| Abstract: | On the basis of the variational method, a finite difference solution is presented for shear lag effect in Qiantang River Bridge with box section of varying depth. The analytical data obtained has been compared with perspex model tests and theoretical results of finite element method. They are in good agreement. Parts of the analytical results are listed at the end of this paper. |
