Structural walls, which are solid concrete walls commonly used in buildings around stairwells and elevators, are used worldwide because they are economical to construct, efficient to separate spaces, and effective in protecting buildings from strong earthquake ground shaking. Unexpected damage that occurred to structural walls in recent earthquakes, e.g., Chile in 2010 and New Zealand in 2011, as well as damage observed in recent laboratory tests in the United States and Japan, suggest that structural engineers have pushed seismic design limits for structural walls beyond a critical boundary. Despite these observations, engineers are increasingly choosing to use structural walls because, historically, structural wall buildings are less likely to collapse in earthquakes and are more likely to limit heavy damage to building contents. Given recent observations, considerable research on the seismic performance and design of structural walls has been initiated or is planned in the United States and around the world. Many of the research needs identified for structural walls require large-scale laboratory testing to validate and calibrate computational models and to develop and refine seismic design recommendations for building codes. Large-scale testing is expensive; therefore, the ability of any one country to address the breadth of issues that have been identified is limited and progress will be slow. Given the critical research needs for structural walls and the limited resources available to individual countries, this award will facilitate international research collaborations using both in-person meetings and virtual collaboration tools by creating a virtual international institute for the seismic performance assessment of structural wall systems. Through this institute, researchers from Chile, Japan, New Zealand, and the United States, who have a long history of both informal and formal research collaboration, will share research test plans and test data; develop, improve, calibrate, and validate component and system models used for building design; achieve consensus, where possible, on critical performance issues; prepare joint reports, papers, and design recommendations; and develop collaborative new research directions. Institute results will be disseminated by members participating in meetings, workshops, and code committees, by involving earthquake professionals, by developing and distributing educational materials and project results (e.g., data), and by creating a project web site. Mentoring and training of young researchers (students and faculty) will be enhanced through participation in both face-to-face meetings and virtual collaboration with leading researchers and practitioners from around the world. The broader U.S. and international earthquake engineering research community will benefit from joint publications, access to data, and opportunities for enhanced collaboration (in-person and virtual). This award is designated as a Science Across Virtual Institutes (SAVI) award and is co-funded by NSF's Directorate for Engineering and NSF's Office of Integrative and International Activities.

在楼梯间和电梯周围建筑物中常用的固体墙壁是在全球范围内使用的固体墙壁，因为它们是经济的，可以构造，有效地分离空间，并且有效地保护建筑物免受强烈地震地面的震动。 最近地震中的结构墙发生了意外的破坏，例如2010年的智利和2011年的新西兰，以及在美国和日本最近的实验室测试中观察到的损害，这表明结构工程师已将结构墙的地震设计限制推向关键边界以外的结构墙。 尽管有这些观察，工程师越来越多地选择使用结构墙，因为从历史上看，结构性墙壁建筑物在地震中的可能性较小，并且更有可能限制对建筑物内容物的严重破坏。 鉴于最近的观察，在美国和世界各地已经启动或计划了有关结构墙的地震性能和设计的大量研究。 确定的结构墙的许多研究需求需要大规模的实验室测试，以验证和校准计算模型，并开发和完善建筑法规的地震设计建议。大规模测试很昂贵；因此，任何一个国家解决已确定的问题广度的能力是有限的，进步将很慢。鉴于对结构墙的关键研究需求以及各个国家可用的资源有限，该奖项将通过建立虚拟国际国际研究所对结构墙系统的地震绩效评估来促进国际研究合作。 通过该研究所，来自智利，日本，新西兰和美国的研究人员在非正式和正式研究合作方面都有悠久的历史，他们将分享研究测试计划和测试数据；开发，改进，校准和验证用于建筑设计的组件和系统模型；在可能的情况下，就关键绩效问题达成共识；准备联合报告，论文和设计建议；并制定合作新的研究方向。 通过参与地震专业人员，开发和分发教育材料和项目结果（例如数据）以及创建项目网站，通过参与会议，研讨会和代码委员会的成员将通过参与会议，研讨会和代码委员会的成员传播研究所的结果。 通过参加面对面的会议以及与世界各地的主要研究人员和从业人员的虚拟合作，将增强对年轻研究人员（学生和教师）的指导和培训。 更广泛的美国和国际地震工程研究界将受益于联合出版物，数据访问以及增强协作的机会（面对面和虚拟）。 该奖项被指定为虚拟机构（SAVI）奖的一项科学，并由NSF的工程局和NSF综合和国际活动办公室共同资助。
