项目摘要
The primary research objective of this project is to investigate the behavior and design of reinforced concrete (RC) wall structures under elevated temperatures due to fire. To achieve this objective, the research will: (1) experimentally investigate the out-of-plane axial-load-moment-curvature-temperature behavior of RC wall cross sections under elevated temperatures; (2) evaluate the effects of geometric, material, reinforcement, and loading parameters on these structures; and (3) develop a rational, predictive fire-resistant structural design procedure based on the test results. The project will result in experimental evidence demonstrating the fire performance of RC walls and validated design models using the test data. In addition, the experiments will investigate the application of a cost-effective test method using ceramic fiber radiant heaters to subject the specimens to elevated temperatures. The ultimate project deliverables will be the ability to evaluate the structural performance of a RC wall under fire and the ability to design a wall that can withstand uncontrolled fires until burnout. The successful completion of the project tasks will provide important data for fire-resistant design of reinforced concrete walls commonly used in building structures, with ancillary contributions to fire engineering and materials engineering/science fields. Wall structures designed using this information will facilitate emergency response activities by protecting elevator cores and stairwells, and contribute towards the resistance of buildings to prevent catastrophic overall collapse. The project will train a graduate student in fire resistant design of structures and encourage undergraduate students to study structural fire engineering, strongly focusing on underrepresented groups. The researchers will utilize the project to educate future engineers through K12 activities as well. The research results will be disseminated widely for utilization by practicing engineers, other researchers, and other end users.
本计画的主要研究目的是探讨钢筋混凝土墙结构在火灾高温下的行为与设计。为了实现这一目标,本研究将:(1)试验研究高温下RC墙截面的平面外轴向荷载-弯矩-曲率-温度行为;(2)评估几何、材料、钢筋和荷载参数对这些结构的影响;(3)根据试验结果制定合理的、可预测的耐火结构设计程序。该项目将产生实验证据,证明钢筋混凝土墙的防火性能和使用测试数据验证的设计模型。此外,实验将研究一种具有成本效益的测试方法的应用,使用陶瓷纤维辐射加热器使试样经受高温。最终的项目交付成果将是评估火灾下钢筋混凝土墙的结构性能的能力,以及设计能够承受不受控制的火灾直到烧毁的墙的能力。项目任务的顺利完成,将为建筑结构中常用的钢筋混凝土墙体的防火设计提供重要数据,并对消防工程和材料工程/科学领域做出辅助贡献。利用这些信息设计的墙体结构将通过保护电梯核心和楼梯间来促进应急响应活动,并有助于建筑物的抵抗力,以防止灾难性的整体倒塌。该项目将培训一名研究生进行结构防火设计,并鼓励本科生学习结构防火工程,重点关注代表性不足的群体。研究人员还将利用该项目通过K12活动教育未来的工程师。研究结果将被广泛传播,供实践工程师、其他研究人员和其他最终用户使用。
