箱形截面梁具有较大的抗弯刚度和抗扭刚度、受力性能好、跨越能力大、桥上视野开阔等优点，是桥梁设计中常用的结构形式，在受恒载或对称活荷载作用下挠曲时，由于翼板的剪切变形致使其弯曲应力沿梁宽度方向呈现不均匀分布状态,此现象称为“剪力滞效应”。忽略剪力滞的影响，就会低估结构实际产生的最大曲线应力，从而造成结构不安全和设计的不合理，易出现重大的事故。
本文通过空间有限元法对两跨曲线连续钢箱梁剪力滞效应问题展开研究。根据钢箱梁的具体受力特点，采用空间有限元模型分析钢箱梁分别在集中荷载和均布荷载下的翼板应力分布和剪力滞效应问题，揭示了钢箱梁剪力滞的一般规律，为正确认识钢箱梁的抗弯力学特性奠定了坚实的理论基础，同时也为促进我国广泛研究和修建同类箱形桥梁在理论上提供了支持。

The curve continual steel box Liang shearing force stagnates the effect finite element analysis
box section Liang has the big flexural rigidity and torsional stiffness, the stress performance good, spanning ability big, on the bridge the field of vision open and so on the merits, is in the bridge design the commonly used structural style, when receives under the dead load or the symmetrical live load function winding, because the lifting surface detrusion causes its bending stress to present the non-uniform distribution condition along the Liang width direction, this phenomenon is called “the shearing force to stagnate the effect”.The neglect shearing force stagnates the influence, can underestimate the structure produces actually biggest curve stress, thus creates the structure not security and the design is unreasonable, easy to appear the significant accident.
This article stagnates the effect question through the spatial finite element method to two cross curve conti
