ASTM F1575-17

Standard Test Method for Determining Bending Yield Moment of Nails

SIGNIFICANCE AND USE
5.1 Nails are a common mechanical fastener in wood structures. Engineering design procedures used to determine the capacities of laterally-loaded nailed connections currently use a yield theory to establish the nominal resistance for laterally-loaded nailed connections that are engineered. In order to develop the nominal resistance for laterally-loaded nailed connections, the bending yield moment must be known.
SCOPE
1.1 This test method covers procedures for determining the bending yield moment of nails when subjected to static loading. It is intended only for nails used in engineered connection applications, in which a required connection capacity is specified by the designer.  
1.2 The values stated in inch-pound units are to be regarded as standard. No other units of measurement are included in this standard.  
1.3 This standard does not purport to address all of the safety concerns, if any, associated with its use. It is the responsibility of the user of this standard to establish appropriate safety and health practices and determine the applicability of regulatory limitations prior to use.  
1.4 This international standard was developed in accordance with internationally recognized principles on standardization established in the Decision on Principles for the Development of International Standards, Guides and Recommendations issued by the World Trade Organization Technical Barriers to Trade (TBT) Committee.

This document is not an ASTM standard and is intended only to provide the user of an ASTM standard an indication of what changes have been made to the previous version. Because
it may not be technically possible to adequately depict all changes accurately, ASTM recommends that users consult prior editions as appropriate. In all cases only the current version
of the standard as published by ASTM is to be considered the official document.

3. Terminology
3.1 Definitions of Terms Specific to This Standard:
3.1.1 bending yield moment—the moment determined from the load-deformation curve that is intermediate between the
proportional limit load and maximum load for the nail. It is calculated by the intersection of the load-deformation curve with a
line represented by the initial tangent modulus offset 5 % of the fastener diameter.
3.1.2 deformed shank—a nail shank that has been mechanically deformed with annular rings, barbs, helical flutes, etc. for the
purpose of improved withdrawal capacity.
3.1.2.1 fully deformed shank—a nail shank that has deformation along the entire length.
3.1.2.2 partially deformed shank—a nail shank that that has both smooth and deformed sections along the length.
3.1.3 proportional limit load—is the load at which the load-deformation curve deviates from a straight line fitted to the initial
portion of the load-deformation curve. (See Fig. 1)
3.1.4 transition zone—the location of the transition from smooth shank to threadeddeformed shank on a partially deformed-
shank nail.
3.1.5 yield theory—the model for lateral load design values for dowel-type fasteners that specifically accounts for the different
ways these connections behave under load. The capacity of the connection under each yield mode is determined by the bearing
strength of the material under the fastener and the bending strength of the fastener, with the lowest capacity calculated for the
various yield modes being taken as the design load for the connection.
