The United States 5-Story Full-Scale RCM Building Test

在美日联合砖石研究计划的框架内，美国计划的具体目标是开发经过实验验证的设计和分析方法，以确保增强的性能令人满意大范围地震荷载作用下的砖石结构建筑物。特别是，在严重地震荷载下，这样的建筑必须表现出延性性能。美国项目采用的理念的一个关键方面是通过一系列日益复杂的实验来支持设计和分析开发，最终完成对五层全尺寸砖石结构的研究建筑。这项实验对于实现该计划的目标至关重要，因为它将提供对所开发的分析和计算模型的最终验证，并因此将成为在整个项目结束时提出的设计建议的基础。这项研究项目是在加州大学圣地亚哥校区的查尔斯·李·鲍威尔结构系统实验室进行的全面建筑测试。该实验是使用反应墙概念进行的，其中建筑物通过液压致动器以模拟实际地震事件期间的位移的方式在楼层水平上受到生成的位移历史的影响。

Within the framework of the joint U.S.-Japan masonry research program, the specific objective of the U.S. program is to develop an experimentally verified design and analysis methodology that will ensure satisfactory performance of reinforced masonry buildings under a wide range of seismic loadings. In particular, under severe earthquake loadings such buildings must exhibit ductile behavior. A key aspect of the philosophy adopted by the U.S. program is to support the design and analysis development by an increasingly complex set of experiments culminating with the study of a five-story full-scale masonry building. This experiment is essential to achieve the objectives of the program in that it will provide the final validation of the analytical and computational models developed, and thus will form the basis for the design recommendations to be made at the culmination of the overall project. This research project is a full-scale building test conducted at the Charles Lee Powell Structural Systems Laboratory at the San Diego campus of the University of California. The experiment is performed using a reaction wall concept, in which the building is subjected to generated displacement histories at the floor levels via hydraulic actuators in a manner that simulates the displacements during an actual seismic event.
