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

该项目对1988年12月亚美尼亚地震中严重受损的两个中高钢筋混凝土结构进行了详细的地震反应研究。这种结构采用中心核心，楼板向外延伸，在美国地震区也经常使用。弹性和非弹性响应都将被研究。将审查侧向力设计条款，并考虑经济的加固方法。这项研究将根据观测到的损伤与分析结果的比较，为该类型框架体系的动力响应特性提供有价值的信息。目前这类结构的设计要求将在合理的基础上进行核实。

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.
