摘要
应用有限单元法，将空间螺旋线薄壁箱形梁离散为平面壳元的组合，求得直线、平面曲线和空间螺旋线薄壁箱形梁的位移和应力场，讨论其中存在的剪滞效应，并分析曲率半径和空间坡度对剪滞的影响．
By use of the finitc element method, the stress yields for stheght plane curved and spase hclical thin-walled box girders when they are separated as an assemblies of the plane shell elements are discussed The shear lag Phenomenon and the effect on shear lag with respect to curvature radus as well as spee slope are also inveshgatcd.
