Method of test for evaluation of truss plates used in lumber joints
|Publication Date:||1 January 2014|
This Standard provides basic procedures based on joint ultimate load or a limiting slip for the determination of the lateral strength resistance and lateral slip resistance of truss plate teeth embedded in sawn and structural composite lumber members.
This Standard provides for the determination of the lateral strength resistance and lateral slip resistance of nails embedded in lumber members when used in nail-on truss plates. When this Standard is so applied, the word "tooth" is understood to be replaced by the word "nail".
This Standard provides basic procedures based on truss plate ultimate strength for the determination of the tensile and shear strengths of the net section of the plates.
The capacities determined by testing methods and procedures described herein, and corrected for the variations in the ultimate tensile strength of the plate material used in the manufacture of the test truss plates, will yield values that may be adjusted for use in engineering design, such as specified in CSA O86.
In this Standard, "shall" is used to express a requirement, i.e., a provision that the user is obliged to satisfy in order to comply with the standard; "should" is used to express a recommendation or that which is advised but not required; and "may" is used to express an option or that which is permissible within the limits of the standard.
Notes accompanying clauses do not include requirements or alternative requirements; the purpose of a note accompanying a clause is to separate from the text explanatory or informative material.
Notes to tables and figures are considered part of the table or figure and may be written as requirements.
Annexes are designated normative (mandatory) or informative (non-mandatory) to define their application.
