双层柱面网壳的减震性能研究

目前关于网壳结构减震的研究,国内外均刚刚起步,同时双层柱面网壳结构在地震作用下的动力响应是不容忽视的。因此,本文从双层柱面网壳的受力特性出发,利用结构动力学原理,对双层柱面网壳结构在替换部分杆件后的减震效果进行了分析。其中包括布置位置、布置数量以及地震波的调幅加速度等方面的研究,通过合理的模拟和计算,表明双层柱面网壳在粘滞阻尼器作用下的减震效果良好,用粘滞阻尼器替换部分杆件是一种有效的减震方法。

Damping Analysis of Double-layer Cylinder Lattice Shell

Nowadys the research about the double-layer cylinder lattice shell is at the beginning.And the earthquake response is very important.In this paper, the damping effects of the double-layer cylinder lattice shell from it's force bear characteristic are analyzed.It's consist of the pace the quantity and the acceleration etc.The calculation result indicates that under the viscous liquid damper,the double-layer cylinder lattice shell has a better effect of damping.It is a effective manner.
