In the last decades, the need for improved thermal-structural integrated solutions for building construction has prompt towards the development of Structural Insulated Panels (SIPs), a cost-effective wall system capable of transferring shear loads among panel layers and minimizing localized heat loss This study explored both mechanical and thermal behaviour of SIPs, composed by an Expanded Polystyrene (EPS) core within two oriented strand board (OSB) sheets. Six panels (1200x1200x170mm3) were tested under in-plane horizontal load in two configurations: (i) three single SIP wall; (ii) three double SIPs wall, joined together with a block spline and metal connections. Both specimens were anchored to a lower steel metal beam through anchor bolts and hold-downs. Moreover, the panels were characterized as regard the steady-state thermal behaviour. The study demonstrated that this wall system is a viable solution for sustainable buildings since it presents high shear strength, elevated ductility and good thermal-hygrometric performance.

Abstract

In the last decades, the need for improved thermal-structural integrated solutions for building construction has prompt towards the development of Structural Insulated Panels (SIPs), a cost-effective wall system capable of transferring shear loads among panel layers and minimizing localized heat loss This study explored both mechanical and thermal behaviour of SIPs, composed by an Expanded Polystyrene (EPS) core within two oriented strand board (OSB) sheets. Six panels (1200x1200x170mm3) were tested under in-plane horizontal load in two configurations: (i) three single SIP wall; (ii) three double SIPs wall, joined together with a block spline and metal connections. Both specimens were anchored to a lower steel metal beam through anchor bolts and hold-downs. Moreover, the panels were characterized as regard the steady-state thermal behaviour. The study demonstrated that this wall system is a viable solution for sustainable buildings since it presents high shear strength, elevated ductility and good thermal-hygrometric performance.
