Racking strength of paperboard based sheathing materials

by Bi, Wu.

Abstract (Summary)
RACKING STRENGTH OF PAPERBOARD BASED SHEATHING MATERIALS by Wu Bi A small-scale racking test was developed to evaluate paperboard sheathing materials used for framed-wall construction and provided an economic alternative to standard wall tests. Both 16in and 32in sample sizes were investigated. The load-deformation response of three commercial sheathing boards was investigated, and initial racking stiffness and racking strength were proposed as parameters for characterizing the board. The racking test results showed that the initial paperboard racking stiffness correlated to elastic modulus and caliper, but the response was insensitive to paperboard orientation or test dimensions. Observations and results showed that both panel buckling and paperboard cutting at the staples affected the racking response. The results presented in this thesis indicated that the dominate factor influencing the racking response was load transfer to the frame through the staples as shown by the much stiffer response of samples where the sheathing was attached to the frame with glue.
