The seismic response of an instrumented 22-story rehabilitated building is presented. The building analyzed is as part of a complex (called CCUT) with three low-rise structures and a common basement founded on soft soil that was built in 1964. Since it was under construction until date, the building tower has experienced differential settlements and tilting. To mitigate such problems, the building has been subjected to several rehabilitations over the years. During the 1985 and 2017 high-intensity earthquakes in Mexico City, the tower suffered some damage. The aim of this article is to discuss the structural health monitoring system implemented for the tower and to describe the structure’s performance since the last rehabilitation in 2009. A monitoring methodology designed and implemented as a structural warning system based on five structural health indicators, two on seismic severity and three on structural performance, to automatically process seismic records, is presented. The results of the seismic response of the CCUT tower between 2011 and 2018 indicate that the structure had suffered moderate damage. Analysis of data, corroborated by building inspection, confirmed that the structure exhibited good performance during the 19 September 2017 Puebla-Morelos earthquake. The importance of the information obtained from the structural warning system is highlighted as a promissory tool for establishing a robust decision framework for occupants’ safety.

介绍了一座装有仪器的22层修复建筑的地震响应。被分析的建筑物是一个复杂的建筑（称为CCUT）的一部分，该建筑具有三个低层结构和一个建于1964年的软土地上的公共地下室。自建造至今，该建筑的塔身经历了不同的沉降和倾斜。为了减轻这种问题，这些年来，该建筑物已经进行了几处修复。在1985年和2017年墨西哥城的高强度地震中，这座塔遭受了一些破坏。本文旨在讨论为该塔实施的结构健康监测系统，并描述自2009年上次修复以来该结构的性能。提出了一种监测方法，该方法基于五个结构健康指标（两个针对地震严重程度，三个针对结构性能）设计并实现为结构预警系统，以自动处理地震记录。CCUT塔在2011年至2018年之间的地震反应结果表明，该结构遭受了中度损坏。经过建筑检查的数据分析证实，该结构在2017年9月19日的普埃布拉-莫雷洛斯地震中表现出良好的性能。从结构警告系统获得的信息的重要性被强调为建立可靠的乘员安全决策框架的工具。CCUT塔在2011年至2018年之间的地震反应结果表明，该结构遭受了中度损坏。经过建筑检查的数据分析证实，该结构在2017年9月19日的普埃布拉-莫雷洛斯地震中表现出良好的性能。从结构警告系统获得的信息的重要性被强调为建立可靠的乘员安全决策框架的工具。CCUT塔在2011年至2018年之间的地震反应结果表明，该结构遭受了中度损坏。经过建筑检查的数据分析证实，该结构在2017年9月19日的普埃布拉-莫雷洛斯地震中表现出良好的性能。从结构警告系统获得的信息的重要性被强调为建立可靠的乘员安全决策框架的工具。
