SGER to Enable GOALI CMS-0324522 Utilization of NEES ES Capabilities

摘要：本提案的目的是在加州大学圣地亚哥分校NEES场地的大型振动台上建造一个预制混凝土停车场结构部分的近似半比例模型。这是对亚利桑那大学、加州大学圣地亚哥分校和利哈伊大学合作进行的其他测试和分析研究的重要补充。美国几次地震后的实地调查表明，这种结构体系通常对地震荷载的抵抗力很差。这项研究是一个紧密结合的分析和实验工作，旨在显着推进地震期间预制楼板横隔梁的抗震性能的基础知识。这是一个非常复杂的系统下的动态负载，是一个非常流行的结构系统的某些类型的结构。这项分析和实验工作旨在显著提高对预制楼板横隔梁抗震性能的认识，其具体目标是为最终的规范实施提供适当的抗震设计方法。这一目标是通过一个活跃的行业工作组的定期投入实现的，该工作组在守则编写机构中有很强的存在。

Abstract: The objective of this proposal is to build an approximately half-scale model of a section of a precast concrete parking structure on the large-scale shake table at the NEES site at the University of California-San Diego. This is an important addition to other tests and analytical studies being conducted cooperatively at the University of Arizona, UCSD and Lehigh University. Field surveys after several U.S. earthquakes have shown that this structural system often provides poor resistance to seismic loads. The research is a closely integrated analytical and experimental effort intended to significantly advance fundamental knowledge of the seismic behavior of precast floor diaphragms during earthquakes. This is a very complex system under dynamic loads and is a very popular structural system for certain types of structures. This analytical and experimental effort intended to significantly advance knowledge of the seismic behavior of precast floor diaphragms with the specific objective of producing an appropriate seismic design methodology for eventual code implementation. This objective is realized through regular input from an active industry task group with a strong presence on code-writing bodies.
