The particular objectives of this project are: To develop a finite element model of a Segmented Active Constrained Layer treatment. That model will be used as a design tool to optimize material and geometrical parameters of a treatment for a particular structure. To demonstrate the performance of recently developed Segmented Active Constrained Layer method on a full-size floor.Clearly, there is a need for reliable and effective control technique that could adjust to varying external parameters. All these requirements will be satisfied by the proposed system. Actively controlled-segmented constraining layer has the capability of adjusting damper parameters to the external conditions at hand. The system will be easy to install both in newly constructed and in existing structures. It will also have a limited fail-safe capability. The constrained viscoelastic layer will provide a certain level of damping even in the case of power failure.

该项目的具体目标是： 开发分段主动约束层处理的有限元模型。 该模型将用作设计工具，以优化特定结构处理的材料和几何参数。 为了展示最近开发的分段主动约束层方法在全尺寸地板上的性能。显然，需要可靠且有效的控制技术来适应不同的外部参数。 所提出的系统将满足所有这些要求。 主动控制分段约束层能够根据当前的外部条件调整阻尼器参数。 该系统很容易安装在新建和现有结构中。 它还具有有限的故障安全能力。 即使在断电的情况下，约束粘弹性层也将提供一定程度的阻尼。
