Abstract: Structural insulated panels (SIPs) (Fig. 1), as defined in ANSI/APA PRS 610.1, are part of a structurally strong and energy-efficient construction system that utilizes the strength of wood structural panels and the energy attributes of foam plastic insulation to provide cost-effective solutions for compliance with governing building codes. However, the popularity of SIPs has been hindered by the lack of systematic evaluations of their lateral load performance in wall applications. Because SIP walls are required to bear on the cap and sill plates (so-called “restrained”) so that vertical loads from the story above can be transferred to the story below or to the foundation, it is imperative that the lateral load performance of SIP walls reflects this configuration. Unfortunately, most SIP walls have been evaluated in a manner similar to conventional light-frame walls (the oriented strandboard facers are not allowed to bear on either cap plate or sill plate, so-called “unrestrained”) and therefore the actual lateral load performance of SIP walls may not have been realistically characterized.
