Flexural crack width measured in the tests is compared with computed flexural crack width and well simulated. However, some cracks were not measured due to concrete spalling at 1.0% roof drift. Thus, flexural crack width was over estimated. On the other hand, in this study, elongation on tensile fiber corresponds to flexural crack width. Therefore, it is compared to computed flexural crack width. Accumulated elongation is well simulated and total elongation is simulated within ±30% error. It shows this method well predict flexural crack width except effect of concrete spalling. Maximum flexural crack width is simulated approximately within ±30% error as well. Flexural crack length is also simulated with the method based on Bernoulli-Euler theory and compared on crack length ratio. Cracks progress horizontally such as pure flexural crack is well simulated. However, cracks progress obliquely such as flexure shear crack is not well simulated due to the deference of propagation manner between test and numerical simulation.
