Distribution models and specified values of Young's Moduli of the structural timbers used for conventional construction were analyzed and reliability levels were obtained at serviceability limit states. And based on the current Working Stress Design, reliability levels were also obtained at ultimate and serviceability limit states. The results are summarized as folows: (l)Same safety levels as steel structures and 2×4 wood frame structures were gotten at serviceability limit states. (2)The current allowable unit stress in Building Law Enforcement Orders seem to be a little small from the point of view of the reliability level comparing to those of steel structures and 2×4 wood frame structures. (3)The values of Young's Moduli recommended by The Architectural Institute of Japan also seem to be a little small from the point of view of the reliability level. (4)Size effect couldn't be seen in the structural timbers used for conventional construction.
