摘　　要：薄壁多室箱梁因自身优异结构性能和良好截面形式,以及便于现代化施工和满足大交通流量等优势在桥梁建设中应用甚广.文中介绍了线性插值函数以及如何用线性插值函数模拟多室箱梁横截面的纵向翘曲位移,拓展了分析多室箱梁的剪力滞后问题的思路.Thin-walled multi chamber box girder is widely used in bridge construction because of its excellent structural performance, good cross-section form, convenient for modern construction and large traffic flow. This paper introduces the linear interpolation function and how to simulate the longitudinal warping displacement of the cross section of the multi chamber box girder with the linear interpolation function.

关 键 词：多室箱梁 线性插值函数 剪力滞后分析
