  • Effects of span length of beam on vertical response of seismically isolated building considering soil-structure-interaction effects  [in Japanese]

    KINOSHITA Takahiro , SATO Toshiaki , NAGANO Masayuki , KITAMURA Haruyuki

    本論文では、地盤との動的相互作用の影響が大きい免震構造の上下応答に関し、上部構造の梁スパン長さの差異が振動特性に与える影響を検討した。梁スパン長さとして5ケースを想定したモデルを設定し、その変化が上部構造およびアイソレータの応答に与える影響を把握した。スパンが長いほど、梁振動が上下応答に与える影響は大きく、アイソレータの軸力を増大させる傾向を示した。最後に、各ケースに対し、相互作用の影響を基礎固定 …

  • Possibility of Myxomycetes as a Bio-indicator in Urban Green  [in Japanese]

    IWATA Tatsuki , SUZUKI Masakazu

    近年都市緑地において環境指標に生物を利用する際、生物の移動分散能力の制限などから、狭く孤立した緑地で利用できる環境指標生物が少ないという問題がある。また、南北に長い国土において、普遍的に分布する生物種も少ない。そこで、本研究では、変形菌(真性粘菌)が都市緑地において環境指標生物として利用できないかを、東京都の緑地を事例として検証することを目的とする。結果、変形菌が林床生態系において、分解者を捕食す …
