| Research Abstract |
An analytical approach to evaluate the dynamic effect of traffic loads on seismic responses of roadway, railway and monorail viaducts is established and the running safety of vehicles and trains is investigated. Seismic responses of the bridge-train/vehicle interaction system are firstly simulated within linear structural behaviors, and the non-linear seismic analytical approach is also under development. Dynamic effects of traffic loads on bridge response are analytically examined. Influences of soil and ground motion characteristics on seismic responses of bridges are also investigated. The importance of considering properly the dynamic effect of traffic loads in the seismic design of bridges is indicated.
