框架节点在地震中的脆性断裂破坏分析

Brittle fracture destroy analysis of the frame joint in earthquake

通过对美国北岭地震和日本阪神地震两个地震破坏实例的概述,分析了钢结构节点脆性断裂的原因,提出了梁柱节点防止地震脆性断裂破坏的措施,从而进一步提高钢结构的抗震可靠度。

According to the review on the destroy examples of the two earthquakes of American Northridge earthquake and Japanese Hanshin- Awaji-daishinsai, the author analyzes the causes of the brittle fracture destroy of the steel structural joints, provides measures of preventing earthquake brittle fracture destroy of the beam and column joints, thus improving the seismic reliability of the steel structure.
