Sources of Confusion in the Determination of ASTM Repetitive Member Factors for the Allowable Properties of Wood Products

Publication: Journal of Structural Engineering
Volume 138, Issue 1

Abstract

Confusion in the literature about the definition and calculation of repetitive member factors is identified. This confusion casts some doubt on the validity of the 1.15 repetitive member factor permitted in ASTM standards D245 and D1990.
