延性理论在结构概念设计中的作用与体现

结构设计中不仅必须重视属于结构外部因素的“力”，而且要牢牢地掌握及控制好属于结构内部因素的“延性”。本文通过举例，阐述并分析延性理论在整体结构及单一构件设计中的体现，从中折射出了延性理论在结构设计中所起的重要作用。

Role and Reflects of Ductility Theory in Structure Conceptual Design

Structure design not only must pay attention to the ＂force＂ of structure external factors, but also to firmly grasp and control the ＂ductility＂ belongs to structure internal factors. This paper through examples, expounds and analyses the ductilcity theory reflected in the design of overall structure and single component, reflecting the important role played by the ductility theory in the design of structure.
