Selecting the type of structural members in the preliminary design of space structures based on neural networks 网架结构初步设计中杆件类型选择的神经网络方法
The influence upon the fatigue stress of longitudinal bracing rods due to the transverse vibration of steel bridges 横向振动对钢板梁桥联结杆件疲劳应力的影响
Tension structure is one kind of large - span space structure , which combines cable with truss by some way 张拉整体结构是将柔性索与刚性的杆件组合在一起的一种大跨度空间结构。
Hollow structural sections ( hss ) are commonly used as bracing members insteel - framed buildings or as web members in roof trusses 钢管截面通常用作支撑钢框架中的支撑构件或屋顶桁架中的腹杆杆件。
As a result , it is suggested that distortion should be taken into account to calculate the thin - walled bar with restrained torsion 因此建议，对薄壁杆件作约束扭转分析时一定要考虑截面畸变的影响。
The method is adept to the welded machine which is consist of multiple kinds of steels and the steels are angled with any condition 该方法适用于由多种型钢混合组成，且型钢杆件间成任意角度的焊接机架。
Vgwi hav vny good the td weigh ndos , and no wt moments or tomp can be nd at the joints . moieover they can be deded to be cowe 变几何桁架机构是包含一些可伸缩杆件的静定桁架，这些可伸缩杆件可以改变机构的构形。
But stress and contexture of space structure are very complex . it is difficult that planners estimate practical internal force 但是由于大跨结构的受力和构造均较复杂，设计人员很难准确估计各杆件和节点的实际内力值。
Furthermore , the thesis introduces the design of the members and joints in space grid structure , and gives the flowcharts of program 本文还介绍了空间网格结构的杆件和节点的设计，并给出了杆件、节点设计的计算流程框图。
Overall auto sales for the first half rose 9 . 35 percent year - on - year to 2 . 79 million units and auto output was up 5 . 15 percent at 2 . 82 million units 公司将形成轿车前后桥总成模块套，商用车悬挂杆件套，转向杆件套的生产能力。
