The research objective of this award is provide critical experimental data and assessment tools essential for evaluating the integrity of common steel gravity load resisting systems. A combination of system testing and component testing will be used to assess the behavior of these systems as designed today. These experimental results will then be used to advance models for the analysis of such systems under large deformations and to identify critical details that have a major impact on system performance. Cost-effective details that transform performance will be developed and tested at the component level and then incorporated in system tests. At the component level, steel connections will be tested under combined rotation and tension loading, and important details of the slab on deck system, such as lap splices, beam anchorage, and the tensile behavior of the slabs on metal decks in orthogonal directions will be tested. System tests will involve large-scale push-down tests of gravity frame systems using current practice details and new concepts developed in this research.The results of this research will directly impact the safety of almost all steel buildings by assessing the integrity of ubiquitous structural components and developing models for engineers to employ. It will also develop transformative solutions for improving the robustness of common gravity frame components and systems. Through close collaboration with the American Institute of Steel Construction, expedient dissemination and rapid implementation will be facilitated. Graduate students will be directly trained through this research as they address the challenges associated with unanticipated structural loadings. Interest and diversity in engineering will be enhanced through partnerships with the Summer Undergraduate Research Fellowship (SURF) program at Purdue, the Summer Research Opportunity Program (SROP) at Illinois and the Seattle Mathematics Engineering Science and Achievement Program (Seattle MESA) at Washington. These programs will provide for undergraduate (SURF and SROP) and high school (MESA) research internships.

该奖项的研究目标是提供关键的实验数据和评估工具，对于评估公共钢重力载荷系统的完整性至关重要。 系统测试和组件测试的组合将用于评估当今设计的这些系统的行为。 然后，这些实验结果将用于推进模型，以在大变形下分析此类系统，并确定对系统性能产生重大影响的关键细节。 具有成本效益的细节将在组件级别开发和测试转换性能，然后将其纳入系统测试。在组件级别，将在组合旋转和张力载荷下测试钢连接，以及甲板系统上平板的重要细节，例如圈接头，梁锚固和正交方向上金属甲板上板的拉伸行为测试。系统测试将使用当前的实践细节和本研究中开发的新概念进行重力框架系统的大规模推入测试。本研究的结果将直接通过评估无处不在的结构组件的完整性直接影响所有钢结构的安全性并开发工程师的模型。 它还将开发变革性解决方案，以改善公共重力框架组件和系统的鲁棒性。 通过与美国钢结构研究所的密切合作，将促进权宜之计的传播和快速实施。 研究生将通过这项研究直接接受培训，因为他们应对与意外结构负荷相关的挑战。通过与普渡大学的夏季本科研究奖学金（SURF）计划，伊利诺伊州的夏季研究机会计划（SROP）以及西雅图数学工程科学与成就计划（Seattle Mesa）的夏季本科研究奖学金计划（SROP）与夏季本科研究奖学金计划（SROP），将增强对工程学的兴趣和多样性。这些计划将为本科（Surf和Srop）和高中（MESA）研究实习提供。
