Over 2000 buildings were surveyed by members of the Colegio de Ingenieros (CICM) and Sociedad Mexicana de Ingenieria Estructural (SMIE) in Mexico City following the Puebla-Morelos Earthquake of 2017. This inventory of surveyed buildings included nearly 40 collapses and over 600 buildings deemed to have structural damage. Correlation of damage with peak ground acceleration (PGA), peak ground velocity (PGV), predominant spectral period, building location, and building properties including height, estimated stiffness, and presence of walls or retrofits was investigated for the surveyed buildings. The evidence available suggests that (1) ground motion intensity (PGV) drove the occurrence of damage and (2) buildings with more infill and stiff retrofit systems did better than other buildings.

墨西哥城钢筋混凝土建筑地震反应的观测

2017 年普埃布拉-莫雷洛斯地震后，墨西哥工程师学院 (CICM) 和墨西哥工程师协会 (SMIE) 的成员对 2000 多座建筑物进行了调查。 调查的建筑物清单包括近 40 座倒塌和 600 多座建筑物有结构损坏。针对所调查的建筑物，研究了损坏与峰值地面加速度 (PGA)、峰值地速 (PGV)、主要频谱周期、建筑物位置和建筑物特性（包括高度、估计刚度以及墙壁或改造的存在）的相关性。现有证据表明，(1) 地震动强度 (PGV) 推动了损坏的发生，以及 (2) 具有更多填充和刚性改造系统的建筑物比其他建筑物做得更好。
