1)  Open cross-section
开口横截面
2)  open section
开口截面
1.
The torsional stiffness of cable-stayed bridge with open section is very low.
开口截面斜拉桥的自由扭转刚度较低,其翘曲刚度和自由扭转刚度相比不可忽略,采用模型的不同将严重影响扭弯频率比,而扭弯频率比对颤振起至关重要的影响,故扭转刚度的正确计算是抗风分析的关键。
3)  steel-concrete composite beams with open sections
开口截面组合梁
4)  open cross section
开口截面主梁
1.
The triple-girder model can consider the warping constant of deck and can calculate the warping frequency of the structure of cable-stayed bridges,which can be applied to an mechanical model of deck with an open cross section.
三主梁模型考虑截面的翘曲刚度,能准确计算结构的扭转频率,可用于模拟斜拉桥开口截面主梁。
5)  thin-walled beam with open section
开口薄壁截面
1.
Simple calculation of the coordinates of the bending center of the thin-walled beam with open section;
开口薄壁截面梁的弯心坐标的简便计算
2.
This paper examines the shearing flow of any thin-walled beam with open section and the calculation of the coordinates of bending center.
研究任意开口薄壁截面杆的剪力流和弯曲中心坐标的计算问题,利用合力矩定理导出计算公式,给出算例。
