Structural visualization analysis applied to the preservation of architectural heritage: the case of stilted houses in southwest China

Abstract Architectural cultural heritage is critical to preserving global cultural and historical diversity. Despite China's abundance and distinctive architectural heritage resources, current approaches to analysis and preservation predominantly depend on traditional two-dimensional drawings and documents. These methods exhibit notable deficiencies in terms of accuracy, comprehensive restoration, and preservation. The vulnerability of these cultural heritages is further increased by inconvenient transportation and frequent natural disasters like earthquakes and landslides, placing more demands on preservation and restoration efforts, especially in Southwest China's hilly regions. In addition, the wide and dispersed distribution of buildings in this region adds another layer of complexity to the heritage protection process.This study focuses on the stilted houses, which are very typical of the Southwest. A comprehensive analysis was completed by classifying their structural types, performing geometric modeling, and combining real photos, exact dimensions, and material attributes. Five models were subjected to both dynamic and static analysis, as well as buckling, utilization rate, and ultimate state assessments. The data were displayed in a way that made it evident which structural forms had advantages and disadvantages, as well as which structural irrationality was present. Based on these findings, this study developed targeted architectural heritage protection techniques that were assessed using structural evaluations. These initiatives offer fresh approaches and insights into the preservation of architectural heritage.
