摘要
铆接连接今天在桥梁工程中已不再采用 ,但许多建于铆接时代的桁架桥仍在运营 ,它们的承载安全问题已引起人们的关注。提出构件强壮度的概念 ,并运用断裂力学方法验算铆接桁架桥的承载安全 。
Riveted structures have never been applied nowadays in bridge engineering.Yet many riveted truss bridges built in the riveted times are in service.People have already paid attention to the load carrying safety of these bridges.In this paper the concept “robust” is proposed, and fracture mechanics is applied to assess the load carrying safety of riveted truss bridges.The structural components to be strengthened are indicated.
