- Abstract:
-
With the growth of the main span of the cable-stayed bridges,the spatial effect of earthquake motion for the spatial structures becomes a new research topic.Based on stochastic vibration theory and taking the example of SuTong Yangtze River Highway Bridge,the stochastic seismic response of super-long-span,cable-stayed bridge under local effect is developed.The results indicate that the internal force and displacement are influenced obviously by local site effect than by the uniform excitation.For different responses of internal force and displacement of the girder and tower,the impact and the rules are different for seismic ground motion under local effect.Therefore,in view of different cases,the analyses would have different results.
