Elastomeric Adhesive Properties-Shear Strength, Shear Modulus, Creep, and Recovery
Keywords:<i>Pseudotsuga menziesii</i>, construction adhesives, mobile homes, wood buildings, residential construction
AbstractThree commercially available adhesives, approved for use in field glued floor systems, were evaluated for potential structural application in light frame wood buildings. All had adequate static shear strength for common floor and roof sheathing uses. Two were sufficiently rigid to generate useful composite action. One displayed relative creep compatible with wood structural design practice but two had excessive relative creep. The adhesive with good creep properties also had good recovery properties. The other two had poor recovery properties. One adhesive that had good shear strength in a conventional block shear test would not consistently sustain stress as low as 25 psi for more than four days. All tests were conducted on bonded wood specimens at 70 F (21 C) and 12% EMC.
