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.

本项目进行了详细的地震反应研究， 两座钢筋混凝土结构的中层建筑， 1988年12月亚美尼亚地震中受损。 等 建筑物采用了一个中心核心与楼板 在地震区， 美国的 将研究弹性和非弹性响应。 将审查横向力设计规定， 将考虑经济的加固方法。 这项研究将产生有价值的信息， 这种框架系统的响应特性 根据观察到的损坏和分析结果的比较， 结果 这种类型的当前设计要求 结构将在合理的基础上进行验证。
