For floor and roof sheathing applications of oriented strand board (OSB), its resistance to concentrated static load (CSL) is a critical property in assessing its strength performance. The objective of this study was to determine whether CSL properties were related to other panel properties. A small scale lab CSL test was also developed in order to facilitate CSL test using conventional laboratory equipment. In addition, the effects of panel variables on CSL performance were investigated. Eight types of commercial 4&feet; x 8&feet; x 7/16&inches; OSB panels were examined. Shear strength was evaluated using a customized five-point bending test. Models for CSL performance based on stepwise multi-linear regression were developed that predicted CSL performance reasonably well. According to the model, shear strength in the perpendicular direction was more strongly correlated to the CSL performance than the other panel properties. A small scale lab CSL test was found to give consistent results with the standard CSL test.
