 note = {高架橋に沿って伝播する波動モードを数値解析により調べた. 当該構造物は無限周期構造により理想化し, はりモデルで離散化した. 減衰せず無限遠まで伝播して行く波動モードの解析において, Floquet原理を適用することで具体的解法を構成した.この場合,無限周期系における波動問題は, 周期構造を構成している最小単位(ユニットセル)の離散化により解析可能となる. 具体例を対象に伝播モードの分散曲線を求め, 発生し得るモードの種類とバンド特性について調べた., Wave propagation is analyzed for a periodic viaduct. By virtue of the Floquet's principle the dynamic problem can be reduced to the one in a unit cell representing the periodicity. This formulation leads to an eigenvalue problem associated with the Floquet wave number (propagation constant) and the circular frequency. The group velocity dispersion curves are drawn by solving the eigenfrequencies with scanning the wave number interval. It is found that the propagation modes can be classified into two groups. One is characterized by the deflection of girder. The other is dominated by the bending of columns. The influences of numerical modeling on the dynamic properties are also investigated.},
