| Outline of Final Research Achievements |
Authors showed that the octagonal sectional steel and concrete composite column(SC Column) using the cross-shaped steel showed superior earthquake resistant performance and clarified a structure performance rating system.
In this study, we carried out SC column examination body of the section dimensions that were almost size of the original building frame. From the test result, there was not influence of the scale effect to give to the earthquake-resistant performance of this SC column. To design steel beam-to-SCcolumn connection where construction is simple, the stress transmission between steel surface and concrete along column length are necessary, however it is revealed that bond strength between steel surface and concrete is small. In this study, we checked an effect and the design method of the mechanical slip stopper between steel surface and concrete.

| Academic Significance and Societal Importance of the Research Achievements |
地震国家である我が国においては，高い耐震性能を保持する建築構造物を設計することが重要である．さらに，持続可能な建設環境を実現する為には，省人化と省力化が不可欠である．本研究では，十字鉄骨とコンクリートからなる八角形断面の鋼コンクリート合成柱（SC柱）の耐震性能を調べているが，このSC柱と鉄骨梁で構成される建築構造システムは高次元の優れた耐震性能を保持するとともに省人化・省力化の面でも効果的であることを示してきた．しかし，本SC柱は現在の建築基準法の規定のもとでは，合理的な設計ができないのが現状である．今後，この構造システムの開発研究成果を社会に還元していく活動をすべきであると考えている．
