This paper addresses an experimental behavior of stub columns and flexural members made of 570MPa steel pipes for aseismatic building structures as a fundamental study to enhance the applicability of high strength steel. In this study, mechanical properties(chemical compositions, mechanical test, charphy impact test, welding performance etc) and structural performance of 570MPa steel pipes in accordance with their width-thickness ratio are quantitatively estimated. A total seven specimens(stub column:3ea, flexural specimen:4ea) are tested. The main results show that : 1) maximum strength of stub columns and bending specimens are shown 1.02～1.21, 1.23～1.38 times of calculated values. 2) the final modes of stub column specimens and bending specimens are obtained by the local buckling.
