摘要：
Beam bridge is forced to vibrate when moving loads pass, which will bring up potential damage to the safety of people and bridge. Tuned Mass damper(TMD) is introduced to study the vibration of beam bridge. A mid-span deflection model of beam bridge is established when moving loads pass with a constant velocity successively. The numerical results shows that TMD can reduce the amplitude of midspan efficiently when long-time moving loads pass through beam bridge.
