Figure 10
Comparison between BP neural network time-history results and finite element time-history results: (a) comparison of time-history results of vertical displacement in the middle of the span for dynamic coupling analysis of vehicle-bridge system; (b) comparison of time-history results of vertical speed in the middle of the span for dynamic coupling analysis of vehicle-bridge system; (c) comparison of time-history results of vertical acceleration in the middle of the span for dynamic coupling analysis of the vehicle-bridge system.
