In this study, dynamic behavior of suspension bridge was evaluated under moving truck and lane load specified in the Korean limit state design code. The essential parameters affecting dynamic behaviour of bridges, i.e., road surface roughness and vehicle speed were considered. The road surface roughness was randomly generated based on ISO 8608 and the vehicle speed was considered 60~120 km/h. 3-D finite element model for the selected suspension bridge was constructed and Newmark’s direct integration method was used for bridge-vehicle interaction analysis.
