PEDESTRIAN-INDUCED VIBRATION IN FRP TRUSS FOOTBRIDGES
Doboku Gakkai Ronbunshu, 2003 本論文では, スパン30mクラスのFRP歩道橋の振動特性を明らかにすることを目的として, まず, ガラス繊維補強FRP形材を用いて断面算定を行い, その自由振動解析から, 1次の非減衰自由振動モードは水平横方向変形の卓越するモードで, その振動数が歩行との共振周波数と近接していることを論じている. 次に, 単独歩行者モデルを用いた時刻歴応答解析を実施し, 水平横方向の固有振動数に近い歩行振動数の歩行外力を入力した場合, 水平横方向に大きな応答を生ずることを明らかにした. 対応する振動モードでの軸歪エネルギーが卓越する部材のみをカーボン繊維形材にすることで, 歩行による振動を小さく抑えることができることも示している.
