| 摘 要： | 通过对不同宽跨比的简支薄壁宽箱梁建立空间板单元模型,对比在恒载作用下跨中剪力滞效应的计算结果,讨论B/L=0.5作为宽窄箱梁工程界定的可靠性.进一步研究梁高对宽箱梁横向受力的影响,进而提出以剪滞系数控制宽窄箱梁工程界定的依据,希望能为工程设计提供参考.

| Abstract: | Based on the different width span ratio of simply supported thin-walled box girder the space plate element model is established, and compared with the calculation results under the action of dead load across the shear lag effect, the B/L=0. 5 as the width of box girder to define reliability is discussed. Furthermore the engineering definite basis using shear lag coefficient to control wide-narrow box girder is put forward. Hopefully it can provide reference for engineering design. |
