The design of floor structures supporting human occupants is increasingly being governed by vibration serviceability criteria. This is a result of increasing slenderness of modern floor systems and the trend for fewer partitions and other non-structural elements that otherwise would provide damping. At the same time, demands for better vibration performance are increasing. Occupants of high quality commercial, residential and hospital buildings will complain when excessive levels of vibration are felt. Also, many new items of scientific, healthcare and manufacturing equipment are sensitive to even very low levels of vibration and the structures that support them must be designed to ensure an appropriate vibration environment.To address these issues, the proposed research will investigate the use of active vibration control (AVC) to improve the vibration performance of floor structures under human-induced loading. This technology has already been shown by the PI to be feasible but it requires substantial further research to be established as a practical option for structural engineers and building developers. Hence, the key aims of the proposed research are:- To identify and develop control strategies suitable for active control of human-induced vibrations in floors and to evaluate improvements in floor vibration performance through simulations, laboratory testing and field installation. A full spectrum of complexity will be investigated, ranging from simple single-input-single-output collocated systems to much more complex adaptive model-based systems using multiple sensors and actuators.- To develop inertial actuation technology appropriate for AVC on floor structures, and hence to demonstrate that an AVC system can be `packaged' to be affordable, compact, robust and reliable. These are key technological hurdles that must be addressed if the benefits of AVC systems are to be realised in the highly commercial civil engineering sector.

支持人类乘员的地板结构的设计越来越受振动服务标准的控制。这是现代地板系统的细长性的增加以及较少的分区和其他非结构性元素的趋势，否则会提供阻尼。同时，对更好的振动性能的需求正在增加。当感觉到过多的振动水平时，高质量商业，住宅和医院建筑物的居民将抱怨。此外，许多新项目的科学，医疗保健和制造设备对振动的水平也很敏感，并且必须设计支持它们的结构以确保适当的振动环境。要解决这些问题，拟议的研究将调查使用活动振动控制（AVC）以改善人类诱导的负载下地板结构的振动性能。 PI已经证明了这项技术是可行的，但是它需要对结构工程师和建筑开发人员的实用选择建立大量研究。因此，拟议的研究的主要目的是： - 确定和制定适合主动控制地板中人类诱发振动的控制策略，并通过模拟，实验室测试和现场安装来评估地板振动性能的改进。将研究各种复杂性，从简单的单输入单输出 - 输出共处系统到使用多个传感器和执行器的更复杂的基于自适应模型的系统。如果要在高度商业的土木工程领域实现AVC系统的好处，则必须解决这些关键技术障碍。
