結構動力學:英文版 內容簡介
如今，工程結構的設計，即大跨度橋梁，高層建筑，體育場，機場航站樓和海上平臺，都在其承載能力和自重之間尋求較大的比例，以實現美觀和經濟。然而，這些輕質和柔性結構的類型將導致大的變形和在負載下的過度振動。此外，這些結構可能會遭受一些極端的激勵，例如強風，地震作用，高沖擊力的碰撞以及水波流的沖擊。因此，在滿足設計服務要求時，為了獲得良好的結構性能，研究動態載荷下的結構性能至關重要。結構動力學的基本概念對工程師理解結構振動和采取適當措施很有幫助。本書介紹了“結構動力學”的基本概念和基本原理。盡管這本書著重于結構動力學中的線性問題，但也簡要介紹了一些非線性問題的解決方案。應該注意的是，隨機振動超出了本書的范圍，此處不包括在內。本書的主要內容包括：結構動力學概述，系統運動方程的公式化，SDOF系統動態響應分析，MDOF和連續系統動態響應分析：模式疊加法，近似評估固有頻率和模式形狀，逐步積分方法等本書提出了三項原始的貢獻，即彈性系統動力學中具有固定值的總勢能原理，用于組裝系統矩陣的“正確設置”規則以及在Matlab中的計算機實現方法。此外，本書以簡潔的方式介紹了結構動力學的基本概念，而不是進行詳細的介紹，這對于初學者來說，更有效地理解振動分析的基本概念和方法。
