“…In recent years there has been an increasing interest regarding the use of composite sandwich panels in the construction industry [1][2][3][4][5]. The high potential of those solutions for structural applications, as an alternative to more traditional materials, stems from their lightness, together with relatively high strength-and stiffness-to-weight ratios and improved durability [6][7][8].…”

“…In addition, a vast choice of materials and geometrical options allow for the integration of valuable non-structural functions that may be required for different applications. [1][2][3][4] One of these industries is construction and rehabilitation of civil infrastructure, for which sandwich construction presents considerable potential for structural applications.…”

This paper presents experimental and analytical investigations about the creep behaviour of sandwich panels comprising glass-fibre reinforced polymer faces and rigid polyurethane foam core for civil engineering applications. A full-scale sandwich panel was tested in bending for a period of 3600 h, in a simply supported configuration, subjected to a uniformly distributed load corresponding to 20% of the panel's flexural strength. Additionally, specimens of polyurethane foam core were tested in shear for a period of 1200 h, for three different load levels corresponding to 10%, 20% and 30% of the foam's shear strength. Experimental results were fitted using Findley's power law formulation. Creep coefficients, shear modulus reduction factors and time-dependent shear moduli were obtained for the polyurethane foam in shear. A composed creep model is proposed to simulate the sandwich panel's long-term creep deformations by considering the individual viscoelastic contributions from (1) the core material in shear and (2) the glass-fibre reinforced polymer faces in tension/compression. The composed creep model predictions adequately reproduced the full-scale panel's experimental results. In addition, a good agreement was found between the composed creep model predictions and the extrapolation of the power law fitting obtained from the full-scale panel test, for a 50-year period.

“…Recently, sandwich panels have been increasingly used in structural applications due to some main features such as its high strength and stiffness to weight ratio, its immunity to corrosion, and a low thermal and acoustic conductivity [15][16][17][18][19]. In the past, efficiency of using sandwich panels has been proved in several structural applications such as cladding [20], facades [21,22], roofing [23] and walls [24].…”

ElsevierAbdolpour, H.; Garzón-Roca, J.; Escusa, G.; Sena-Cruz, JM.; Barros, JA.; Valente, IB. (2016). Development of a composite prototype with GFRP profiles and sandwich panels used as a floor module of an emergency house. Composite Structures. 153:81-95. AbstractA series of experimental tests carried out on a composite prototype to be used as a floor module of an emergency house is presented in this paper. The prototype comprises a frame structure formed by GFRP pultruded profiles, and two sandwich panels constituted by GFRP skins and a polyurethane foam core that configures the floor slab.The present work is part of the project ''ClickHouse -Development of a prefabricated emergency house prototype made of composites materials" and investigates the feasibility of the assemblage process of the prototype and performance to support load conditions typical of residential houses. Furthermore, sandwich panels are also independently tested, analysing their flexural response, failure mechanisms and creep behaviour. Obtained results confirm the good performance of the prototype to be used as floor module of an emergency housing, with a good mechanical behaviour and the capacity of being transported to the disaster areas in the form of various low weight segments, and rapidly installed. Additionally, finite element simulations were carried out to assess the stress distributions in the prototype components and to evaluate the global behaviour and load transfer mechanism of the connections.
