Abstract: Taking the wooden frame of the Shang-Character Gate from an ancestral hall in Shexian County as a case study， this paper begins by categorizing its components and tracing their historical evolution. It then analyzes the characteristics of decorative components integrated with both structure and space from the perspectives of decoration-structure integration and decoration-space integration. Moreover， through mechanical analysis and eye-tracking experiments， this research adoptes a combined qualitative and quantitative approach to verify the regularity characteristics in the integration of structure， decoration， and space within the Shang-Character Gate style wooden frame across different component combinations. These findings demonstrate that the design and placement of the decorative components fully reflect both mechanical principles and aesthetic considerations. From a viewer's perspective， the spatial interest points in the perception of the wooden carvings show marked centripetal and hierarchical tendencies.
