Based on the domain reduction method,this study employs an SEM-FEM hybrid workflow which integrates the advantages of the spectral element method(SEM)for flexible and highly efficient simulation of seismic wave propagation in a three-dimensional(3D)regional-scale geophysics model and the finite element method(FEM)for fine simulation of structural response including soil-structure interaction,and performs a physics-based simulation from initial fault rupture on an ancient wood *** verification of the hybrid workflow,a large-scale model of an ancient wood structure in the Beijing area,The Tower of Buddhist Incense,is established and its responses under the 1665 Tongxian earthquake and the 1730 Yiheyuan earthquake are *** results from the simulated ground motion and seismic response of the wood structure under the two earthquakes demonstrate that this hybrid workflow can be employed to efficiently provide insight into the relationships between geophysical parameters and the structural response,and is of great significance toward accurate input for seismic simulation of structures under specific site and fault conditions.

This paper discussed the selection criteria for Ordinary Urban Heritage (OUH) in Rattanakosin, the historic center of Bangkok through the case of ordinary restaurants and everyday foods. The OUH stands for an alternative approach to heritage understanding and conservation, derived from the notion of ordinary heritage, vernacular heritage, and urban heritage emphasizing the heritages of the everydayness of ordinary people. The OUHs have co-existed and inherited through the evolution of the city but are overlooked by the official conservation process. Ordinary restaurants and everyday foods were selected by 5 criteria, 1) appeared for more than 50 years;2) created, developed, and used by ordinary people;3) found as the clusters;4) able to be adapted to the urban context;5) exist until the present *** methodology applied to the analysis of the historical documents and Bangkok maps from 1887 to 1974, and the selection criteria developed from past research in another old commercial district of Bangkok were also reinvestigated with observational surveys. Ordinary restaurants and everyday foods are the outcomes representing the heritage of everyday life of ordinary people that are ubiquitously related to commercial activities.
