项目摘要
Devices such as isolators, dampers and tuned mass dampers are now widely used in the construction industry for earthquake engineering to reduce vibration in new and, in a few cases, existing buildings. However, the use of vibration-control devices is restricted to individual structures, and is therefore too localized to provide larger scale protection from seismic action, which remains an unsolved challenge, especially those in developing countries. Recent disasters, such as those in L'Aquila 2009, Haiti 2010 and Chile 2010 demonstrate the potential benefits that strategies based on vibration control devices could achieve in protecting historical quarters and cities. The proposed research aims to introduce for the first time innovative devices for reducing the vibrations of a group of structures due to seismic action. This will allow alternative strategies to protect cities from earthquakes by reducing the vibrations caused by earthquakes through vibrating barriers (ViBa) hosted in the soil and detached from structures. Vibrating barriers (ViBa) are massive structures tuned to reduce the vibrations of existing structures in the event of seismic action. The approach proposed here therefore represents a step change in seismic vibration control by considering novel non-localised solutions able to reduce the vibrations of a cluster of buildings. The efficiency and effectiveness of the ViBa will be established through theoretical, numerical and experimental studies.
隔震器、阻尼器和调谐质量阻尼器等装置现在广泛应用于建筑行业的地震工程中,以减少新建筑和少数现有建筑的振动。然而,振动控制装置的使用仅限于个别结构,因此过于本地化,无法提供更大范围的抗震保护,这仍然是一个悬而未决的挑战,特别是在发展中国家。最近发生的灾害,如2009年发生在L的阿奎拉、2010年发生在海地和2010年发生在智利的灾害,证明了基于振动控制装置的战略在保护历史街区和城市方面可以实现的潜在好处。这项拟议的研究旨在首次引入创新装置,以减少一组结构在地震作用下的振动。这将使保护城市免受地震的替代战略成为可能,方法是通过驻留在土壤中并与结构分离的振动屏障(VIBA)来减少地震造成的振动。振动屏障(VIBA)是一种巨大的结构,经过调整以减少现有结构在地震作用下的振动。因此,这里提出的方法代表了地震振动控制的一步变化,通过考虑能够减少建筑物群振动的新的非局部解决方案。VIBA的效率和有效性将通过理论、数值和实验研究来确定。
