Hygric Properties

Hygric properties can be estimated directly from pore structure information, represented by a network of regularly shaped pores, extracted from a pore structure image to conserve the real topology. On this network, pore-scale models of moisture behaviour determine the hygric properties of moisture storage and transport. The reliability of this approach is validated with a sintered-glass filter. Despite its more limited heterogeneity and pore size range relative to typical porous building materials, it provides a good basis for validating crucial pore-scale moisture processes. Measured storage data compare well to the estimated ad- and desorption moisture retention curves as well as to the saturated and capillary moisture content. Furthermore, the simulated whole-range moisture permeability curve agrees acceptably with measured data. The variation in modelling the pore space as a pore network model is also analysed by considering two distinct pore network extraction methods. The measured and simulated moisture contents agree well for the whole capillary range. Moreover, the resulting transport properties are generally accurate for the whole moisture content range. On the other hand, the estimated vapour permeabilities show notable variations between the two pore network models.

Ming And Qing Dynasties

Some historical paintings are realistic enough to provide information for the study of ancient civil buildings and their corresponding living environment. This article uses architectural iconology, computer modeling, and quantitative analysis methods to interpret ancient images for contemporary research. This work selects Qingming Shanghe Tu , painted by Ying Qiu in the Ming Dynasty, and Gusu Fanhua Tu , created by Yang Xu in the Qing Dynasty to study the evolution of the living environment of ancient Suzhou at the natural meaning level. At the conventional meaning level, a comparison of the two images reveals that land use, landscaping, building performance, and building materials evolved due to social development. At the intrinsic meaning level, this development was found to be closely related to the expansion of urban construction, the development of compact landscaping, and the maturation of construction techniques. The architectural iconology method proposed by this work can be used to study other ancient buildings based on existing images.
