2][3][4][5][6] and the SFRSCC was suggested as the material for sandwich panels [7], the combination of FRP and SFRSCC to obtain a sandwich panel that takes advantage of both materials is unknown at present phase.…”

a b s t r a c tIn the first part of this paper the authors describe an innovative sandwich panel that comprises Glass Fibre Reinforced Polymer (GFRP) connectors and two thin layers of Steel Fibre Reinforced Self-Compacting Concrete (SFRSCC). This second part of the paper reports the investigation performed by the authors based on the numerical simulation of these sandwich panels. The simulations use the Finite Element Method (FEM) software implemented by the second author (FEMIX). Through linear static analyses and consideration of Ultimate Limit State loading scenarios, parametric studies were performed in order to optimise the arrangement of the GFRP connectors and the thickness of the SFRSCC layers. Moreover, models considering a specific nonlinear behaviour of SFRSCC were also constructed in order to simulate the progressive damage of the panel induced by cracking. In the scope of the nonlinear analyses, emphasis is given to parameter estimation of fracture modelling parameters for the fibre reinforced concrete based on both inverse analysis and the fib Model Code.
