This paper clarify the elasto-plastic behavior of flange, reinforced by cover plates, taking account of web plate of H-shaped steel member, subjected to the concentrated normal force to its flange. In this study, we have done experiments using full-sized member and F. E. M. analysis taking advantage of test results. We proposed the simplified manner to estimate the local strength and stiffness of flange portion in normal direction combining the web's behavior. The calculated values according to our proposed manner showed a good agreement with the test results in good accuracy.
