| Abstract: | A tapered beam element model is used to simulate the behaviour of a masonry arch bridge with loading. At each load increment, an iterative method is adopted to predict the displacement. The model is simple and the analysis has shown good convergence characteristics. |

| Keywords: | a tapered beam element effective arch ring iterative method stiffness matrix elastic modulus compressive strength |
