Evaluation of 3D Dynamic Effects Induced by High-speed Trains on Double-track Slab Bridges

In this project, 3D models of bridges for double track HSR with slab-track are developed with ABAQUS. The purpose is mainly to verify that 2D models are applicable and conservative for this bridge type. Python and Matlab scripts are written to compute FRF¿s and perform HSLM-analyses for various para...

Sumario:In this project, 3D models of bridges for double track HSR with slab-track are developed with ABAQUS. The purpose is mainly to verify that 2D models are applicable and conservative for this bridge type. Python and Matlab scripts are written to compute FRF¿s and perform HSLM-analyses for various parameter configurations. Finally, post-processing the result of individual parameter sets and over all the parameters sets is done. Moreover, the study of the influence of different load distributions is carried out, depending on the choice of slab-track system.
