摘　　要：介绍了预制预应力混凝土结构设计的几点经验 ,这些经验在地震区的预制预应力混凝土建筑结构的应用中获得了成功。本文除了论述刚度、强度和韧性的重要性和它们的相互影响外 ,还特别强调失效 -保险连接节点。这种节点不仅可以传递荷载 ,还能使得整个结构统一、连续和变形协调。本文在如何提高结构刚度以及评判结构设计优劣上给出一些建议。以本文作者 4Discusses the major design considerations necessary in the successful construction of precast, prestressed concrete building structures situated in seismic areas. The importance and interaction of stiffness, strength, toughness and especially, fail-safe connections are emphasized. Such connections are needed not only to transfer loads but to provide continuity and overall monolithic behavior in the entire structure. Suggestions are given on how to increase the stiffness of the structure as well as advice on good and poor design practices. Examples of precast concrete buildings drawn from the author's 40 years design experience are shown and commented upon.
