In this paper,rigid-flexible coupling dynamics of a curvic beam attached with a central rigid body undergoing spatial large overall motion,is investigated.
Because the ideal “rigid joint” and “hinged joint” are inexistent, the stiffness of any connection types is between ideal rigid joint and hinged joint.
The prestressed concrete continuous rigid frame bridge is widely used because of its high strength, lightful line type, convenient and fast construction, long-span ability.
