The objective of this project is to validate the present dynamic characteristics of typical Mexico City buildings and to measure the damping characteristics of these buildings. One steel and four reinforced concrete buildings are chosen and their ambient responses are monitored using seismometers and analog data recorders. These analog measurements of ambient data are uniformly processed and analyzed for spectral characteristics and modal properties. Further, correlation of analytical and experimental results is made to identify good design features, stress distribution in critical elements, torsional effects, effects of in-plane flexibility, and relationship between observed damage and stress intensity.

本项目的目的是验证目前的动态 典型的墨西哥城建筑的特点，并衡量 这些建筑物的阻尼特性。 一钢四 钢筋混凝土建筑物，其环境响应 使用地震仪和模拟数据记录仪进行监测。 这些 均匀地处理环境数据的模拟测量， 分析了频谱特性和模态特性。 此外，本发明还 分析和实验结果的相关性，以确定 良好的设计特征，关键元件中的应力分布， 扭转效应、面内柔度效应和关系 观察到的损伤和应力强度之间的关系
