The goal of this study was to review the visual grading and allowable stress determination methodologies for thedomestic softwood. Previous studies used different grading (KFRI 1995-27, KFRI 2000-39, KFRI 2007-3, KFRI2009-1) and allowable stress determination methodologies (ASTM D 245, KS F 2152, JAS 1990). The results of thevisual grading were different by each researcher. Compared to the 1st grade proportion from the previous studies usingthe previous specification on visual grading (KFRI 1995-2007), a higher 1st grade proportion was found from the studiesusing the current specification (KFRI 2009). Compared to the allowable stress values from the small clear sample,the higher allowable stress values from the structural size were found. The results indicated that the strength reductionfactor used in small clear sample was too conservative for the different grades. To obtain consistent results for thegrade, it is required to have experts in visual grading and authorized organizations. An official standard methodologyfor the allowable stress value determination needs to be defined for the reliable stress value.
