Allowable roof snow load rafter spans are based on design loads. Add to Alert PDF. This abstract is a brief summary of the referenced standard.

Shear Testing by means of torsion is the most common method determining strength Four point bending methods are also specified. The applicable standards are ASTM for clear wood fullsize specimens.

Separate tables are employed to present the data on woods grown in the United States and on adtm grown in Canada. Method A provides for the use of the results of surveys of wood density involving extensive sampling of forest trees, in combination with the data obtained from standard strength tests.

Some building codes permit reductions of certain design loads for large tributary areas and steeppitched roofs. This standard is also available to be included in Standards Subscriptions. These reductions may vary from code to and are not considered in computations for spans presented WWPA publications.

Guidelines for the interpretation of the data in terms of assigned values, information basic to the translation of the clear wood values into working stresses, presently available data with appropriate provisions for their application and use, and methods for estimating some useful mechanical properties by relating them to other properties are presented herein as well.
