This article presents the Applied Technology Council (ATC) team’s observations following the 2017 Mw7.1 Puebla–Morelos, Mexico earthquake. The team was deployed in Mexico City to collect seismological, geotechnical, structural, and overall performance information. The focus was on non-ductile concrete structures, to support implementation of recently published FEMA P-2018 procedures and to identify study buildings for incorporation into NIST-funded ATC-134 ongoing project. This article presents seismological data with 71 strong-motion records processed and ready for use in engineering analysis, geotechnical observations, and characterization of sites visited. Analyses of the response of representative soil profiles are presented in the form of acceleration response spectra and seismic amplification at the ground surface. A comparison of the same analysis using records from the 1985 Michoacán Ms8.1 (approximately Mw8.0) earthquake is also discussed. The ATC team composed GIS maps with structural and geotechnical characteristics of the inspected sites, including color-coded damage of inspected buildings and estimated soil fundamental period to correlate observed behavior with potential soil–structure interaction resonance effects. Recommendations on further detailed studies based on this comprehensive set of case histories are proposed.

ATC Mw7.1 Puebla-Morelos 地震侦察观测：地震、岩土、地面运动、场地效应和 GIS 制图

本文介绍了应用技术委员会 (ATC) 团队在 2017 年 Mw7.1 墨西哥普埃布拉-莫雷洛斯地震后的观察结果。该团队被部署在墨西哥城，以收集地震、岩土、结构和整体性能信息。重点是非延性混凝土结构，以支持最近发布的 FEMA P-2018 程序的实施，并确定研究建筑物以纳入 NIST 资助的 ATC-134 正在进行的项目。本文提供了包含 71 个处理过的强震记录的地震数据，这些记录可用于工程分析、岩土观测和所访问地点的特征描述。代表性土壤剖面的响应分析以加速度响应谱和地表地震放大的形式呈现。还讨论了使用 1985 年米却肯 Ms8.1（大约 Mw8.0）地震记录的相同分析的比较。ATC 团队根据被检查地点的结构和岩土特征绘制了 GIS 地图，包括被检查建筑物的颜色编码损坏和估计的土壤基本周期，以将观察到的行为与潜在的土壤-结构相互作用共振效应相关联。提出了基于这组综合案例历史的进一步详细研究的建议。包括被检查建筑物的颜色编码损坏和估计的土壤基本周期，以将观察到的行为与潜在的土壤-结构相互作用共振效应相关联。提出了基于这组综合案例历史的进一步详细研究的建议。包括被检查建筑物的颜色编码损坏和估计的土壤基本周期，以将观察到的行为与潜在的土壤-结构相互作用共振效应相关联。提出了基于这组综合案例历史的进一步详细研究的建议。
