Abstract: As the architectural form of the highest grade and most complex construction found in the Lanzhou region， the gable-and-hip roof features gable framing and craftsmanship that represent the most prominent characteristics of local construction techniques. Its gable framework， in particular， reflects a distinctive status that sets it apart from other architectural forms. Focusing on the gable construction of gable-and-hip roof in the Lanzhou area， this study employs architectural surveying and interviews with master carpenters to systematically analyze both the typology of “typical practices” in the structural framework and the construction logic of “typical components”.The research aims to uncover the principles underlying the gable construction of gable-and-hip roof， with the goal of supplementing and refining the inheritance of wooden construction techniques in the Lanzhou region， and further contributing to the establishment of a construction atlas of gable-and-hip roof across different areas.
