ABSTRACT

In recent decades, seismic vulnerability studies in residential Historic Districts have increasingly resorted to simplified assessment methods, which, very often, are grounded on idealized models obtained from the analysis of the most recurring material and geometrical features in a specific area. This paper aims to discuss the procedure to get residential building models appropriate for simplified seismic vulnerability studies at Historic Downtown of Mexico City (HDMC). The models are built based on a comprehensive analysis from post-seismic reports, web-based inspections (i.e. 3D buildings in Google Earth and Street View 2017 panoramic), and existing literature in broad research domains – from history to urbanism, architecture, and conservation studies. From that analysis, it was obtained a set of building models organized into nine material classes (i.e. M1-M9), and four geometric categories (i.e. A, B, C, and D), whose matrix combination enables a final classification of 36 typologies. The neighbourhood of La Merced was selected as a pilot study area to obtain a typological matrix suitable to be applied to other areas of the HDMC.

摘要

近几十年来，住宅历史街区的地震脆弱性研究越来越多地采用简化的评估方法，这些方法通常基于对特定区域中最常见的材料和几何特征进行分析而获得的理想化模型。本文旨在讨论获得适用于墨西哥城历史中心 (HDMC) 简化地震脆弱性研究的住宅建筑模型的程序。这些模型是基于对地震后报告、基于网络的检查（即谷歌地球和街景 2017 全景中的 3D 建筑）以及广泛研究领域（从历史到城市化、建筑和保护）的现有文献的综合分析而构建的学习。从那个分析来看，它获得了一组建筑模型，分为九个材料类别（即M1-M9）和四个几何类别（即A、B、C和D），其矩阵组合可以最终分类为36种类型。附近的La Merced被选为试点研究区域，以获得适合应用于 HDMC 其他区域的类型矩阵。
