钢板梁
Examples
- The authors describe the modelling of a railway steel truss bridge with long - span in order to analyse the detailed distribution of stress for members and nodal plates in main truss , the detailed deformation and stress distribution due to frame effect on transversal bracing plane in truss bridge , and the detailed distribution of stress in important parts of the steel plate girder bridge with initially transversal deformation by using sseb in this article
本文建立大跨铁路钢桁梁桥和钢板梁桥全桥结构仿真分析数学模型，说明了钢桁梁桥杆件和节点板详细应力分布、平面框架详细变形与应力分布和有变形缺陷钢板梁桥重要部位应力的仿真分析结果等问题。 - Based on qualitative analysis and comparison of several options for suppressing transverse vibration on deck type steel plate girder of railway bridge , conclusions are made as follows : with static reinforcing , the vibration amplitude can be suppressed to some extent , but quasi - resonance of the bridge can not be avoided , moreover , the construction is inconvenient and costly . with option of two bridge connection , the effectiveness of vibration suppression is clear ( the damping ratio approaches 50 % ) and it is fairly economic and easy , however , the quasi - resonance of the bridge can not be avoided either . with dynamic option ( mtmd option ) , the quasi - resonance of the bridge can be effectively avoided ( the damping ratio is up to 51 . 38 % as tested in field ) , moreover , the construction cost is low , and the construction is simply and convenient
通过对目前抑制铁路上承式钢板梁桥横向振动的几种方案进行定性的分析和比较，认为：静力加固方案可以使桥梁振幅有所减小，但不能避免准共振现象的发生，而且工程造价较高，施工也不方便；两桥连接方案减振效果明显(减振率近50 % ) ，比较经济也比较方便，但同样不能避免准共振现象的发生；动力减振方案( mtmd抑振方案)可以有效的抑制桥梁的准共振现象(现场试验中减振率达51 . 83 % ) ，而且工程造价较低，施工简单、方便。
