Lateral Resistance of Nailed Joints–A Test Method

The strength and stiffness of light-frame building components depend on the lateral resistance of the nailed joints between the connected members. Use of the Standard ASTM test to determine lateral resistance has resulted in controversy due to eccentric loading. Some researchers have proposed alternate test methods but, as yet, no agreement about the optimum test procedure has been reached. This study describes a new test apparatus which minimizes the effect of eccentric loading. Test data reveal that the gap between the connected members and the nailhead resistance both influence the joint loadslip characteristics. At low slip values, more scatter was observed in the test data, which indicates a change in slip criterion for joint load estimation in future research may be appropriate.
