| 摘 要： | 文章推导出一种分析箱梁剪力滞效应的广义应力杂交有限条板壳单元,把组成箱梁的各个板块看成一个大单元,利用有限条方法来推导其平面内的单元刚度矩阵。研究结果表明,这种单元用于计算箱梁的应力分析具有很好的精度和效率,适合于分析箱梁的剪滞效应,它兼有应力杂交元和有限条法的优点。

| Abstract: | In this paper,a generalized hybrid finite strip element is deduded for analyzing the shear lag effect in box girders.It has the advantage of both the generalized finite strip method and the hybrid stress element.A typical example demonstrates that the proposed element has higher accuracy and efficiency,and the method is suitable for analysis of shear lag effect in box girders. |
