Abstract A novel numerical methodology is presented to solve the dynamic response of railway bridges under passage running trains, considering soil–structure interaction. It advantageous compared alternative approaches because it permits, (i) consideration complex geometries for bridge and foundations, (ii) simulation stratified soils, and, (iii) solving train-bridge problem at minimal computat...

Infrastructure systems, such as bridges, are perpetually vulnerable to natural hazards seismic events, flooding, and landslides. This study aims determine the relevant parameters required increase resilience of bridge infrastructure based on decisions experts prior research. To this end, crisp DEMATEL (decision-making trial evaluation laboratory) rough methods employed. Rough is a supplement th...

An improved spatial vehicle–track–bridge interaction system considering the unsupported track is proposed using virtual work principle. When fails to be supported due defects under track, corresponding bridge–rail connection coupled matrix should removed. Using dynamic model, a novel numerical analysis of unilateral and bilateral sleepers in bridge subgrade carried out. The results indicate tha...
