钢筋混凝土框架结构延性设计

On Ductility Design for Reinforced Concrete Framework Structure

结合国家规范阐述了钢筋混凝土框架结构延性的重要性，并分析了影响钢筋混凝土框架中框架柱、框架梁以及节点延性性能的诸多因素．结合工程实例从强柱弱梁、强剪弱弯、强节点三个方面体现框架结构延性设计的原则．

In the paper, based on new national standard, the importance of building structure＇s ductility is briefly stated. The factors that influence the ductility of frame column and beam and joint are analyzed. Combined with examples of project, the design principles of reinforced concrete framework structure are discussed in three aspects including ＂strong column weak beam＂ ,＂strong shear weak moment＂ ,＂the strong joint＂.
