stressing bar meaning in English

预应力铜筋

Secondly , through the examination and observation of the structural model of the cast - in - place pre - stressed compound floor slab system , under the normal usage load , the normal usage limit - state and the failing load , we have validated the space working - feature of the structural model under variable loads , including the rigidity , the crack , failing - state , failing load and the stress variation of the pre - stressed bar , and so on
其次，通过对该体系的结构模型在正常使用荷载、正常使用极限状态和破坏状态下的试验研究，验证了现浇预应力复合楼盖体系模型结构在各种荷载作用下的空间工作性能，包括刚度、裂缝、破坏形态、极限承载力及预应力筋的应力变化状态等。
A predigested car model and a reasonable bridge model were presented after the bridge structures and the colliding characters were analyzed . the stress and the displacement of the concrete , bar , pre - stress bar changing with time were presented . the stress of the whole bridge at the time of the contact and the deformation of the whole bridge at the end of the contact are obtained
采用美国ansys公司的有限元软件ansys ls - dyna对碰撞过程进行数值模拟分析，得到了撞击点附近混凝土、普通钢筋以及预应力钢筋的应力及位移随时间的变化规律，同时得到了全桥在碰撞后瞬间的应力分布规律和碰撞结束前全桥的变形规律。
