Abstract: From the perspective of building information modeling (BIM) technology, this article studies
and systematically classifies the structure features of Chinese classical architectures (CCA). Based on
the parametric modeling methods of BIM, informatization method of CCA is studied. This paper
proposes the CCA classification scheme and modeling procedure suitable for BIM. Then, taking
Zhengxinguagong of Dougong as an example, the modeling procedure is detailed demonstrated. The
presented parametric modeling method can be applied to the wooden building components and other
materials used in CCA, therefore it has an important significance in forming CCA building components
system and optimizing the part family libraries.

Key words: building information modeling, Chinese classical architecture, building component, parametric modeling
