異種構造部材で構成される合成構造の設計法に関する研究 (その1)

Abstract

The object of this study is to make clear experimentally and theoretically the stresstransferring mechanism of exterior joints in mixed structures. Four specimens are testedunder reversed loading. The column is composed of steel and reinforced concrete and thebeam is made of steel. Experimental variable chosen is the ratio of the flexural strengthof steel element contained within composite column to the flexural strength of compositecolumn. Main discussion is concentrated on the failure mechanism, hysteretic characteristicsand the ultimate strength. On the basis of test results, the analytical model is suggestedand the ultimate strength formula based on the method of superposition shows a goodagreement with the experimental results.
