本文提出了一种多层次细节（LOD）仿真框架，以充分考虑城市建筑物震害仿真实际应用中结构类型、可用数据和仿真场景的多样性。首先，讨论了常用的建筑物地震模拟方法的主要特点，并建立了这些模拟方法的逻辑关系，以及可用的多源数据在不同的LOD。其次，提出了多LOD仿真框架的实现，并提出了一个统一的城市数据结构，使不同的LOD数据的有效管理和存储。最后，北京中央商务区，其中有各种类型的建筑物，详细说明了所提出的多层次细节框架。比较和讨论了不同LOD模拟的精度、效率和相应的要求。本文的研究成果可为复杂城市地区震害模拟的应用提供参考。
A multiple level-of-detail (LOD) simulation framework is proposed in this study, to take full consideration of the diversity of structural types, available data, and simulation scenarios in an actual application of seismic-damage simulation to urban buildings. Firstly, key features of the frequently used seismic simulation methods for buildings are discussed, and logical relationships of these simulation methods, as well as the available multi-source data, are established in different LODs. Secondly, implementation of the proposed multi-LOD simulation framework is presented, and a unified city data structure is proposed to enable effective management and storage of data with different LODs. Finally, the Beijing central business district, which has various types of buildings, is investigated in detail to demonstrate the proposed multi-LOD framework. The accuracy, efficiency, and corresponding requirements of different LOD simulations are compared and discussed. The outcomes of this work are expected to provide a useful reference for the application of seismic-damage simulations in complex urban areas.
