內容簡介
本書屬普通高等教育“十五”國家級規劃教材,是按照教育部力學課程教學指導委員會擬定的《結構力學課程教學基本要求》編寫的想膠酷故,旨在適應當代工程概念分析及概念設計的理念和需要。本書的特點是:以結構力學的基本概念、基本原理及其科學運用為主線;以認知規律為出發點;以工程實踐為背景;以素質與能力的提高為目標。本書是同濟大學有關教師在長期從事結構力學教學和科研以及工程實踐的基礎上寫成的妹格,體現了作者有關“概念結構力學”的基本思想。
全書分上、下兩冊。上冊共7章,主要內容包括靜定結構部分、力法和位移法。下冊共5章,主要內容包括矩陣位移法、超靜定結構的實用計算方法與概念分析、結構動力學、結構的穩定性和極限騙墓棕荷載,並附有平面剛架靜力分析的源程式及說明。
本書概念清晰、內容簡明、深入淺出和聯繫實際。在介紹解題方法的同時更注重“就事論道”和“由技入道”,力求使讀者深刻領會客觀規律並掌握事物的本質。另外,研製了CAI教學軟體光碟,通過動畫生動地展現樂套雅教學內容並積極引發課堂討論,可供教師方便地實現多媒體臘煮槳祝教學。
本書可作為高等學校土木、交通、水利、機械和力學等各專業的結構力學教材,也可作為相關專業工程技術人員等的參考書。
