According to the basic design theory, the bridge design method can be divided into: the elastic design method and the plastic method.
钢桥的设计方法按其设计理论大体可分为弹性设计方法和塑性设计方法。
The design method which allows some sections to be part-plastic can improve load-carrying more greatly than elastic design method does.
采用允许部分截面进入局部塑性状态的设计方法，相比弹性设计结构的承载力大为提高。
