After the 2017 Puebla-Morelos earthquake, the Applied Technology Council (ATC) funded a mission to Mexico City to collect structural, geotechnical, seismological, and damage information on concrete structures. The collected data set includes 70 reinforced concrete buildings and contains photos, design drawings, ground motion records, ambient vibration data, and reconnaissance observations, where available. This article presents the most important structural observations and instrumentation findings. The data show that, in buildings with a flexible lateral system, the unreinforced masonry infill walls resisted substantial load and prevented more severe damage to the structural system. Many previously retrofitted buildings failed in locally unreinforced areas, because retrofits did not comprehensively strengthen all weaknesses in the building. Significant damage was also observed in buildings with weak story irregularities and buildings founded on weak soil.

ATC Mw7.1 Puebla-Morelos 地震侦察观测：结构观测和仪器

2017 年普埃布拉-莫雷洛斯地震后，应用技术委员会 (ATC) 资助了一项前往墨西哥城的任务，以收集有关混凝土结构的结构、岩土、地震和损坏信息。收集的数据集包括 70 座钢筋混凝土建筑物，并包含照片、设计图、地面运动记录、环境振动数据和侦察观测（如果有）。本文介绍了最重要的结构观察和仪器发现。数据显示，在具有柔性侧向系统的建筑物中，未加筋的砌体填充墙可抵抗大量载荷并防止对结构系统造成更严重的损坏。许多以前改造过的建筑在局部未加固​​的地方都失败了，因为改造并没有全面加强建筑的所有弱点。
