Abstract This study aims to examine the types, historical changes, and causes of longitudinal bay-spanning members among reinforcing members in the Dori(purlin)-direction, focusing on those used in the upper structural framework and Gongpo(bracket) complex of Korean traditional wooden architecture. This study examined 3,546 members from 228 buildings designated as National Treasures or Treasures. Based on their installation position and sectional width, these members were classified into two major categories and five subtypes. Their usage was then analyzed in relation to construction period, gongpo style, roof type, building usage, center bay span, and transverse length. As a result, this study revealed that dori-direction longitudinal members, which had originally served to bind structural frames, came to share vertical loads and gradually gained importance over time. This increasing importance resulted from the way these members responded to changes in architectural structure over time, as well as to the functional demands of building usage and structural requirements.
