抗震加固的粘弹性阻尼减振(震)新技术
|
摘要
粘弹性阻尼减振(震)技术是结构减振(震)控制中最为适用的技术之一,将粘弹性阻尼器加设到结构柱间支撑等可变形部位,可耗散结构的振动能量,从而有效减小结构的地震反应。介绍用于建筑结构中的粘弹性阻尼器类型、力学模型以及加入粘弹性阻尼器结构的分析设计方法。为进一步加快粘弹性阻尼器在实际工程中的应用,简要介绍了加入粘弹性阻尼器结构的试验研究和工程应用概况。
As one of the most adaptive structural damping technique,Viscoelastic damper(VED) technique is systemically introduced in this paper.The vibration energy will be dissipated and the earthquake responses of structures will be reduced effectively when VED are installed in the deformable places of structures,such as braces between columns.The kinds,mechanical models of VED used in building structures and analytical design methods of the VED structures are described.In order to further speed up the practical application of VED,some experimental studies of VED structures and engineering applications are exhibited briefly.
