摘要

对粘滞阻尼器在小位移条件下的力学行为进行了试验研究,研究表明,阻尼器在小行程条件下其阻尼力小于理论模型给出的计算结果,建议在实际工程应用中考虑阻尼器在小行程条件下的力学特性以及影响因素,以确保真正实现阻尼器在小行程条件下也能发挥有效的减震消能作用,提高结构的抗震能力。
The main point of this paper is an experimental mechanic research on viscous damper under the condition of minor stroke.The result reveals the difference between experiment and calculation by formula of mathematical model is significant.The behavior of insufficient stiffness of Maxwell model is another considerable point during the situation of minor to medium intensity earthquake.By the results of this study,the behavior of a damper under the minor displacement of a real structure must be considered for ensuring the effect of reducing seismic activity by utilize the damper as a supplemental energy dissipation devices.
