This model was used to investigate the out-of-phase vibrations and pounding effects of adjacent girders at expansion joints by the nonlinear time-history analysis method.
在此基础上，应用非线性时程方法研究了纵向地震作用下连续梁桥相邻联的非同向振动和伸缩缝处的碰撞效应。
The method can avoid the nonlinear dynamic time-history analysis, and can get more seismic information on structures comparing with the latter.
这种方法可以避免对结构进行复杂的非线性动力时程分析，而且能够得到比动力时程分析更多的结构抗震信息。
