As the stress amplitude in anchorage zone of cable-stayed bridges vary considerably, it is essential to study fatigue-load-bearing capacity structures cable-stayed-bridge girders. In this study, mechanical properties and force-transmission mechanism a built-in double-fixed steel anchor box, as well influence geometric design parameters main pressure plates support on its performance, were studi...

During the last years, impressive progress has been achieved in the field of speed-up techniques for DIJKSTRA’s algorithm. Due to the availability of road networks, most speed-up techniques were developed for such networks. The fastest known techniques use contraction, a procedure that reduces the graph size, in order to gain their impressive speed-ups. However, in a recent work it was observed...

Safety assessment must accurately grasp deformation information of a high-speed railway bridge. When the ground-based radar collected high-frequency data, white and colored noises will be present in signal due to influence environment instrument errors. The existence above-mentioned two kinds affect accurate estimation information. Based on above situation, real aperture (GB-RAR) method conside...

In this paper, the Difference of Seismic Response across Different Spans (DSR) in longitudinal distribution High-Speed Railway Multi-spans Simply Supported Bridge (HSRSB) under earthquake excitation is investigated, and an evaluation method which can intuitively reflect difference seismic response proposed. A feasible way to strengthen connection stiffness between adjacent girders proposed cont...
