Automated Model Construction of Urban Structures with Limited Digital Data

A key functionality of Integrated Earthquake Simulation which carries out regional earthquake simulations is automated model construction that builds a set of analysis models for different numerical analysis methods, using a variety of data which cover city and urban areas. In this study, we present the current state of the automated model construction for structures. Its unique feature is the ability to restore the configuration and estimate the structural properties for a target structure using a set of limited digital data. Engineering information such as design codes and regulations of the structure is systematically used to make up for the lack of the digital data. Explanation is made about the developed methodology and algorithms of the automated model construction for two kinds of structures: residential buildings and road bridges.
