Workshop on Repair and Retrofit of Existing Structures Tech-niques and Design Procedures (Building Case Studies Mexico City)

美国现有的结构是在采用现代抗震设计规范之前设计的，在地震期间存在动力性能差的潜在问题。地震后结构的升级和修复方法对防震减灾和地震工程具有重要意义。该研究项目传递了墨西哥在1985年9月墨西哥地震后开发的与结构修复和翻新有关的知识和技术。研究方法主要采用案例研究的方法。案例文件侧重于设计过程和使用的技术方法。然后，这些结果可以直接转移到美国的地震减灾工作中。

Existing structures in the U.S. which were designed prior to the adoption of modern seismic design codes present a potential problem for poor dynamic behavior during an earthquake. Methods to upgrade structures and repair structures after earthquakes are important to earthquake hazard mitigation and earthquake engineering. This research project transfers the knowledge and technology developed by Mexico after the September, 1985, Mexico earthquake related to repair and retrofit of structures. The approach is by using the case study method. Documentation of the cases focuses on the design process and the technical approach used. These results are then directly transferable to earthquake hazard mitigation in the United States.
