摘要：
This paper presents a method for three-dimensional dynamic analysis of double-deck long-span bridges carrying road vehicles and monorail trains considering the effects of vertical and horizontal surface roughness of the bridge deck and rail tracks respectively. The road vehicle is modelled as a mass-spring-damper system with 7 degrees of freedom (DOFs) while that of the monorail train has 15 DOFs. Then a fully computerized approach is adopted to assemble the governing equation of motion of the coupled system. This coupled system can be reduced to a vehicle-bridge or train-bridge interaction system. Based on this framework, dynamic analysis of a long-span bridge carrying both road vehicles and monorail trains is carried out to investigate the effects of vehicles on the riding comfort of monorail trains and vice versa.
