摘要:
以一30层钢管混凝土框架-核心筒结构为研究对象,在结构不同位置以不同的连接方式设置相同数量的粘滞阻尼器,形成4种减震方案,并进行了三条地震波作用下的弹塑性时程分析,研究结果表明:在大震作用下,与普通钢管混凝土框架-核心筒结构相比,设置了粘滞阻尼器的结构在层间位移角、层剪力和结构耗能等方面均有一定的控制效果;减震控制效果与粘滞阻尼器的设置位置和连接方式有关,将粘滞阻尼器沿高度均匀地设置于核心筒和框架之间时,减震效果最优.在钢管混凝土框架-核心筒结构中设置粘滞阻尼器不同程度地改善了结构的抗震性能,若对阻尼器的设置方式进行优化,将会最大程度地发挥阻尼器的减震效果
Abstract:
In this paper, a 30-storey concrete filled steel tube(CFST)frame-core wall mixed structure is studied, which was set with the same number viscous dampers in different locations of structure and different connection types, then four damping schemes were created. Elastic-plastic time-history analyses are performed on structure with different damping schemes under three seismic waves, whilst the calculation results are studied and analyzed comparatively. The results show that under the strong earthquake action, this structure exerts certain control effect on the aspects of inter-story displacement angle, story shear force and energy dissipation of structure by setting the viscous dampers in CFST frame-core wall structure. The damping effect is influenced by the connection types and the setting locations of dampers, and the damping effect is most obvious when the viscous dampers were set evenly between the column and the core wall along the height of structure. In conclusion, the seismic performance of the structure has been improved. If the setting locations and the connection types of the damper could be optimized, the maximum of the damping effect would be achieved in the design of practical engineering.
