CAREER: Integrated Monitoring and Smart Damping for Dynamic Hazard Mitigation

该职业发展计划是一个职业生涯启动活动项目，重点是结构健康监测（SHM）和智能阻尼技术的协同整合，以提供更可靠的结构，更好地应对自然灾害，维护成本更低。 有效地确定灾后行动的优先次序以及长期的安全监测，需要很好地描述土木结构的健康状况。 然而，全球SHM方法在很大程度上是无效的，在检测局部损伤，而本地的方法需要一个成本高昂的传感器数量来监测大型土木结构。 该项目的主旨是一种创新的方法，使用可变刚度和阻尼装置（VSDDs），以引起结构特性的增量变化，增加可用的信息，而无需添加额外的传感器，结果不容易在传统的结构实现。 VSDD还可以显著减轻振动;因此，通过这种集成，VSDD可以用于多种目的，并通过更准确的结构特性更新模型来增强其性能。 一个推广计划，以热情和兴趣未来的工程师将开发使用动手示范和结构设计比赛围绕小型地震模拟器展览在K-12教室为中心。此外，动画和交互式虚拟实验将使用最先进的编程语言，如JAVA和MATLAB设计，以演示结构动力学，监测和控制的方式不可能与静态媒体，如纸张或黑板的关键概念。 这个项目将显着影响PI挑战他成长和成熟的教授，学习和指导。 此外，该项目将促进下一代智能土木工程结构的发展。

This Career Development Plan is a project of career-launching activities focused on the synergistic integration of structural health monitoring (SHM) and smart damping technologies to provide more reliable structures that respond better to natural hazards and are less-costly to maintain. Effective prioritization of post-disaster actions, as well as long-term safety monitoring, requires that the health of civil structures be well characterized. Yet, global SHM methods are largely ineffective in detecting local damage, whereas local methods require a cost-prohibitive number of sensors to monitor large civil structures. The thrust of this project is an innovative approach using variable stiffness and damping devices (VSDDs) to cause incremental changes in structural characteristics, multiplying the available information without adding additional sensors-a result not readily accomplished in a conventional structure. VSDDs can also effect significant vibration mitigation; thus, through this integration, VSDDs can serve multiple purposes, as well as strengthen their performance through more accurate updated models of structural characteristics. An outreach program to enthuse and interest future engineers will be developed using hands-on demonstrations and structural design competitions centered around small-scale seismic simulator exhibitions in K-12 classrooms. Further, animations and interactive virtual experiments will be designed using state-of-the-art programming languages like JAVA and MATLAB to demonstrate key concepts in structural dynamics, monitoring and control in a manner not possible with static media such as paper or chalkboard. This project will significantly impact the PI-challenging him to grow and mature as a professor, to learn and to mentor. Further, the project will facilitate the development of the next generation of intelligent civil engineering structures.
