prismatic member meaning in English
等截面杆
Examples
- Shear stresses and shear strains in prismatic members may be caused by either torsional moments, or by shear forces associated with flexure .
在等截面杆件中，剪应力和剪应变可以由扭矩引起，或者由变曲相关的剪力引起。 - Firstly , the shear and normal stresses of tapered members under the transverse load or axial load are analysed , and the stresses formulas are obtained which are different from those of the prismatic ones . secondly , research is done on the in - plane inelastic stability of tapered members under axial loads about strong axis and weak axis . a new design method is suggested in which the tapered member is equivalent to the prismatic member with the cross - section at the larger end of the tapered member
同时由分析可知，目前采用的将变截面压杆按照弹性极限荷载等效的原则等效成以小端截面为准的等截面压杆的设计方法，在弹塑性阶段低估了压杆的承载力，即弹性等效的压杆在弹塑性阶段并不等效，实际变截面压杆的承载力比等效的等截面压杆的承载力要高。 - In this part , it is also found that the equivalent prismatic column , which is obtained based on the equal elastic critical load as the non - prismatic member , is not actually equivalent to the tapered column in inelastic stability , and the latter has higher load carrying capacity . finally , the behavior of tapered beam - column acted by combined axial load and transverse load has been investigated . a bending - thrust interaction curve is established which is similar to the ones for the design of prismatic members
三是研究了楔形变截面悬臂构件在大端固定，小端同时承受横向及轴向荷载共同作用下的强度和弯矩平面内的稳定，同时参考等截面构件的设计公式，得到了用大端截面来表示的轴力p与弯矩m的之间的相关关系。
