摘要
分析了弹塑体在动荷载下的应力；用大变形有限元法，分析桥梁结构中无缝式伸缩缝弹塑体在拉伸作用下的结构应力，总结了弹塑体最大拉伸应力与结构的宽深比、泊松比和有效模量之间的关系，并给出了它们的回归计算公式。
The article analyzes the stress of lastics under live load and the structural stress of alete shrinkage joint lastics under tension effect in bridge structure by using big deformation finite element method, summarizes the relationship among maximum tension stress, breadth depth ratio and Poisson＇s ratio of structure, and effective modulus, and introduces their return calculation formula.
