The purpose of this study is to discuss the statistical properties of the tensile strength of laminae with knots for glue laminated wood beams. In this paper, the diameter of knots, the longitudinal distance between two knots, and the tensile strength of knotted laminae are treated as random properties of knots. These properties are modeled stochastically based on the measured and experimental data. The stochastic model for knot randomness are employed to evaluate the percentile strength of knotted laminae by the Monte Carlo simulation and numerical calculations using probability distribution functions. According to the numerical results, the relationships between the basic knot diameter - lamina width ratio for the grading and the percentile value of tensile strengths are examined.
