Effect of Length on the Tension Strength between Mechanically High-grade and Low-grade Chinese Fir Lumber
Introduction The design of structures using I-joist, wood trusses, and so on may be governed by the strength of the structural dimension lumber in tension parallel to the grain, in the past, the tensile strength properties of dimension lumber were derived by testing small, clear specimens with adjustments for defects such as knots and the slope of the grain. A more recent approach to the development of tensile strength properties was in-grade testing of full-size lumber. The length effect on tensile strength using the brittle fracture theory is described as a relation between the length and strength of two members with the same cross-sectional shape and different lengths.
