摘要
应用考虑剪滞效应的有限段模型，对一般变截面箱梁的负剪力滞进行分析．探讨了变高度简支箱梁、悬臂箱梁的负剪力滞受梁高比、宽跨比以及荷载型式等因素变化的影响．获得了变截面箱梁负剪力滞的一般规律和初步结论，为负剪力滞计算提供了重要参考．
A finite segment model has been established and applied to analyse the negative shear lag in box girder with varying depth.This paper discusses the influence of the main factors,including the girder height ratio,the width to length ratio and any loading arrangement,on the negative shear lag in variable depth simple—,cantilever—,and continuous box girders.The features of the negative shear lag phenomena are described and some important conclusions are drawn about calculating the negative shear lag for box girders with varying depth.
