摘要:
为了限制动荷载作用下梁端的位移,经常要在梁端安装阻尼器,与伸缩缝在结构上形成并联装置。当桥面突然发生大规模的刹车,或在突加的地震、风荷载等荷载的冲击作用下,阻尼器是否会对伸缩缝起到保护作用就成为一个令人关心的问题。由一般多自由度体系动力方程出发,通过矩阵变换得到结构局部关于阻尼器单自由度方程。基于此单自由度方程,对阻尼器在结构中具有局部减震效果提出了理论上的论证,在此基础上就阻尼器在各种冲击荷载作用下对伸缩缝的保护作用进行了探讨。
Abstract:
Fluid viscous damper is usually selected to be equipped at the ends of beam to restrict their displacements.Under this condition,fluid viscous dampers and expansion joint are usually parallel in structure.The question is whether the damper have the protecting function for expansion joint under the impact force caused by earthquake,wind and vehicle etc.From multi-degree-of-fredom equation,a local single-degree-of-freedom equation of damper is obtained by matrix transform,and on the basis of it,the effects of decreasing local vibration is put forward in theory.Subsequently,The protecting function for expansion joints of damper under the impact forces is investigated.
