arch rib

基本解释

D FEM analysis model is adopted for the stability analysis in construction including hoisting and closing single steel tubular arch rib and service stages respectively.
采用空间杆系计算模型对包括单根钢管拱肋吊装合龙在内的施工和运营阶段进行稳定性分析。
In the practical project, arch rib and girder of the arch bridge are always bluff sections, such as rectangle and trapezoid etc, which occur vortex-induced vibration easy on the action of wind.
在实际工程中，拱桥结构的拱肋以及主梁截面一般都采用比较钝的截面形式如矩形、梯形等，这样在风荷载的作用下很容易产生涡激振动。
The visual calculation system in the swing-bridge construction is an arch rib stability analyzing calculation software, which aims at the light swing-bridge in the construction process.
转体桥施工中稳定性可视化计算系统是针对轻型化转体桥在施工过程中，拱肋稳定性分析的计算软件。
