S/C: Hysteretic Mass Dampers for Vibration Control

9302101凯利轻阻尼结构系统受到风或地震激励的动态性能可以显着提高调谐质量阻尼器（TMD）的使用。 本项目的目标是开发一种创新的多学科方法，通过使用机械装置，提供三角形磁滞回线作为TMD系统中的能量耗散手段的质量阻尼。 为了通过主动控制增强性能，将评估这些滞后质量阻尼器的真实的时间调谐机制。 这些目标包括：（i）鉴定在地震和风激振下的质量阻尼器系统的最佳滞后;（ii）发展半主动控制技术，以进一步提高质量阻尼性能;及（iii）建造实现最佳滞后性能的装置，并通过地震模拟器测试验证建筑系统性能。 滞后机械装置的建造将由两家商业公司提供支持。 为了实现这两个目标，进行这项工作的研究小组将使用概念和计算技术与严格的实验建模技术相结合的组合。 该计划的所有研究和开发将由执业工程师和学术研究人员共同努力提供。***

9302101 Kelly The dynamic performance of lightly damped structural systems subjected to wind or earthquake excitation can be significantly enhanced by the use of tuned mass dampers (TMD). The objective of this project is to develop an innovative multidisciplinary approach to mass damping through the use of mechanical devices which provide triangular hysteresis loops as a means of dissipating energy in TMD systems. For enhanced performance through active control, real time tuning mechanisms for these hysteretic mass dampers will be evaluated. The goals include: (i) identification of optimal hysteresis for mass dampers systems under seismic and wind excitation; (ii) development of semi active control techniques to further enhance mass damping performance; and (iii) construction of devices implementing the optimal hysteretic behavior and verification building system performance by earthquake simulator testing. Support for the construction of the hysteretic mechanical devices will be provided by two commercial firms. To accomplish both of these objectives the research team conducting this work will use a combination of conceptual and computational techniques combined with rigorous experimental modeling techniques. All research and development for this program will be provided by a collaborative effort of both practicing engineers and academic researchers. ***
