trusses

The aim of this thesis is to develop a method to optimize trusses in minimum weight and number of cross-section types used.
本论文之目标在发展一桁架最佳化的方法，来最少化桁架重量及其使用断面型式的数量。
However, once assembled trusses take up a greater amount of space and, in more complex structures, can serve as a distraction to drivers.
然而，一旦组装桁架采取了一个更大的空间量，并在更复杂的结构，可以充当司机分心。
The components of a suspension bridge are: flexible cables, towers, anchorages, suspenders, deck and stiffening trusses.
悬索桥有下列构件：柔性索缆、索塔、锚固件、吊杆、桥面、加劲桁架。
To save weight, they even lost their teeth. Bones became hollow, strengthened with a honeycomb of trusses.
为了减少体重，它们甚至不惜牺牲牙齿，骨骼也变成了蜂窝一样中空而坚固的结构。
The numerical examples in this paper show that the method can be used to analysis large deflection of space trusses.
计算表明本文方法可以有效用于空间桁架结构大位移问题分析。
The adoption of the method can cause large damaged trusses to run well and satisfy production requirements.
采用本发明方法后可使大型受损桁架运行良好，满足生产要求。
The total cost is minimized under predetermined reliability of trusses.
在满足结构总可靠度的情况下，使结构造价最低。
The comparing tests show that: the concrete-filled in chord trusses have the higher bearing capacity of the overall truss and joints.
研究表明：内填混凝土桁架比空钢管桁架具有更高的整体承载力和节点承载力。
As the consequence, the special joints are tensed by the gravity of the single trusses below.
因此特殊节点受到下方桁架的自重造成的竖向拉力。
The calculating results showed the stress ratio and displacements of the above two type trusses were satisfied with design codes.
计算结果表明，两种桁架体系的应力水平和位移情况均满足设计要求。
