报告摘要：
In studying the structural performance of traditional timber structures, joints are the most critical and complex elements. The joint of column and penetrating beam has been widely used in traditional timber buildings and it plays a crucial role in resisting horizontal loads such as seismic and wind forces. Research into the shape and dimensions of these joints forms the foundation of understanding their structural performance. Current scholarship primarily focuses on remaining historic timber structures in Japan, documenting the shape and dimensions of these joints through repair reports and on-site investigations. 
China and Japan have a long history of exchanging architectural techniques. The penetrating beam technique is generally believed to have been introduced from China during the Song Dynasty. However, most research to date has concentrated on Japanese cases. Therefore, further research into the structural performance of penetrating beam joints in traditional Chinese timber structures is necessary. 
The authors have built a strong foundation in studying the shape, dimensions, and structural performance of Japanese column and penetrating beam joints [1]. This paper aims to expand the focus to include China, using Yingzao Fashi, the earliest surviving ancient Chinese manual on timber construction techniques, issued in 1103, which details various methods of constructing timber buildings from the Song Dynasty, through descriptions and illustrations. This study, based on a literature investigation, summarizes the shapes and joint techniques for horizontal structural members resembling penetrating beams in the Yingzao Fashi. Additionally, by reviewing previous Japanese studies, this paper compares the similarities and differences in column and penetrating beam joints between China and Japan.
