项目摘要
There is an inexorable trend for civil engineering structures to become more slender and lightweight, as engineers strive to design more efficient structures with reduced economic cost, reduced carbon footprint and increased flexibility of usage. Unfortunately, due to their reduced mass and stiffness these structures are inherently lively and there is a desperate need for advanced technologies that are capable of ensuring satisfactory vibration performance when people walk, run and jump on them. There are two key issues to address:(1) Technologies are required to deal with existing vibration problems, which are increasingly and widely observed in structures such as floors, footbridges, sports stadia and staircases. Currently available technologies are insufficient to deal with the majority of these problems, which means that extensive and low-tech structural modification schemes have to be employed that are both expensive and highly disruptive.(2) If the ambitions of structural engineers for ever more slender and efficient structures are to be realised, it will be necessary to 'design in' advanced methods of vibration control when developing new structures. This is because many contemporary structures are already being designed at their limits of vibration acceptability. Unfortunately, the new technologies required for this transformative design approach are not yet available.In the last five years, the applicant and his team have carried out exciting research into active control of vibration in floor structures, in which large reductions in vibration have been achieved that are not possible using other floor control technologies. They have also demonstrated that significant material savings may be made using this technology, which has the potential to significantly reduce the carbon footprint of new buildings. This is the main vision for this fellowship and the future, where advanced and intelligent vibration control strategies will become commonplace in structures subject to human dynamic loading.However, a solution that works for floor vibrations from a single person walking is not necessarily going to work for a sports stadium with many thousands of people jumping during a rock concert. Hence, what is required is a required is a complete 'suite' of control technologies, from which the most appropriate solution may be chosen and implemented for any particular vibration problem. In these days of active noise cancelling headphones and semi-active vehicle suspension systems, it is time for these advanced technologies to find their place in civil structural engineering, to solve the unique problems of human-induced vibration.Hence, in this research a comprehensive framework of technologies will be developed, so that the most appropriate technologies may be selected for a particular application. This will be the first time in the world that such a holistic approach has been taken to mitigation of human-induced vibrations. Fundamental research into a range of these technologies, including active, semi-active and hybrid vibration control techniques will be carried out to prove their viability in the civil engineering sector through analytical modelling, laboratory testing and in-the-field implementation. Finally, extensive industrial liaison and public outreach activities are planned to ensure the take-up of these technologies, which is the key way in which this research will benefit UK plc.
土木工程结构变得更加细长和轻量化是一个不可阻挡的趋势,因为工程师努力设计更高效的结构,以降低经济成本、减少碳足迹并提高使用灵活性。不幸的是,由于质量和刚度降低,这些结构本质上是活跃的,因此迫切需要先进的技术来确保人们在其上行走、跑步和跳跃时获得令人满意的振动性能。有两个关键问题需要解决:(1)需要技术来解决现有的振动问题,这些问题在地板、人行天桥、体育场馆和楼梯等结构中越来越广泛地观察到。目前现有的技术不足以解决其中的大多数问题,这意味着必须采用广泛且技术含量低的结构改造方案,既昂贵又具有高度破坏性。(2)如果结构工程师的野心变得更加渺茫要实现高效的结构,在开发新结构时,有必要“设计”先进的振动控制方法。这是因为许多当代结构的设计已经达到了振动可接受的极限。不幸的是,这种变革性设计方法所需的新技术尚不可用。在过去的五年中,申请人和他的团队对楼板结构振动的主动控制进行了令人兴奋的研究,其中已经实现了振动的大幅减少这是使用其他楼层控制技术无法实现的。他们还证明,使用这项技术可以节省大量材料,从而有可能显着减少新建筑的碳足迹。这是本次研究金和未来的主要愿景,先进和智能的振动控制策略将在承受人体动态载荷的结构中变得司空见惯。然而,适用于单人行走引起的地板振动的解决方案不一定行得通。在摇滚音乐会期间有数千人跳跃的体育场。因此,我们需要的是一套完整的控制技术“套件”,从中可以针对任何特定的振动问题选择和实施最合适的解决方案。在主动降噪耳机和半主动车辆悬架系统出现的今天,是时候让这些先进技术在土木结构工程中找到自己的位置,解决人为振动的独特问题了。因此,在这项研究中,全面将开发技术框架,以便为特定应用选择最合适的技术。这将是世界上首次采用这种整体方法来减轻人为振动。将针对一系列这些技术(包括主动、半主动和混合振动控制技术)进行基础研究,以通过分析建模、实验室测试和现场实施来证明其在土木工程领域的可行性。最后,计划开展广泛的工业联络和公共宣传活动,以确保这些技术的采用,这是这项研究使英国公司受益的关键方式。
