NEESR-SG: Performance-Based Design of New Masonry Structures

该奖项是NSF 06-504项目招标“小乔治·e·布朗地震工程模拟研究网络（NEESR）”竞赛的结果。该奖项包括来自德克萨斯大学奥斯汀分校、北卡罗来纳农工大学、加州大学圣地亚哥分校和华盛顿州立大学的参与者。提出的研究有三个相互关联的目标：(1)开发实施新一代基于性能的砌体结构抗震设计所需的技术基础；(2)使用该开发作为加强代码开发人员和建筑社区之间的交互的工具（通常在砌体建筑的创建中起主导作用）；(3)利用这一发展作为一种教育推广机制，旨在提高区域和国家对地震减灾原则和效益的认识。第一个目标将通过对砌体剪力墙和砌体贴面构件的行为进行协调的实验和分析研究来实现，最终将在加州大学圣地亚哥分校的大型室外NEES振动台上进行全尺寸测试。研究结果将用于对当前砌体设计条款提出具体的更新建议，并支持下一代基于概率性能的抗震设计条款。第二个目标将通过与建筑界的一系列推广和交流活动来实现，与上述目标并行进行。第三个目标将通过与K-12和大学一级教育界的一系列外联和交流活动来实现，这些活动与上述每一个目标同时进行。智力优势：该项目集成了现代砌体结构的体系结构、设计和分析，并提供了急需的测试数据来验证和改进建筑规范要求。更广泛的影响：拟议的项目将提供机会，将地震工程的实验和分析研究与实践建筑师和工程师，研究生和本科教育，以及扩大代表性不足群体参与的外展活动结合起来。研究结果将为新砌体结构的抗震设计提供重要的指导，使用下一代基于性能的设计建议。

Abstract 0619096KlingnerThis award is an outcome of the NSF 06-504 program solicitation "George E. Brown, Jr. Network for Earthquake Engineering Simulation Research (NEESR)" competition. This award includes participants from The University of Texas at Austin, North Carolina A&T University, University of California at San Diego, and Washington State University. The proposed research has three linked objectives: (1) to develop the technical groundwork necessary to implement the next generation of performance-based earthquake design of new masonry structures; (2) to use that development as a vehicle for strengthening interactions between code developers and the architectural community (which often plays a leading role in creation of masonry buildings); and (3) to use that development as an educational-outreach mechanism aimed at increasing regional and national awareness of the principles and benefits of earthquake hazard mitigation. The first objective will be achieved by coordinated experimental and analytical studies of the behavior of masonry shear-wall and masonry veneer elements, and will culminate in the full-scale tests on the large outdoor NEES shake table at the University of California, San Diego. Results will be used to propose specific updates to current masonry design provisions and to support the next generation of probabilistic performance-based seismic design provisions. The second objective will be achieved by a series of outreach and communication activities with the architectural community, carried out in parallel with the above. The third objective will be achieved by a series of outreach and communication activities with the K-12 and college-level educational communities, carried out in parallel with each of the above. Intellectual Merit: This project integrates architecture, design, and analysis for modern masonry structures, and provides much-needed test data to validate and improve building code requirements. Broader Impacts: The proposed project will provide the opportunity to integrate experimental and analytical research in earthquake engineering with practicing architects and engineers, with graduate and undergraduate education, and with outreach activities to broaden the participation of under-represented groups. Research results will provide vital guidance for the seismic design of new masonry structures using the next generation of performance-based design recommendations.
