项目摘要

This PECASE award combines multi-disciplinary, multi-scale, research and education programs to study the innovative use of shape-memory alloys (SMAs) as seismic dampers in Civil engineering structures. Shape memory alloys are a class of alloys that display several unique characteristics, including high damping characteristics. The research program ranges from micro-scale studies to full-scale proof-of-concept experimental tests. The research plan has the following tasks: (1) Determine the effects of thermo-mechanical heat treatment on the mechanical properties of shape memory alloys; (2) Develop SMA-based passive dampers for use in seismic resistant design and retrofit; (3) Develop analytical models for SMAs; (4) Conduct full-scale tests of structures with SMA dampers; and (5) Develop code procedures for using shape memory alloy dampers.The integration of research and education is accomplished through a Research Experience for Undergraduates program in the area of "smart materials." Students from interdisciplinary fields such as materials science, mechanical engineering, as well as civil engineering will work collaboratively on both experimental and analytical aspects of the applications of smart materials.The research will provide a unique database of experimental results on large-scale shape memory alloy material, which can be used as a basis for the development of a new family of innovative energy dissipating devices. The research will also lead to the development of analytical tools and methodologies to allow practicing engineers to determine potential benefits of a variety of applications of shape memory alloys. Finally, the research will lead to code development and implementation for using shape memory alloys in Civil Engineering structures. In light of the recent economic losses in major earthquakes, this research will lead to innovative, simple, and highly effective methods for seismic rehabilitation of structures.
该 PECASE 奖项结合了多学科、多规模的研究和教育项目,旨在研究形状记忆合金 (SMA) 作为土木工程结构抗震阻尼器的创新应用。 形状记忆合金是一类具有多种独特特性的合金,包括高阻尼特性。 研究计划范围从微观研究到全面的概念验证实验测试。 研究计划有以下任务:(1)确定形变热处理对形状记忆合金力学性能的影响; (2) 开发基于SMA的被动阻尼器,用于抗震设计和改造; (3) 开发 SMA 分析模型; (4) 对带有SMA阻尼器的结构进行全尺寸试验; (5) 开发使用形状记忆合金阻尼器的代码程序。研究和教育的整合是通过“智能材料”领域的本科生研究经验项目实现的。 来自材料科学、机械工程以及土木工程等跨学科领域的学生将在智能材料应用的实验和分析方面进行合作。该研究将为大规模形状记忆合金材料的实验结果提供一个独特的数据库,可作为开发一系列新型创新耗能装置的基础。 该研究还将促进分析工具和方法的开发,使实践工程师能够确定形状记忆合金各种应用的潜在好处。 最后,该研究将导致在土木工程结构中使用形状记忆合金的代码开发和实施。 鉴于最近大地震造成的经济损失,这项研究将带来创新、简单且高效的结构抗震修复方法。
