Abstract | This paper presents the structural behaviour of an emerging prefabricated wall system made up of glass fibre reinforced rigid polyurethane foam (PUF) and Magnesium Oxide (MgO) board. Full-scale wall specimens were prepared and tested under transverse bending, compression and shear. The results of the experimental investigation showed that the behaviour of the composite walls is governed by the strength of the MgO board. A complete interaction between the rigid PUF and MgO board was achieved using epoxy adhesives. In compression, a 17% lower failure load was measured for wall specimen with the MgO board attached to the wall frame with a 10 mm offset from the bottom plate than the wall with the sheathing flushed to the bottom plate. Under in-plane shear test, the single and two-panel composite wall systems exhibited similar shear stiffness and strength. The provision of tie-down anchor bolts increased the shear strength by almost 15% but has no significant contribution to the shear stiffness. |
