This award is funded under the American Recovery and Reinvestment Act of 2009 (Public Law 111-5).This award is an outcome of the NSF 09-524 program solicitation "George E. Brown, Jr. Network for Earthquake Engineering Simulation (NEES) Research (NEESR)" competition and includes the University of Illinois at Urbana-Champaign (lead institution) and the University of Hawaii at Manoa (subaward) and Ryan-Biggs Associates of Troy, New York (subaward). This project will utilize the NEES equipment site at the University of Illinois at Urbana-Champaign.The research will enable a new technology for earthquake resistant design of buildings, known as hybrid masonry. This innovative concept for improved seismic performance of low to mid-rise buildings located in all earthquake prone areas, including California, relies on the structural action of special reinforced concrete masonry panels that are attached to a conventional steel frame. Interactions with the surrounding steel frame, and novel steel link connectors that can be designed to act as fuses in dissipating seismic energy, make this a promising engineered system for enhancing seismic performance at a reduced cost and impact on the environment. Research will combine large-scale testing with state of the art computational simulation to identify and discover the seismic performance of this new system. Large-scale, two-story hybrid masonry frames will be constructed and tested at the NEES equipment site at Illinois. A complementary set of steel link connector tests will be done at the University of Hawaii. Practitioner interaction is embedded into the research plan through a partnership with Ryan-Biggs Associates, who are currently designing buildings with this new technology and leading seminars to teach other engineers about this innovative system. A well defined technology transfer program with industry partnership will transform research results to earthquake engineering practice so that building owners may benefit from this research. The intellectual merit of the research will include advancements in discovery and understanding of how buildings constructed with hybrid masonry respond to earthquake motions of varying intensities as well as other lateral loadings such as strong winds or blast. The research will advance the art in structural testing since the scale and complexity of the proposed tests will set a new norm for structural masonry research. In addition, the simulation study will set a new mark in modeling mechanics of masonry and its contact with a frame under seismic loadings.With respect to broader impacts, this research will provide building developers and contractors with an economical alternative for building construction applicable to all seismic zones. It will enhance the national economy since building construction will be less expensive, and following earthquakes of the future, less damage, loss of life or business interruptions will occur. The research will also have an impact internationally as this novel new technology is transferred across borders. Moreover, this research will promote teaching of future generations of structural engineers to become more adept at engineering of such structural systems, and broaden participation of underrepresented groups in engineering by engaging them in this research field. Data from this project will be archived and made available to the public through the NEES data repository.

该奖项是根据2009年《美国复苏与再投资法》（公法111-5）资助的。该奖项是NSF 09-524计划征集的结果。纽约特洛伊的瑞安·比格斯（Ryan-Biggs）同事（子宣告）。该项目将利用伊利诺伊大学Urbana-Champaign大学的NEES设备网站。该研究将为建筑物的抗震设计（称为混合砌体）提供新技术。这种创新的概念，用于改善位于包括加利福尼亚在内的所有地震中的低至中层建筑的地震性能，依赖于连接到常规钢框架的特殊钢筋混凝土砌体面板的结构作用。与周围的钢框架的相互作用以及可以设计为耗散地震能量的融合的新型钢连接器，使其成为有前途的工程系统，以降低成本和对环境的影响，以增强地震性能。研究将将大规模测试与最先进的计算模拟结合在一起，以识别和发现该新系统的地震性能。将在伊利诺伊州的NEES设备网站上建造和测试大型两层楼的混合动力砌体框架。 夏威夷大学将进行一套互补的钢连接连接器测试。 通过与Ryan-Biggs Associates建立合作伙伴关系，从业人员的互动嵌入了研究计划，他们目前正在使用这项新技术设计建筑物，并带领研讨会向其他工程师传授有关该创新系统的有关该系统。 通过行业合作伙伴关系，定义明确的技术转移计划将把研究结果转化为地震工程实践，以便建筑所有者可以从这项研究中受益。这项研究的智力优点将包括在发现和理解混合砌体建造的建筑物如何应对不同强度的地震运动以及其他侧向载荷（例如强风或爆炸）方面的进步。这项研究将在结构测试中推进艺术，因为拟议的测试的规模和复杂性将为结构砌体研究树立新的规范。 此外，仿真研究将为砌体的机制建模及其与地震载荷下的框架的接触树立新标记。在更广泛的影响下，这项研究将为建筑开发商和承包商提供适用于所有地震区域的建筑构建的经济替代方案。由于建筑建设将更便宜，因此它将增强国民经济，并且随着未来的地震，损害，损失，损失或业务中断会发生较小的地震。 这项研究还将在国际上产生影响，因为这项新型新技术在跨境转移。此外，这项研究将促进子孙后代的结构工程师的教学，从而更擅长于这种结构系统的工程，并通过使他们参与该研究领域来扩大代表性不足的团体在工程中的参与。该项目的数据将通过NEES数据存储库进行存档并提供给公众。
