Many cities in the Philippines are situated near fault systems that can generate large magnitude of earthquakes. This paper describes the development of a city seismic response analysis approach for Metro Manila’s low- to mid-rise RC structures using frame models which are generated from GIS feature or BIM data. To create the three-dimensional (3D) models, features and structural details from BIM are used. Finite element method was used to discretize the models with mesh of line elements. Validations of generated models were conducted by comparing the results with those obtained using solid finite element model, commercial software and experimental test. The developed approach was applied to a scenario earthquake analysis wherein the causative fault is the West Valley Fault. Two cities within Metro Manila, that vary in distribution of low- and mid-rise building and site condition, were analyzed. The results of statistical analysis show that the variations in distribution of maximum interstory drift (ISD) between cities and between floor levels, are influenced by the height and floor plan area of the structures. Visualizations in both city-level and building-level reveal the areas that are critical for the considered scenario earthquake. Analysis of the computation costs shows that using frame models for response analysis of each city in Metro Manila leads to million-order degrees-of-freedom (DoF) to solve, and necessitates the implementation of data partitioning and high performance computing techniques.

使用从 GIS 特征和 BIM 数据生成的框架模型开发基于仿真的方法,以应用于马尼拉大都会中低层钢筋混凝土结构的城市地震响应分析

菲律宾的许多城市都位于可以产生大地震的断层系统附近。本文描述了使用从 GIS 特征或 BIM 数据生成的框架模型为马尼拉大都会的中低层钢筋混凝土结构开发城市地震响应分析方法。为了创建三维 (3D) 模型,使用来自 BIM 的特征和结构细节。采用有限元法对线元网格模型进行离散化。通过将结果与使用实体有限元模型、商业软件和实验测试获得的结果进行比较,对生成的模型进行了验证。所开发的方法应用于情景地震分析,其中成因断层是西谷断层。马尼拉大都会内的两个城市,分析了中低层建筑分布和场地条件的差异。统计分析结果表明,最大层间漂移(ISD)在城市之间和楼层之间的分布变化受结构高度和平面面积的影响。城市级和建筑级的可视化显示了对所考虑的地震情景至关重要的区域。计算成本分析表明,使用框架模型对马尼拉大都会的每个城市进行响应分析会导致百万阶自由度 (DoF) 的求解,并且需要实施数据分区和高性能计算技术。统计分析结果表明,最大层间漂移(ISD)在城市之间和楼层之间的分布变化受结构高度和平面面积的影响。城市级和建筑级的可视化显示了对所考虑的地震情景至关重要的区域。计算成本分析表明,使用框架模型对马尼拉大都会的每个城市进行响应分析会导致百万阶自由度 (DoF) 的求解,并且需要实施数据分区和高性能计算技术。统计分析结果表明,最大层间漂移(ISD)在城市之间和楼层之间的分布变化受结构高度和平面面积的影响。城市级和建筑级的可视化显示了对所考虑的地震情景至关重要的区域。计算成本分析表明,使用框架模型对马尼拉大都会的每个城市进行响应分析会导致百万阶自由度 (DoF) 的求解,并且需要实施数据分区和高性能计算技术。城市级和建筑级的可视化显示了对所考虑的地震情景至关重要的区域。计算成本分析表明,使用框架模型对马尼拉大都会的每个城市进行响应分析会导致百万阶自由度 (DoF) 的求解,并且需要实施数据分区和高性能计算技术。城市级和建筑级的可视化显示了对所考虑的地震情景至关重要的区域。计算成本分析表明,使用框架模型对马尼拉大都会的每个城市进行响应分析会导致百万阶自由度 (DoF) 的求解,并且需要实施数据分区和高性能计算技术。
