 note = {application/pdf, The size effects in shearing strength were investigated by means of the torsional test in two species of Western hemlock and Red lauan. The torsional tests were carried out by using four kinds of specimens whose size were two times, four times and eight times as long as the smallest specimens respectively. The shearing strength of these specimens was measured. The results obtained are summarized as follows : 1) It was observed that there was a high negative correlation between logarithms of the shearing strentgh <special>(log γmax)</special> and logarithms of the volume of the specimens <special>(log V)</special>. Preticularly, the regression line in three kinds of specimens, except the smallest one (Type I specimen), was very nearly identical. Accordingly, it was considered that the shearing fracture coincided with the weakest link theory. 2)The constants of the size effect of Western hemlock specimens were 10.8 (shearing strength in radial section) and 10.7 (shearing strength in tangential section). The constants of Red lauan specimens were 10.0 (shearing strength in radial section) and 9.26 (shearing strength in tagential section).},
