材料の組み合わせを考慮した充〓被覆型鋼管コンクリート柱の耐力と変形性能

Concrete filled steel tubular columns are frequently used for high-rise residential buildings in Japan. In this paper, the ultimate strengths and plastic deformation capacities of these columns with covering concrete were experimentally investigated for various combinations of materials, such as ordinary strength and high strength concrete. As the results, it is verified that the ultimate strengths of these columns can be evaluated with the generalized superposed strength theorem, and their plastic deformation capacities are satisfactory against severe earthquakes.
