longitudinal bracing meaning in Chinese

纵向竖联
纵向支撑

The influence upon the fatigue stress of longitudinal bracing rods due to the transverse vibration of steel bridges
横向振动对钢板梁桥联结杆件疲劳应力的影响
The paper carried out elastic response spectrum analysis on staggered truss frame system , input two strong ground motion records to carry out elastic and plastic time - history analysis . the paper compared the difference of aseismic property between 20 - storeyed composite truss and 20 - storeyed braced composite truss , and concluded that longitudinal brace can not only increase the rigidity but also reduce drift displacement of the first storey . in addition , the paper adopted displacement coefficiency in push - over method to obtain object displacement , and gave the failure modes of the two structures respectively
本文对钢结构交错桁架体系进行了弹性反应谱分析、输入了两条强震记录进行弹性以及弹塑性时程分析，对比了20层混合式和20层纵向带支撑混合式在弹性阶段及弹塑性阶段的抗震性能区别，得出纵向带支撑不但有利于增大纵向的刚度，还可以减小结构底层层间变形的结果；利用pushover的位移系数方法得出了结构的目标位移，并得出了两种结构的破坏模式。
