对我国在预应力混凝土箱梁结构剪力滞效应方面的主要研究方法进行了评述 ,通过实例比较各方法的计算精度和适用范围 ,并提出了有待于进一步研究解决的若干问题及其研究的努力方向。这对于加速箱梁剪力滞理论的深入研究 ,为大跨、新型桥梁结构的性能评价提供正确的计算模型有一定的参考价值。
The main research methods of shear lag effect of prestressed concrete box girder structures are reviewed in this paper. The calculation precision and application range of each method are compared through examples, and some problems to be further studied and the efforts of the research are put forward direction. This is of great value for accelerating the theory of shear lag of box girders and providing the correct calculation model for the performance evaluation of long-span and new-type bridge structures.
