Structural Foam Sheathing Test Program
The use of structural foam sheathing has been recently grown in residential building constructions in the United States. According to the manufacturers, the structural foam sheathing is a structurally strong panel with a high capacity to resist lateral loads. This study investigated the accuracy of the manufacturers’ published ultimate lateral load capacity for several types of structural foam sheathing in shear walls. Eight tests were conducted studying structural foam sheathing of shear walls subjected to monotonic testing following ASTM E564 test method. The structural foam sheathing products included 12.5 mm (½ in.) SI-Strong, 25.0 mm (1 in.) SI-Strong, 12.5 mm (½ in.) R-Max Thermasheath, and 2 mm (0.078 in.) ThermoPly Green. The wood stud wall frame was sheathed per the manufacturers’ specification with the structural foam sheathing in one side and standard 12.5 mm (1/2 in.) gypsum drywall in the opposite side of the stud wall. All of the stud wall specimens were 2.4 m×2.4 m (8 ft×8 ft) with 40.0 cm (16 in.) stud spacing, double terminal studs, double top plates, and a single baseplate. The walls were anchored with (3) 15.6 mm (5/8 in.) anchor bolts nominally spaced at 1.05 m (3.5 ft) and 75 mm×75 mm×6.2 mm (3 in.×3 in.×0.25 in.) plate washers. Likewise, Simpson HDQ8 tie-down anchors were attached to the end studs and anchored to the base with 15.6 mm (5/8 in.) anchor bolts. This study alternates the type, number, and spacing of sheathing and gypsum drywall fasteners. A minimum of two tests was performed with each type of sheathing detail per ASTM test method. Results from these tests show an 11 to 27 percent reduction in capacity when compared to the manufacturers’ published design values.
