This article deals with the proper numerical simulation of the response presented by an instrumented damaged-retrofitted building using a low computational cost linear-elastic model, using effective stiffness for its reinforced concrete structural members. The purpose is to identify the most appropriate criteria and considerations and to validate them against the actual behavior of the building registered during real earthquakes. Relevant structural aspects like concrete elastic modulus and soil–structure interaction effects are determined experimentally. Special attention is paid to select appropriate techniques to model the complex geometry of the North-South facades wall elements and their related coupling beams. Finally, time-history analyses of 20 March 2012 earthquake (service conditions demand) and 19 September 2017 earthquake (design conditions demand) are performed, both considering and ignoring the soil–structure interaction effects. Results point out that commonly adopted simplifications in numerical models of buildings must be correctly implemented to satisfactorily simulate their earthquake response.

监测墨西哥软土中的修复建筑以及对 2017 年 9 月地震的结构响应：第 2 部分：数值模拟

本文使用低计算成本的线弹性模型，利用钢筋混凝土结构构件的有效刚度，对仪表化受损改造建筑所呈现的响应进行适当的数值模拟。目的是确定最合适的标准和考虑因素，并根据实际地震中记录的建筑物的实际行为对其进行验证。相关的结构方面如混凝土弹性模量和土壤-结构相互作用效应是通过实验确定的。特别注意选择适当的技术来模拟南北立面墙元素及其相关耦合梁的复杂几何形状。最后，进行了 2012 年 3 月 20 日地震（服务条件需求）和 2017 年 9 月 19 日地震（设计条件需求）的时程分析，均考虑并忽略了土-结构相互作用效应。结果指出，必须正确实施建筑物数值模型中普遍采用的简化，才能令人满意地模拟其地震反应。
