摘要
桥梁的体系可靠度与基本构件的可靠度是不同的,二者之间的差异随桥梁跨径、主梁间距和主梁数量而变化。而且,作为整个体系,失效模式有很多,若体系中部分构件失效,剩余梁则会发生荷载重分布,而荷载重分布对公路钢筋混凝土梁的可靠性分析有较大影响。
There are different between the reliability of bridge-beams system and based components.They are both changing by the bridge-span,main beam distribution and main beam members.As a whole system,there are many lost efficacy.If some of them lost efficacy,the others would be play-load in he other way.That would be effective the analysis on reliability of simple-beam in bridge system of reinforced concrete.
