Lessons Learned from the Failure of Mid-Rise R/C Buildings in the Soviet Armenia Earthquake

本项目对在1988年12月亚美尼亚地震中严重受损的两座中层钢筋混凝土结构进行了详细的地震反应研究。这种结构采用中央核心，楼板向外延伸，也常用于美国的地震地区。将研究弹性和非弹性响应。横向力设计规定将被审查和经济的加强方法将被考虑。本研究将根据观察到的损伤与分析结果的比较，对这类框架系统的动态响应特性提供有价值的信息。在合理的基础上对当前该类结构的设计要求进行验证。

This project conducts a detailed earthquake response study of two midrise reinforced concrete structures which were heavily damaged during the December 1988 Armenia earthquake. Such structures employed a central core with the floor slabs extending outward are also commonly used in seismic regions of the United States. Both the elastic and inelastic responses will be investigated. Lateral force design provisions will be reviewed and economical strengthening methods will be considered. This study will produce valuable information on the dynamic response characteristics of this type of framing system based on the comparison of the observed damage and the analytical results. The current design requirements of this type of structure will be verified on a rational basis.
