tapered member meaning in English

变截面构形

The discussion on calculation of reinforcing bars in varied cross section by the element stiff matrix of the tapered member
楔形杆单元刚度矩阵计算特殊变载面构件配筋的探讨
Due to their structural economy , tapered members are more and more widely used in portal frames . however , the stress distribution and in - plane inelastic stability of tapered members are not yet fully documented
本文对门式刚架结构中常用到的楔形变截面构件进行了应力分析与弹塑性稳定的研究。
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。
