More than 90% of wooden frame houses are made up of components processed by pre-cutting. The drawings for pre-cutting are prepared by the designers of structural design offices and pre-cutting factories. In this study, interviews, drawing surveys, and questionnaires were conducted in order to understand the tendency of the joint arrangement of horizontal members of the framing designers. As a result of the survey, it was found that there were some cases where joints had to be placed at these locations, although they were designed not to be placed at push up part of the brace or inside the angle-tie.
