| Abstract: | The natural frequencies of a skew continuous rigid frame bridge on high-speed railway are calculated by using slab model, four beams, two beams and single beam models. It is proposed using four beams model to analysis coupled vibration of vehicle and bridge. Results show that skew continuous rigid frame bridge is of enough stiffness and good unity, the safety and comfort of moving high-speed train can be guaranteed. |
