Dynamic Analysis of a Vehicle Bridge Interaction System Under Simultaneous Vertical Excitation from Train Induced Ground Vibration and Moving Vehicle
This work presents an advanced 3D-direct time-integration dynamic analysis approach to estimate vertical response for both the vehicle and the bridge of an interacting vehicle–bridge system under simultaneous vertical excitation from train induced ground vibration (TIGV) and vehicle induced bridge vibration (VIBV). The vertical response of an I-shaped girder bridge under the combined effect of TIGV and VIBV on the vertical bridge response has been studied. The FEM software MIDAS GTS NX has been used to simulate the TIGV for a moving train, and the results are verified with the past available literature. The HS20-44 AASTHO truck has been considered for the simulation of VIBV. The 3D vehicle-bridge-train coupled system has been solved using a generated MATLAB code. It has been observed that the vertical vibration generated due to moving train or TIGV affects the bridge response significantly in the presence of VIBV, causing a maximum vertical deflection of 4.28E−3 m.
