曲线模型桥梁结构，这是建造一个典型的全尺寸高弯公路桥梁结构具有相同的功能，分析和实验地震响应之间的相关性。试验桥梁模型的动力性能和地震响应进行了研究，特别强调伸缩缝的不连续行为。描述了伸缩缝处滑动和冲击的库仑型摩擦模型。给出了桥梁模型在三种地震激励下位移响应的相关性。参数进行研究，以协助相关结果的解释和桥梁模型的动态行为的特点进行了讨论。
Correlations between analytical and experimental seismic responses of a curved model bridge structure, which was constructed to have the same features as a typical full-scale high curved highway bridge structure, are presented. Dynamic behaviour and seismic response of the experimental bridge model are examined with particular emphasis on the discontinuous behaviour of expansion joints. Modelling of Coulomb type friction with slippages and impacting at the expansion joints is described. Correlations of displacement response of the bridge model carried out for three seismic excitations are presented. Parameter studies conducted to assist in the interpretation of correlation results are presented and the characteristics of the dynamic behaviour of the bridge model are discussed.
