1 引言
预应力混凝土(Prestressed Concrete)在大多数钢筋混凝土设计教材中只占很少的篇幅, 通常是一章, 最多也就二三十页. 而今天得到的这本教材是专门写预应力混凝土的, <Prestressed Concrete Analysis and Design: Fundamentals>(47MB), 由密歇根大学(University of Michigan)土木工程系Antoine E. Naaman教授执笔, 更令人叹为观止的是这本书大约1100页. 下面简要介绍一下这本书.
2 预应力混凝土分析与设计
"Prestressed Concrete Analysis and Design: Fundamentals"(预应力混凝土分析与设计: 基本原理) 第二版, 2004年出版. 预应力混凝土是世界上最可靠、最耐用、最广泛使用的建筑材料之一。它为建筑业、预制制造业和整个水泥行业做出了重要贡献。它带来了大量的结构应用,包括建筑物、桥梁、核电容器、电视塔和海上钻井平台。Naaman教授的这本书是为土木工程系高年级学生、职业工程师和研究人员编写的。它是一本讲解透彻的教材,一个全面的信息来源以及一个基本的参考。它强调对预应力混凝土结构进行分析和设计的基本概念,为用户提供处理日常设计问题的基本知识和工具,同时鼓励必要的批判性思维,从而自信地处理更复杂的问题。
