| 4. | 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。 |
| 5. | By an example , the warping theory of the thin - walled beam is compared with and distinguished from gbt , while the contribution and the defect of the former is presented 本文通过算例对广义梁理论和薄壁杆件翘曲理论进行了比较研究,并指出了后者的贡献和局限性。 |

| 8. | Firstly , with uniaxial symmetrical rectangle cross section , the warping displacement function and tangential displacement function under anti - symmetrical load are supposed . then taking shear deformation into account and with potential principle , the governing differential equation for distortion angle subjected to uniformly distributed distortion load is established 首先,以单轴对称矩形截面薄壁杆件为研究对象,假设其在反对称荷载作用下翘曲位移和切向位移的分布函数,考虑剪切变形的影响,利用最小势能原理建立单位均布畸变荷载作用下的畸变角微分方程。 |
| 9. | Because numerous mega - columns and mega - beams of mega - frame are thin - walled beam , hence the torsion can " t be neglected in structural calculation , and so in the calculation of structural overall stability , the coupling of bend and torsion can " t be neglected . the second is the thin - walled beam with opening section element which be considered effect of axis force and the coupling of bend and torsion 由于巨型结构中许多巨型柱和巨型梁为薄壁杆件,所以在结构计算中就不能忽略扭转,同样在结构的整体稳定性计算方面就必须考虑弯曲与扭转的耦合,所以作者推导了开口薄壁杆件在考虑轴力效应、弯曲与扭转耦合时的单元。 |
| 10. | It is concluded that a certain amount of diaphragm will reduce the distortion effect greatly , but on the other hand , even with a fairly great density of diaphragm , such as the ratio of diaphragm span to the greatest dimension of the cross section is as small as 1 . 25 , the distortion effect ca n ' t be neglected compared with the effect of rigid torsion 通过研究得到初步结论:设置一定数量的横隔板可以大幅度地减小薄壁杆件的畸变效应;另一方面,尽管横隔板设置到比较大的密度(横隔板间距与截面最大尺寸之比为1 . 25 ) ,与刚性扭转效应相比,畸变效应仍不能忽略。 |
