The High-Speed Railway Bridges Under Vehicle Moving Load And Near Fault Seismic Ground Motions – Review.

Abstract

All-time needs of maintenance of high-speed train system and its infrastructure safety are must all over the world. Nowadays, for the smooth running of HSR trains, most of the country depends on the HSR bridge structures, but there is still a lack of understanding of the behavior of structures under various factors like seismic and high speed moving load effects. To study the dynamic behavior of HSR bridges, it is important to consider the interaction of moving vehicle – Bridge structure – Ground surface showing that the different parameters involved in understanding the response of the structure. The main motivation of this study is to initiate a better understanding of the various parameters effects by those seismic and moving vehicles over the dynamic behavior of the HSR bridges. The effects of forwarding directivity pulses were considered to understand the behavior of HSR bridges against near-fault earthquakes, which can make a substantial impact on the seismic demand capacity of the moving vehicles and structures. The effects of high-speed moving vehicles over the HSR bridges to understanding the parameters involved in the dynamic behavior of the coupled system. This literature review can help the beginners and who initiate the study based on the dynamic behavior of high-speed railway bridges and their components under seismic and moving load effects.

The Analysis of High-Speed Railway Seismic-induced Track Geometric Irregularity

“…In recent years, the development of high-speed railways (HSR) has made significant progress in some regions such as East Asia, Europe, and Africa. More HSRs are being built in hilly areas and coastal seismic fault belts with significant seismic intensity [1], such as in western China and Japan. Due to this situation, the probability of high-speed railways interfering with earthquakes has also grown significantly.…”
