考虑阻尼器破坏影响的结构时程分析

Time-history Analysis of Buildings Structure Considering the Influence of Viscous Damper Failure

随着社会的不断进步和城市土地供应紧张,城市中高层建筑不断出现,而且超高层建筑在经济发达,人口密集地区需求激增。结构震动控制技术被广泛应用在超高层建筑中,且已经取得了较好的抗震效果。其中被动控制技术由于研究时间比较长,理论也比较成熟,已经被广大科研人员和生产一线的结构设计工程师接受,大量应用于各地的高层建筑结构当中。文章主要研究被动控制技术之一的粘滞阻尼器在地震过程中发生破坏后,对结构损伤的影响。研究结果表明:一般情况下,当结构遭受地震中度破坏后,粘滞阻尼器将发生破坏,进而对结构损伤有较大影响。

With the continuous progress of society and the tight supply of urban land, the high-rise buildings in the city are constantly emerging, and the demand for super high-rise buildings has surged in the developed and densely inhabited district. Structural vibration control technology is widely used in super high-rise buildings, and has achieved a good seismic effect. The theory of passive control technology is relatively mature for it has been studied for a long time, which has been accepted by a large number of scientific research personnel and structural design engineers in high-rise building structures. This article mainly studies the effect of the viscous damper, one of the passive control technologies, on the structural damage after the earthquake.The results show that： In general, when the structure is damaged by moderate earthquakes, the viscous damper will be destroyed, which will have a great impact on the structural damage.
