结构的振动控制通常通过诸如隔振器、阻尼器和调谐质量阻尼器等装置来解决。虽然这些装置在技术上是合理的，但在现有建筑物中使用它们可能不切实际，例如遗产结构，而由于各种社会经济问题，禁止改变部分结构。在这种情况下，最近提出了一种称为振动屏障（ViBa）的新型被动控制装置。振动屏障是一个巨大的结构，托管在土壤中，并从现有的建筑物分离，校准吸收部分地面运动输入能量。振动屏障的工作原理是基于结构-土-结构相互作用的原理，本文设计了振动屏障来控制在地震动加速度作用下的砌体结构的振动。结构、土壤和ViBa被假定为线性行为，并通过相关的有限元方法进行建模。设计是通过一个简化的离散模型的结构和ViBa的土壤是由线性弹性弹簧。动态响应的显着减少已经实现了表现的潜力，振动屏障是一个有效的替代，而传统的振动控制技术不能应用。
Vibration control of structures is normally addressed through devices such as isolators, dampers and tuned mass dampers. Although those devices are technically sound their use might become unpractical in existing buildings such as heritage structures, whereas the alteration of part of the structure is forbidden for various socio-economic issues. In this context, a novel passive control device called Vibrating Barrier (ViBa) has been recently proposed. The Vibrating Barrier is a massive structure, hosted in the soil and detached from the existing building, calibrated for absorbing portion of the ground motion input energy. The working principle is based on the generally know structure-soil-structure interaction between two vibrating structures and the soil.In this paper the Vibrating Barrier is designed to control the vibration of an existing masonry structure forced by ground motion acceleration. The structure, the soil and the ViBa are assumed to be linear behaving and modelled through a pertinent Finite Element approach. The design is pursued through a simplified discrete model of the structure and the ViBa in which the soil is represented by linear elastic springs. Significant reduction of the dynamic response has been achieved manifesting the potential of the Vibrating Barrier to be a valid alternative whereas the traditional vibration control techniques cannot be applied.
