Abstract:

A test program to determine the resistance of plywood and OSB roof sheathing to uplift pressures created by wind flowing over a residential roof structure will provide valuable data to develop appropriate fastening schedules for roof sheathing. A new state-of-the-art piece of laboratory equipment is used to apply either static or dynamic fluctuating pressures to sheathing specimens. In conjunction with these experiments, pull-put tests of individual sheathing fasteners are performed and correlated to the results of the sheathing specimens. The results from this program will be used to justify existing fastening schedules. An overview of the test program is presented in this paper.
