摘要:
以实际工程为背景建立了附设黏滞阻尼器的框架 - 核心筒结构弹塑性模型.为研究不同地震峰值加速度对黏滞阻尼器耗能效率的影响以及结构减震效率的变化规律,采用7条地震波调整其峰值加速度进行弹塑性动力时程分析.主要讨论了结构的楼层剪力、倾覆力矩、层间位移角、以及结构各部分耗能随地震峰值加速度提高的变化规律.结果表明:多遇地震下结构响应的减幅最大,随着地震强度的提高结构响应的减幅逐渐降低; 阻尼器耗能随地震作用的增加呈线性增长,但阻尼器耗能与地震输入能量的比值在不断降低,导致结构减震效果下降; 地震作用下,黏滞阻尼器为结构提供耗能,减小了结构自身的塑性耗能,对结构起到了保护作用.
Abstract:
Based on the actual engineering background, the elastoplastic model of the frame-core tube structure with viscous damper was established. In order to study the influence of different seismic peak accelerations on the energy dissipation efficiency of viscous dampers and the variation rule of structural damping efficiency, the elastic-plastic dynamic time-history analysis was carried out by using 7 seismic waves to adjust the peak accelerations. The changes of floor shear force, overturning moment, inter-storey displacement angle and the energy dissipation of each part of the structure were discussed with the increase of the peak acceleration.The results show that the damping amplitude of structural response is the largest in frequent earthquakes, and decreases with the increase of seismic intensity. The energy dissipation of the damper increases significantly with the increase of earthquake action, but the ratio of the energy dissipation of the damper to the earthquake input energy decreases continuously, which leads to the decrease of the damping effect of the structure. Under the action of earthquake, viscous damper provides energy dissipation for the structure, reduces the hysteretic energy dissipation of the structure itself, and plays a protective role for the structure.
