●本書の特徴

耐震設計の基礎学理をなす建築・土木分野における構造動力学の体系が,完備された体裁の下に整然と説かれる。時間領域と周波数領域とにおける現象把握のありよう,空間場における系特性の記述形式の諸相といった一般性のあるパラダイム構成を明示して,構造物振動に固有な題材をとりあげた特論を付け加えている。線形論に徹する性格が強く押し出され,系の塑性履歴化に関わった非線形問題へはあえて立ち入らない。ただし,幾何非線形性は対象となる。また,確定関数の世界にとどまって,確率過程としての不規則振動論にはほとんど触れない。それらは本書の限界というよりも,拡散を避けて焦点が十分に絞られる点でむしろ特徴といえよう。動力学の展開に必須の数式表現術や減衰系の振動論,さらに地震動の作用を受ける建築物に即した振動の諸形態などを詳述する。専門技術者・研究者を対象とした生涯学習用の教本ないしは学問体系の秩序化を目指した学術研究書であると共に,基本事項が集約された公式集的な側面をも併せ持つ学術研究書。
