A 5-story full-scale reinforced masonry research building test is undertaken in this project. This is the final research project under the TCCMAR program which will enable the limit state masonry design guideline and analytical model verification to be completed. The research building under testing consists of a 5-story coupled shear wall structure which will allow a ductile system behavior while providing a complex test bed for so far unanswered analytical and design model verification in areas such as effective width of flanged walls and floor diaphragms, coupling effects of floors, as well as higher mode effects on design shear forces. The experiments will be conducted in the Charles Lee Powell Structural Laboratory at the University of California, San Diego using the pseudo-dynamic testing facilities. The basic objectives of the research are to test the TCCMAR design philosophy and recommendation for seismic reinforced masonry structures and provide a viable experimental verification of the analytical procedures developed. The research will also provide insight into the higher mode effects as they are encountered in some of the current design practice. It is also expected to contribute to the development of repair, retrofit and strengthening measures for existing masonry structures. This project is the capstone of the TCCMAR Program which will be drawn into a successful completion with this project and the concurrent effort in developing the limit state design standards underway through a separate companion project.

本工程进行了一栋5层全尺寸加筋砌体研究建筑试验。这是TCCMAR项目下的最后一个研究项目，将使砌体极限状态设计指南和分析模型验证得以完成。正在测试的研究大楼由一个5层的耦合剪力墙结构组成，该结构将允许延性系统行为，同时提供一个复杂的测试平台，用于迄今为止尚无答案的分析和设计模型验证，例如法兰墙的有效宽度而楼板隔板、楼板的耦合效应，以及高模态效应对设计剪力的影响。实验将在加州大学圣地亚哥分校的查尔斯·李·鲍威尔结构实验室进行，使用伪动力测试设备。本研究的基本目标是测试TCCMAR抗震加固砌体结构的设计理念和建议，并为所开发的分析程序提供可行的实验验证。​该研究还将提供对当前一些设计实践中遇到的更高模式效应的见解。预计它还将有助于制定现有砖石结构的修理、改造和加强措施。该项目是TCCMAR项目的顶点，该项目将通过一个单独的伙伴项目成功完成，并同时努力制定正在进行的极限状态设计标准。
