摘要: Abstract Some of the possibilities finite element method in moving load problem are demonstrated. The bridge-vehicle interaction phenomenon is considered by deriving a general which believed to be novel. This may regarded as with time-dependent and unsymmetric matrices. bridge response formulated modal co-ordinates thereby reducing number equations solved within each time step. Illustrative examples shown for special case beam model one-axle vehicle model.
