catenary action

基本解释

This paper investigates the large deflection behaviour of steel beams under fire conditions taking into consideration the effect of catenary action provided by the surrounding structures.
为了研究高温下钢梁的大变形性能，本文使用ABAQUS有限元程序建立了分析模型。
On the principle that the shape of the main cable between hangers is catenary, the iteration method of calculating the coordinates of the spatial main cable under the action of hangers was deduced.
基于空间分析模型，研究了自锚式悬索桥空间主缆线形的精确计算方法，根据主缆在吊杆之间的各索段在自重作用下呈悬链线，推导并研究了空间主缆在吊杆力作用下坐标的迭代计算方法。

链式反应
Specifically,this investigation concentrated on developing connection methods to enable catenary action in the connected beam to be more fully developed.
对连接方式进行改进,以期使连接梁的链式反应能更好发展。
悬链线效应
At the same time, the catenary action is analysed due to increase of the girder’s deflection. The fire-resistant limit is influenced by the catenary action.
同时分析由于梁挠度的增长而产生的悬链线效应对整体抗火极限的影响。
