NEESR: Seismic Performance of Conventional and Innovative Special Structural Walls

在美国和世界范围内，从基础到建筑屋顶的钢筋混凝土结构墙是用来抵抗地震力量的最常见的结构系统之一。在许多建筑物中，这些墙围绕着楼梯和电梯或位于建筑物的外围。墙体设计和施工实践的发展导致了更薄、更高效的墙体几何形状，推动了这种结构系统的抗震性能极限。事实上，在最近的一些地震和结构工程实验室测试中的糟糕表现表明，现在有必要修改抗震设计实践，以确保未来的建筑符合现代建筑的高性能期望。本研究将探讨结构墙的抗震设计和性能限制，同时考虑传统和创新的墙体施工实践。该研究将调查：(a)力学模型，以了解传统建筑的不良性能；(b)创新而实用的新系统，可以改变设计实践；(c)传统和创新系统的基于性能的设计限制；(d)国际合作开发和解释全尺寸三维建筑结构的振动台测试。这项研究是加州大学洛杉矶分校和加州大学伯克利分校的研究人员共同努力的结果。初步测试将在加州大学伯克利分校和伊利诺伊大学厄巴纳-香槟分校的小乔治·e·布朗地震工程模拟网络（NEES）设施进行。此外，该项目团队将与来自东京大学和日本国家地球科学与防灾研究所的研究人员合作，他们将在日本三木的E-Defense震动台设施上进行全面的建筑测试。该项目的数据将存档，并通过NEES项目仓库/数据存储库（http://www.nees.org）向公众提供。该研究项目解决了一个重要的和具有挑战性的问题，将推进发现和理解用于抵抗地震力量的最常见的建筑系统之一。研究结果将以多种方式传播：利用NEES资源共享结果，让地震专业人员参与，以及传播教育材料。研究结果将最直接地造福社会，因为它有助于为高效和高性能的建筑结构确定适当的抗震设计要求。这些目标将通过研究人员与专业组织的积极参与和利用由积极参与地震工程的专家工程专业人员组成的咨询委员会来实现。研究生和本科生的体验将通过积极参与研究、参与大学之间的合作、与日本研究人员的合作以及与设计专业人士的互动而得到加强。该奖项是国家减少地震灾害计划（NEHRP）的一部分。

Solid reinforced concrete structural walls that span from the foundation to the building roof are one of the most common structural systems used to resist earthquake forces in the United States and worldwide. In many buildings, these walls surround stairs and elevators or are located at the building perimeter. Evolution in wall design and construction practices has resulted in thinner, more efficient wall geometries that are pushing the seismic performance limits of this structural system. Indeed, poor performance in some recent earthquakes and structural engineering laboratory tests demonstrate that revisions in seismic design practices now are necessary to ensure that future construction meets the high performance expectations for modern construction. This research will explore seismic design and performance limits for structural walls, considering both conventional and innovative wall construction practices. The research will investigate: (a) mechanics models to understand poor performance of conventional construction, (b) innovative yet practical new systems that can transform design practices, (c) performance-based design limits for conventional and innovative systems, and (d) international collaborative development and interpretation of shake table tests of full-scale, three-dimensional building structures. This research is a collaborative effort among researchers at the University of California at Los Angeles and University of California at Berkeley. Primary tests will be conducted at the George E. Brown, Jr. Network for Earthquake Engineering Simulation (NEES) facilities at the University of California at Berkeley and University of Illinois at Urbana-Champaign. In addition, the project team will collaborate with researchers from the University of Tokyo and Japan's National Research Institute for Earth Science and Disaster Prevention, who will conduct full-scale building tests on the E-Defense shake table facility in Miki, Japan. Data from this project will be archived and made available to the public through the NEES Project Warehouse/data repository (http://www.nees.org). The research program tackles an important and challenging problem that will advance discovery and understanding of one of the most common building systems used to resist earthquake forces. The results of the research will be disseminated in multiple ways: by sharing results using NEES resources, by involving earthquake professionals, and by disseminating educational materials. The results will benefit society most directly by helping define appropriate seismic design requirements for efficient and high-performance building construction. These goals will be accomplished by the active participation of the researchers with professional organizations and by utilizing an advisory board of expert engineering professionals actively involved in earthquake engineering. Graduate and undergraduate student experiences will be enhanced by active participation in research and by collaboration among the participating universities, with Japanese researchers, and interactions with design professionals. This award is part of the National Earthquake Hazards Reduction Program (NEHRP).
