纵向弯曲 meaning in Chinese
ausknicken
buckling
collapse
kinking
lateral flexure
longitudinal bending
longitudinal bowing
Examples
- Reduced buckling length
折合纵向弯曲长度 - However , there is shear lag effect in thin - walled box girder when thin - walled box girder is bent in the longitudinal direction
然而，箱形薄壁梁在纵向弯曲时，存在剪力滞效应。 - The compact fiber core layer make the sections very tough and firm , the lengthways bend intensity and compact intensity is higher than common rolled steel
致密的纤维芯层使得型材非常坚韧牢固，其纵向弯曲强和冲击强度的绝对值已高于普通钢材。 - In conventional design methods , the interactions between superstructures and foundations are not considered , and the constraint of superstructure towards foundations ( i . e . the contribution of the rigidity of superstructure ) are neglected , which lead to over - large bending moments and buckling of foundations and conservative foundation design
常规设计方法没有考虑上部结构与地基基础的共同作用，忽略上部结构对基础的约束(即上部结构刚度的贡献)作用，计算结果导致基础弯矩和纵向弯曲过大，基础设计偏于保守。 - In the hogging condition , double bottom and the side shell remain the ultimate bucking strength , deck and upperwing tank remain the yield stress , and the other parts keep elasticity . then the key to calculate the ultimate strength of ship hull girders is to ascertain the ultimate bucking strength of the stiffened panels . in this regard , the developed formulation is designed to be more sophisticated than previous simplified theoretical method for calculating the ultimate strength of stiffened panels under combined in - plane bending and lateral pressure . fabricatio n - related initial imperfections ( initial deflections and residual stresses ) are included in the panel ultimate strength calculation as parameters of influence . all possible collapse modes involed in collapse of stiffened panels , including overall buckling collapse , column or beam - column type collapse , tripping of stiffeners and local bukling of stiffened web are considered
确定了船体梁整体破坏时的剖面应力分布之后，关键在于确定板架的极限屈曲强度。本文充分考虑了在纵向弯曲、横向压力作用下加筋板可能发生的几种破坏模式，即板架的整体屈曲破坏、梁柱形式的破坏、筋的侧倾、腹板的屈曲并同时考虑了初始焊接残余应力、初挠度的影响，使其更精确的计算加筋板的屈曲强度。对于加筋板中加强筋腹板的局部屈曲，采用解析法推导出筋的腹板的挠度方程及其边界条件，求解相应的方程，从而计算出腹板的局部屈曲应力。
