摘要
应用作者建立的有限段模型.对简支箱梁进行剪滞效应分析,发现变高度简支梁存在负剪力滞.着重阐明了这种负剪滞现象的特性,并对影响负剪力滞的主要因素进行了论述和评价.
A finite segment model has been established and applied to analyse theshear lag effect in simple box girders. It was found that the negative shear lag existed inthe simple box girder with variable depth. The paper mainly described the features of thenegative shear lag phenomenon, discussed the influences of the main factors on the shearlag effect and provided the important information for calculating the negative shear lag forsimple box girders.
