lateral symmetry meaning in Chinese
横向对称
两侧对称
Examples
- The strip theory can meet the demand of shipbuilding engineering . but the common method can only use on ships with lateral symmetry which is in the state of zero trim
当今广泛采用的切片法满足了工程上所需要的精度要求，但一般都只能适用于正浮状态具有横向对称性的船舶。 - Modeling the general solid web continuous box girder and opening - in - web ( open web ) continuous box girder by ansys finite element modeling tool , node stress of governing section and corresponding shear lag values are analyzed . the solution is validated by comparing with variational results and modeling test values . based on the model , the section shear lag induced by dead load , prestress tendons and car loads under the most unfavorable condition and lateral symmetry are also approached . the influence of shear lag effect in double - level continuous box girder is considered with opening - in - web and the web location . the analysis indicates that double - level - load arouses less shear lag effect than one - level - load . when self - weight and prestressed tendons act on together , the shear lag effect on box girder take on a evidently change
基于所建立的有限元模型，本文分别对实腹和腹板开孔两种箱梁在恒载、车载、预应力荷载作用时，各主要截面的剪力滞效应进行分析，通过施加纵向最不利的和横向对称的车辆荷载，研究实腹连续箱梁和空腹连续箱梁在承受双层荷载和单层荷载时引起的剪力滞效应，并考虑腹板开孔及开孔位置对于连续箱梁剪力滞效应的影响。分析表明，双层车载对于箱梁引起的剪力滞系数比单层车载的影响要小，对于箱梁中存在引起的剪力滞后现象有一定的改善作用。
