Abstract

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.

基于有限数字数据的城市结构自动模型构建

集成地震模拟进行区域地震模拟的一个关键功能是自动构建模型，利用覆盖城市和城区的各种数据，为不同的数值分析方法建立一套分析模型。在本研究中，我们介绍了结构模型自动构建的现状。它的独特之处在于能够使用一组有限的数字数据来恢复目标结构的配置和估计结构属性。系统地利用结构设计规范、规范等工程信息，弥补了数字化数据的不足。介绍了住宅建筑和道路桥梁两种结构的自动建模方法和算法。

期刊介绍： Journal of Earthquake and Tsunami provides a common forum for scientists and engineers working in the areas of earthquakes and tsunamis to communicate and interact with one another and thereby enhance the opportunities for such cross-fertilization of ideas. The Journal publishes original papers pertaining to state-of-the-art research and development in Geological and Seismological Setting; Ground Motion, Site and Building Response; Tsunami Generation, Propagation, Damage and Mitigation, as well as Education and Risk Management following an earthquake or a tsunami. We welcome papers in the following categories: Geological and Seismological Aspects Tectonics: (Geology - earth processes) Fault processes and earthquake generation: seismology (earthquake processes) Earthquake wave propagation: geophysics Remote sensing Earthquake Engineering Geotechnical hazards and response Effects on buildings and structures Risk analysis and management Retrofitting and remediation Education and awareness Material Behaviour Soil Reinforced concrete Steel Tsunamis Tsunamigenic sources Tsunami propagation: Physical oceanography Run-up and damage: wave hydraulics.
