This study is concerned with a global assessment of the performance of steel building structures during the 1985 Mexico earthquake. The performance evaluation is carried out by a classification of buildings according to structural systems and height, a comprehensive damage survey, and a considerable amount of analytical modeling which permits an assessment of structural response with due consideration to the characteristics of the site soil conditions in Mexico City. Approximately 10 buildings are used for analytical evaluation. From the design information on these buildings, simplified analytical models are developed for nonlinear dynamic analysis. The results of the analyses are used to correlate predicted response with observed behavior. In this correlation, praticular emphasis is placed on an evaluation of the P- effect and cumulative damage effects. The goal of the project is to improve seismic design pratice for steel buildings.

本研究涉及对以下方面的业绩进行全球评估： 1985年墨西哥大地震中的钢结构建筑。 的 性能评估是通过对建筑物进行分类来进行的 根据结构体系和高度， 调查，以及大量的分析建模， 对结构反应的评估，并适当考虑 墨西哥城场地土壤条件的特点。 大约有10栋建筑物用于分析评估。 从 这些建筑的设计信息，简化的分析模型 的非线性动力分析。 的结果 分析用于将预测的响应与观察到的响应相关联， 行为 在这种相互关系中，特别强调的是 P效应和累积损伤效应的评价。 的目标 该项目旨在改进钢结构建筑的抗震设计实践。
