The September 19, 2017 earthquake (M_w = 7.1) was the most damaging earthquake that stroke Mexico City since the September 19, 1985 earthquake. However, taking aside the southeast region of Mexico City, where very strong ground motions were recorded, in the central region for the city, spectral accelerations were more than well-covered by the design spectra of Mexico City building codes since 1987. In this paper, and based upon a detailed inventory of 2458 damaged structures, the observed structural damage is discussed from several angles, in particular, the relationships of observed damage with: a) use for the structure, b) structural systems, c) number of stories, d) plan geometries and conditions of structural irregularity, e) conditions which increases the seismic vulnerability, and f) seismic codes, spectral accelerations and global ductility demands assessed from recorded ground motions. Although it can be concluded that total number of structural collapses and severe damage was smaller for buildings designed according to the collapse-prevention design philosophy in Mexico City (802) in comparison to former older codes (967), this total number is not acceptable from an engineering, social and economical viewpoints. In the opinion of the authors, engineers should start thinking seriously on moving towards resilient-based seismic design strategies to reduce such large extent of damage in modern, newly constructed buildings in very active seismic zones such as Mexico City.

2017年9月19日地震（M _w = 7.1）是自1985年9月19日地震以来席卷墨西哥城的最具破坏力的地震。但是，除了记录有非常强烈的地面运动的墨西哥城的东南地区之外，在该城市的中部地区，自1987年以来，墨西哥城建筑法规的设计频谱就远远超过了频谱加速度。本文，并根据2458处受损结构的详细清单，从多个角度讨论了观察到的结构损坏，尤其是观察到的损坏与以下各项之间的关系：a）用于结构，b）结构系统，c）楼层数， d）规划几何形状和结构不规则性条件，e）增加地震脆弱性的条件，以及f）地震规范，根据记录的地面运动评估频谱加速度和总体延性要求。尽管可以得出的结论是，与以前的旧规范（967）相比，根据墨西哥城（802）的防塌设计理念设计的建筑物的结构倒塌和严重破坏的总数较小，但是从总数上来说，这是不可接受的具有工程，社会和经济观点。作者认为，工程师应开始认真思考如何采用基于弹性的抗震设计策略，以减少在诸如墨西哥城这样活跃的地震带中的现代新建建筑中的此类破坏。尽管可以得出的结论是，与以前的旧规范（967）相比，根据墨西哥城（802）的防塌设计理念设计的建筑物的结构倒塌和严重破坏的总数较小，但是从总数上来说，这是不可接受的具有工程，社会和经济观点。作者认为，工程师应开始认真思考如何采用基于弹性的抗震设计策略，以减少在诸如墨西哥城这样活跃的地震带中的现代新建建筑中的此类破坏。尽管可以得出的结论是，与以前的旧规范（967）相比，根据墨西哥城（802）的防塌设计理念设计的建筑物的结构倒塌和严重破坏的总数较小，但是从具有工程，社会和经济观点。作者认为，工程师应开始认真思考如何采用基于弹性的抗震设计策略，以减少在诸如墨西哥城这样活跃的地震带中的现代新建建筑中的此类破坏。
