elastic critical load meaning in English
弹性监界荷载
Examples
- 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。 - The effect of different sizes of sections , modes and values of residual stresses are studied . through the analysis , the conclusion is arrived at that the universal slenderness ratio should be used to better correlate the stability of box section beams with the member length instead of the out - of - plane slenderness , and the stability coefficient is taken to be 1 . 0 for practical used box girder . then , the elastic critical loads of box section beam - columns are obtained based on the gjelsvik theory , and the relationship between axis force p and moment m is given
最后，运用ansys通用有限元程序的beam189单元，引入初弯曲和残余应力的影响，用考虑几何和材料双重非线性的有限元求解格式求得箱形柱在不同轴力和弯矩比例作用下的弹塑性极限承载力，通过对十几个不同截面尺寸构件在不同长细比下的承载力计算，发现在轴力p远大于弯矩m时，构件将是平面外失稳控制，而当轴力p远小于弯矩m时，构件则以平面内失稳为主。
