osb punching/bearing

[zennis]

How could I derive strengths for punching and bearing capacity for concentrated loads on OSB panels. I have developed a concentrated load based on bending capacity, but this load seems very small in comparison to the uniform load capacity. Any help would be appreciated.

2001 NDS Supplements, Panels section. This contains design procedure for panels in bending and shear. I don't think there's anything in there for bearing per se but it's a start.
