建筑结构必须能够消散大量的地震能量，才能实现经济的抗震结构。本文介绍了使用焊接三角钢板作为抗震结构附加阻尼和刚度 (ADAS) 装置的有效性的最新研究成果。实验结果表明，正确焊接的钢三角板附加阻尼和刚度装置（TADAS）可以承受大量的屈服逆转，而不会出现任何刚度或强度下降。讨论了 TADAS 单元刚度与裸框架刚度之比以及整个框架屈服强度与 TADAS 单元相关屈服强度之比对附加阻尼和刚度结构的地震响应的影响。基于这些研究，开发了 TADAS 装置在抗震建筑中应用的设计方法和实例。
Building structures must be constructed to dissipate a large amount of seismic energy in order to achieve economical earthquake-resistant constructions. In this paper, recent research findings on the effectiveness of using steel triangular plates welded as the added damping and stiffness (ADAS) device for earthquake-resistant structures are presented. Experimental results indicate that a properly welded steel triangular-plate added damping and stiffness device (TADAS) can sustain a large number of yielding reversals without any stiffness or strength degradation. The effects of the ratio of the TADAS element stiffness to that of the bare frame, and the ratio of the entire frame yield strength to that associated with the TADAS element on the seismic response of the added damping and stiffness structures are discussed. Based on these studies, a design methodology and an example are developed for the application of the TADAS device in earthquake-resistant constructions.
