Mechanical Damping for Improved Earthquake Resistance of Structures

研究表明，附加阻尼力是一种有效的减震措施，在地震作用下结构的受力和位移均可减小。结构响应的弹性和非弹性范围。在先前对该主题的调查中，已经确定了几种补充的减振装置的机械特性，并且通过静态和动态实验进行了验证。本项目的主要目标是为识别附加阻尼特性奠定工程基础可以在目前传统设计所提供的基础上，在建筑物的地震反应性能方面提供具有成本效益的改善。这将通过(1)将使用附加阻尼器的建筑成本和地震反应与使用使用当前的规范设计，以及(2)评估阻尼器在整个建筑中分布对性能的重要性，从而评估其易用性设计带有附加阻尼力的建筑物。该项目下的成功研究成果将确保补充减振作为传统设计的可行替代方案得到接受。

It has been demonstrated that supplemental damping can be an effective means for reducing forces and displacements of structures during earthquakes in both the elastic and inelastic ranges of structural response. In prior investigations on the subject the mechanical characteristics of several supplemental damping devices have been established and verified by static and dynamic experiments. The main objective of this project is to establish an engineering basis for identification of supplemental damping characteristics which could provide cost effective improvement in earthquake response performance of buildings above that currently provided by traditional design. This will be accomplished by (1) comparing building cost and earthquake response using supplemental dampers with those using current code designs and (2) assessing the significance of damper distribution throughout the building on performance and consequently on the ease of designing buildings with added damping. Successful research achievement under this project will ensure acceptance of supplemental damping as a viable alternative to traditional designs.
