vertical curvature meaning in Chinese

竖向曲度

Then , a step - by - step increase of vertical curvature is applied to the hull girder assuming that the plane cross section remains plane . at each incremental step , the stress of the cross section is evaluated using the average stress - strain curves of the elements as well as the incremental bending moment due to the curvature increment . performing sample calculations on existing girder models tests under pure bending , the rationality of the proposed method was examined
假设船体横向框架材足够强，因而板架的整体破坏不会发生；基于梁?柱理论、理想弹塑性假设、平面假设，建立了拉伸和压缩加筋板单元的平均应力?应变关系曲线，应用船体结构总纵极限强度的简化逐步破坏分析方法计算船体总纵极限弯矩，并据此开发了计算程序sus 。
